LTA-SBST Joint News Release

History:

Service 121 provides residents of Telok Blangah, Kim Tian and Havelock with greater connectivity to Tiong Bahru and Outram Park MRT Stations, along with other amenities in the vicinity. It is the twenty-fifth (25th) bus service to be introduced under the Bus Service Enhancement Programme (BSEP), and the second new BSEP service originating from New Bridge Road after Service 120.

The intra-town service improves on existing bus connections between the estates at Telok Blangah Way / Crescent / Rise, Kim Tian and Ganges Avenue, and providing the much-needed bus connection between the estates and Tiong Bahru MRT Station. The service also calls at a new pair of bus stops along Kim Tian Road, which had no bus services plying the stretch in recent times.

For the Telok Blangah Estates, Service 121 closely duplicates the existing Feeder Service 272, which did not connect to any MRT station. Residents will enjoy better connectivity to Tiong Bahru MRT with the new service, which is also expected to relieve demand on Service 195.

SBS Transit’s press release sums up the new service:

“SBS Transit Bus Service 121 is a new trunk service that will operate from Sunday, 16 March 2014. Service 121 will directly connect commuters from Ganges Avenue, Kim Tian Road and Telok Blangah Crescent/Rise to Tiong Bahru and Outram Park MRT stations.

Operating daily from 6.00am to 11.30pm from New Bridge Road Bus Terminal, SBS Transit Bus Service 121 will ply Outram Road, Zion Road, Ganges Avenue, Lower Delta Road, Tiong Bahru Road, Kim Tian Road, Jalan Bukit Merah, Lower Delta Road and Telok Blangah Way, before looping back via Telok Blangah Crescent and Telok Blangah Rise. As Zion Road is one-way, the service will ply Outram Road in the return direction.

Besides enhancing connectivity to key transport nodes such as Tiong Bahru and Outram Park MRT stations, the new bus service will also provide residents with convenient access to amenities like Singapore General Hospital, Outram Polyclinic, SAFRA Mount Faber, Tiong Bahru Plaza, markets and food centres along Jalan Bukit Merah and Telok Blangah Crescent, as well as schools such as Radin Mas Primary School and CHIJ St. Theresa’s Convent.

SBS Transit Bus Service 121 is the 25th new bus service to be rolled out under the Bus Service Enhancement Programme (BSEP).”

Bus Service Reliability Framework

The Bus Service Reliability Framework (formerly known as Quality Incentive Framework) was announced by LTA in January 2014. Described as a carrot-and-stick approach, it aims to improve the en-route reliability of bus services. The trial involves monitoring 22 bus services over a period of 2 years and compliments the existing Quality of Service (QoS) Standards which applies to all bus services.

Overview:

Under the BSRF, bus operators will be are provided with monetary incentives to minimise instances of irregular and prolonged waiting times. To resolve such issues, operators are required to enhance their en-route management of bus operations. This involves greater vigilance on the part of Operations Control Centers (OCCs) to make appropriate interventions.

To maintain headway, OCCs will take on a greater role in guiding buses along various routes, which includes making more frequent contact with bus drivers, regulating bus travelling speed and reducing long gaps between consecutive buses. On some occasions, buses may have to wait at a bus stop for a minute or two in order to avoid bus bunching further down the route.

The trial will involve 22 bus services for a period of 2 years. This applies to seven SMRT bus services — 176, 184, 188, 302, 858, 901 and 911 — from Feb 3. It will then be applied to eight SBST services — 3, 17, 39, 52, 228, 241, 242 and 325 — by March. The remaining seven services will be announced at a later date.

Each 0.1-minute (or six seconds) of deviation in the arrival at each bus stop will be compared to a baseline for the respective route, which categories bus routes on their fleet size. Operators face anywhere between a monthly incentive amount of $6,000 or a penalty of $4,000 per 0.1 minute of outperformance or underperformance respectively.

Monitoring reliability:

EWT Performance in 2013

EWT Performance in 2013

Under BSRF, bus operators will be rewarded or penalised based on how regular the bus arrival intervals are at bus stops measured by an indicator known as Excess Wait Time (EWT). The EWT score is a reflection of the overall performance of a bus service and is measured at a number of selected bus stops en-route.

EWT, which is a measure of commuters’ waiting time, compares how the actual waiting time (AWT) of commuters deviates from the scheduled waiting time (SWT). Essentially, EWT is calculated with using the AWT subtracted from the SWT.

A perfect EWT score of 0 minute means that the bus service arrived on time according to schedule for every bus trip during the entire period the service runs. However, in reality, an EWT score of 0 minute is impossible to attain given the nature of bus operations, which is dependent on traffic conditions on the road. Hence, an EWT score of 1 minute is considered good while an EWT score of 2 minutes is considered satisfactory. The lower the EWT score, the better the bus service’s reliability. Longer bus routes tend to have poorer regularity and reliability (due to the compounding effects of traffic conditions) and hence higher EWT scores.

Each bus service has its own existing “baseline” EWT depending on the current performance and the characteristics of the route. Typically, a long trunk route will have a higher existing “baseline” EWT. The EWT of a particular bus service can be improved if bus arrivals at each bus stop become more regular and more evenly spaced. A lower EWT means fewer instances of bus bunching and as a result, commuters should generally experience more regular waiting times and greater ease in boarding as the passenger load will be spread more evenly across the various bus trips.

EWT will be measured during both peak and off-peak hours from Mondays to Fridays, excluding Public Holidays. This will include satellite-based global positioning system data that track public buses, the ticketing system, as well as on-site audits.

Improving reliability:

EWT Baselines for Mar 2014

EWT Baselines for Mar 2014

Under the BSRF, bus operators are given monetary incentives to reduce their EWTs. Reducing EWTs is operationally challenging and additional resources will be required, such as boosting the number of staff at OCCs to manage bus services and having standby buses to be deployed mid-route if there are delays to buses which are already en-route.

Incentives are calibrated in accordance with the efforts and operational costs involved in improving the reliability of the services. Operators are rewarded only when they achieve improvements in bus service regularity, and are penalized if the service is not so. Similar incentive-penalty schemes have been practised in other cities. The BSRF system, including the relative quanta of incentives and penalties, was modeled after London which has successfully implemented a similar programme for over 12 years.

To allow bus operators to adjust to the new framework, a transition period from 3 February until 31 May 2014 monitors EWTs without offering any incentives or penalties.

OCCs can regulate bus speeds by having the bus slow down or hold at bus stops for short intervals, generally no more than about a minute or so and only if it does not cause any obstruction. All buses are already required to adhere to speed limits on the roads, as well as being installed with speed limiters that prevent them from going beyond 60km/h.

The BSRF trial allows LTA to better understand bus reliability improvements that can be made on different types of routes, as well as the BSRF’s effectiveness to get bus operators to improve service reliability, complemented by other regulatory measures such as more strictly enforcing bus lanes and enhancing bus priority schemes and measures. The 22 bus services selected for the trial provide a balance of high frequency feeder and trunk routes with some reliability issues.

Incentive and Penalties:

Incentive amounts are calibrated in accordance to the effort and therefore operational costs involved in improving the EWT performance of a bus service. For example, as it is operationally more challenging to manage and regulate the bus arrival intervals of a larger bus fleet, higher incentives are allocated to services with larger fleet sizes. This also translates to higher penalties for underperformance of services with larger fleet sizes.

For each 0.1 minute outperformance or underperformance in EWT score when compared to the baseline, the following monthly incentive and penalty quantum will apply:

Fleet Size category < 10 buses 10 to <20 buses ≥ 20 buses
Incentive Amount $2,000 $4,000 $6,000
Penalty Amount $1,300 $2,600 $4,000

As BSRF is a significant change to bus operations, there will be no incentives nor penalties until end of May 2014 to allow PTOs time to adjust. Incentives and penalties will be assessed and paid out to the bus operators on a 6-monthly basis, after the phase-in period.

Concerns:

Safety concerns were raised after the announcement of the BSRF , notably as to whether the penalty framework would lead to unsafe driving since bus drivers may be pressured to keep to their schedule. Transport Minister Lui Tuck Yew assured that the BSRF is unlikely to encourage unsafe driving behaviour from bus drivers as the BSRF works by having buses slow down to even out arrival times, instead of speeding up.

In addition, safety will be ensured with speed limiters on buses restricted to 60kmh, and disciplinary actions will be taken against drivers who are found driving recklessly. As operators continue to comply with QoS Standards on accident rates (<0.75 per 100,000 km per month), LTA will closely monitor the trend on BSRF services.

Rail Bridging Services

Rail Bridging Services (or MRT/LRT shuttle buses) are emergency bus services which  are provided in the event of a rail disruption. When a section of the rail network is suspended, these buses would ferry affected commuters between affected stations, hence minimizing the impact of rail disruptions on commuters.

Route Plies between affected stations along the rail network
Passes Through All train stations along the affected stretch
Fares Free travel

Current Depot No restrictions
Current Fleet Any available buses

History:

SMRT Rail Bridging Shuttle

Rail bridging services are a necessary part of rail operations in the event of a service disruption. Due to the high density of urban rail lines, existing modes of public transport are usually unable to cope with the surge of stranded commuters. As such, rail operators are obliged to arrange for shuttle buses that ferry commuters between affected stations.

Due to the multi-modal nature of local Public Transport Operators (PTOs) SBS Transit and SMRT, either operator is responsible for the organization of bus bridging services when their network is affected.

Deployment:

In the past, LTA required PTOs to activate rail bridging services when rail services are expected to be suspended for over an hour. In recent years, buses have been activated at the onset of a disruption and the first buses arrive at affected stations within half an hour after the start of a disruption.

In response to a disruption, buses plying nearby bus routes can be taken out of revenue service to be quickly deployed on the rail bridging service. Subsequently, more buses can be sent from nearby bus depots (or pulled from other bus services) to supplement the buses already running on the shuttle.

Restrictions on buses deployed to rail bridging shuttles are usually dependent on surrounding roads. SBS Transit has not deployed double-deck buses on shuttle routes yet, possibly due to the risk of low headroom when plying certain roads along the route. SMRT frequently deploys articulated buses on its shuttle routes, but however, certain areas like Changi Airport basement cannot accommodate such long buses and hence relies on regular 12m rigid buses.

Route:

Rail bridging shuttles do not have a fixed route; they simply call at affected stations along the rail network. However, PTOs do train their drivers for emergency shuttle routes and may provide route diagrams for bus drivers to follow. Every station on the rail network has designated bus stops where commuters can board the shuttle buses and continue their journey. Such information can be found pasted around train stations. Certain bus interchanges near MRT/LRT stations have dedicated boarding berths for emergency shuttle services.

Regular Bus Services:

At the onset of a disruption, regular bus services calling at affected stations are the fastest way for affected commuters to continue their journey. Under a new agreement by both PTOs, all bus services calling at an affected station offers free travel for commuters boarding at that stop, regardless of operator.

Fares: Free travel for all commuters.

Notable occurrences (unplanned):

  • 15th & 17th Dec 2011: A five-hour and seven-hour delay along the North-South Line between Marina Bay and Ang Mo Kio on both days were the worst disruptions to hit SMRT in over 20 years. Despite the large number of buses deployed, the large scale disruption was difficult to contain.
  • 15th Mar 2012: The North-East Line between Dhoby Ghaut and HarbourFront was suspended for almost 12 hours after a fault discovered in the early hours was not resolved until 4:35pm in the afternoon. Rail bridging services were running throughout the morning and afternoon to ferry affected commuters.

Notable occurrences (planned):

  • 12th & 19th Sep 2010: Train services were suspended on both Sundays between Jurong East and Clementi (on the East-West Line) and between Jurong East and Bukit Batok (on the North-South Line) respectively due to track modification works for the Jurong East Modification Project (JEMP). SMRT deployed large numbers of shuttle buses on both days.
  • 18th Dec 2011: Following the major disruptions of 15th & 17th Dec, the North-South Line, East-West Line and Changi Airport Extension were suspended on Sunday morning as engineers carried out a detailed inspection of the entire train network in what was likely the largest-scale planned shutdown of the train network. SBS Transit provided bus bridging services along the full stretch of the East-West Line, as well as the Changi Airport branch line. SMRT provided bus briding services along the whole North-South Line.

Occurrences in 2014:

  • 11 Jan 2014: Train service between Yew Tee and Woodlands on the North-South Line were disrupted for about two hours, leading to deployment of shuttle buses between affected stations.
  • 22 Jan 2014: Train service between Tanah Merah and Pasir Ris on the East-West Line were disrupted for about an hour due to a trackside fault. Shuttle bus deployed between affected stations but train service resumed shorter afterwards.
  • 7 Mar 2014: A short disruption on the full stretch of the Downtown Line lead to activation of shuttle buses for around half an hour of downtime.
  • 22 Mar 2014: A short disruption between Dhoby Ghaut and Sengkang on the North-East Line led to activation of shuttle buses, however most buses were withdrawn before starting on shuttle service as the fault was quickly resolved.
  • 6 Apr 2014: 1.5hr Service disruption between Potong Pasir and Dhoby Ghaut along the NEL.

Emission Standard Euro IV (EGR)

The Scania K310UD (K-Series 310-bhp Urban Double-deck) is a low-entry wheelchair-accessible double-decker transit bus built by Scania AB. Commonly referred to as the “KUD”, the chassis is manufactured in Europe, and the bodywork supplied by Gemilang Coachworks of Malaysia.

Currently, Singapore’s major bus operator, SBS Transit, is the only operator of Scania K310UDs in Singapore, with a single demonstrator unit to date.

Technical Information:

The Scania K-series is the successor of the Scania L-series and the Scania 4-series. Variants of this chassis can be used as coaches, intercity buses, or urban buses. These include the KUA (Urban Articulated), KUB (3-axle Urban Single deck), KUD (3-axle Urban Double deck), KIB (Intercity Bus) and the KEB (high-end coach). Engine options cover a range of horsepower ratings, from the lowest of 230hp, to the most powerful of 470hp. The full range of engine options is never offered for a particular chassis; for example, the 230hp engine is only available for the KUB chassis.

Unique features of the Scania K-series is the longitudinally, straight-up mounted, inline-cylinder engine located at the rear. The K-series is available with the 9-litre 5-cylinder engine or the 12-litre 6-cylinder engine. Both use Exhaust Gas Re-circulation (EGR) technology to achieve the Euro IV rating. Euro V-rated engines feature both a larger bore and a longer stroke.

SBS Transit K310UD demonstrator (SBS7888K)

Following the successful large intake of the Scania K230UB, SBS Transit acquired a Scania K310UD for demonstration purposes. It was registered as SBS7888K on 26 Mar 2010, during which the Euro V Batch 2 Scania K230UBs were being registered.

Basic Specifications:

  • Scania DC9 18 310 engine
    Inline 5-cylinder turbocharged, 8.867 litres, 310bhp
  • Euro-V compliant
    Exhaust Gas Re-circulation (EGR) technology, doing away with the need for diesel exhaust fluids.
  • ZF Ecomat 6HP602CN gearbox
    Six-speed automatic.
  • Gemilang Coachworks Bodywork
    Custom bodywork designed, built and assembled by Gemilang Coachworks of Malaysia, who also supplied body kits for the Scania K230UBs.
  • Hanover Electronic Display Signages (EDS)
    Orange LED matrix design
  • Carrier air-conditioning unit

The bodywork installed on SBS7888K was the first double-deck bodywork developed by Gemilang Coachworks. The bus was a ‘free gift’ to SBS Transit, paid for by Scania AB after the large number of orders for the Scania K230UB, unlike other demonstrators who are brought in for a trail period only. Similar to the K230UBs, the K310UD is a low-entry bus equipped with one wheelchair bay and a manual ramp. The bus debuted on Service 133M, later transferred to Service 133 and is now a common sight on Service 25.

Additional Specifications:

SBS7888K has a licensed capacity of 132 passengers, inclusive of 55 upper deck seating, 28 lower deck seating, 49 passengers and one wheelchair.

The Volvo B9TL is a rear-engined low-floor double-decker transit bus built by Volvo Buses since 2002. It is the successor to the older Volvo B10TL “Super Olympian” and the Volvo B7TL. The bus is popular in the United Kingdom, Hong Kong and Singapore.

SBS Transit is the sole operator of the Volvo B9TL in Singapore, with 200 units delivered in 2006 with their own bodywork designed by ComfortDelGro. More deliveries are ongoing since 2010 with over 400 buses delivered, built with the Wright bodywork. As of 2013, a Gemilang-bodied B9TL is being built to supplement the intake of new buses.

Design:

The Volvo B9TL chassis was designed based on the existing Volvo B7TL. A key difference from its B7TL and B10TL predecessors is its new 9.3-liter engine originally designed by Renault Trucks. The larger engine delivers more horsepower, an advantage over the Volvo B10TL which was notorious for its poor performance on steep ascents. Another major design change over the B10TL was the relocation of the water tank from the front of the bus (near the right front wheel) to the rear, next to engine components.

The B9TL was initially offered only in a 12-meter 3-axle format. The 2-axle variant was introduced in 2006 to fully replace the B7TL, with various chassis lengths available (10.3m, 10.4m and 10.6m).

The driveline comprises a Euro III-compliant Volvo D9A engine (rated at 300 or 340 horsepower), which was later replaced by the Euro V-compliant Volvo D9B engine, which relies on Selective Catalytic Reduction (SCR) technology, requiring the need for diesel additive fluids such as AdBlue. Two versions were offered – the D9B260 rated at 260-horsepower for the 2-axle version, and a higher powered D9B310, rated at 310-horsepower, for the 3-axle version. Transmission options include a ZF 5/6-speed gearbox or a  Voith 4-speed gearbox. Wheel rims are typically supplied by Alcoa of USA.

SBS Transit Volvo B9TL – ComfortDelGro bodywork

SBS Transit Prototype WAB B9TL

In late 2004, SBS Transit placed orders for 150 Volvo B9TL chassis at a cost of S$71 million on 28 December 2004, then the largest single order of buses. They were going to be fitted with bodywork from ComfortDelgro Engineering (CDGE), a branch of SBS Transit’s parent company ComfortDelgro. The bodywork had previously been built on a Volvo B10TL (SBS9889U), and was ready to be fitted to the Volvo B9TL.

On 15 February 2006, a prototype bus was unveiled, a Volvo B9TL with a zero-step entrance, a manual wheelchair ramp and other wheelchair-friendly features. As Singapore’s first Wheelchair-Accessible Bus (WAB), they were going to pave the way for more WABs and a more disabled-friendly transport system. The launch date was delayed from April to June to prepare bus stops for wheelchair boarding and alighting activities. Finally, on 27 June 2006, SBS Transit Service 21 became the first wheelchair-accessible bus service with 10 Volvo B9TL CDGEs in its fleet.

Volvo B9TL debuts on Service 21

An additional order for 50 more chassis was placed in 2006 at a cost of S$29 million, soon after putting its first B9TLs into operation, bringing the total fleet size to 200. These B9TLs come with the same Euro III-compliant Volvo D9A300 engine, but a four-speed Voith gearbox instead of the six-speed ZF. All units were registered just days before the government-set deadline for Euro-IV compliant diesel engines. The Volvo B9TL CDGE was registered from SBS7300P to SBS7499A.

Basic Specifications:

  • Volvo D9A300 EM-EC01 engine
    Turbocharged & intercooled, 9364cc, 300hp (220kW)
  • ZF Ecomat 6HP592C gearbox (150 units) - Six-speed automatic

Additional features:

Volvo B9TL CDGE fitted with LECIP EDS

In 2011, SBS Transit replaced the traditional plastic destos with Electronic Display Signages (EDS) by LECIP on their Volvo B9TL CDGEs. SBS7392Z was the first bus to receive it, and all other CDGE B9TLs followed suit. The upgrade consists of three sets of electronic displays, for the front, side and rear of the bus. The new LECIP EDSes had route numbers that were considerably smaller, but eventually accepted by many commuters.

On 7 March 2010, SBS7440T from service 25 was burnt beyond repair in a fire at Ang Mo Kio Bus Depot. It was de-registered several months later, making it the first Volvo B9TL in Singapore to be deregistered.

SBS Transit Volvo B9TL – Wright Eclipse Gemini II bodywork [Overview]

The Volvo B9TL Wright is among the most common bus models in Singapore, and introduced into service in different batches. Here, we lay down the differences between each batch for the subsequent article.

The most common bus reference site for Singapore buses, sgwiki.com buses, uses a different format of classifying buses by batch. However, the authors believe that the following is a superior method for the batch classification of the Volvo B9TL Wright:

Batch Reg. No. Notes
Batch 1 SBS7500D – SBS7686B 150 units ; Sep 2010 – Aug 2011
ZF EcoLife 6AP 1410B gearbox
Low-entry
Batch 2 SBS7700T – SBS7729L 30 units; Sep 2011 – Dec 2011
Voith DIWA 864.5 gearbox
Low-entry
Batch 3 SBS3000G – SBS3299L, SBS3600A onwards Deliveries are ongoing. Registration started in Nov 2011, expected completion in 2015
Voith DIWA 864.5 gearbox
Fully Low-floor
BSEP Batch SBS3300R onwards Deliveries are ongoing. Registration started in Nov 2011, expected completion in 2015
Mix of low-floor and low-entry
Specifications identical to several buses of previous batches

In this format, we put more emphasis on technical specifications rather than separating ‘batches’ by their date of introduction.

SBS7500D, the unofficial Volvo B9TL Wright demonstrator, was assembled by Wrightbus in Northern Ireland (UK) and shipped completely-built-up (CBU) to Singapore, where it was used as a reference unit for the local assembly of other WEG2 kits. Built to Hong Kong specifications, an opaque sticker was placed over the upper deck window, where a Roadshow TV screen would have been installed. Also, a rectangular depression was cut out at the rear, where buses in HK would have fixed their registration plates. Finally, the interior flooring differs from other Wrights. Minor differences aside, technical specifications of SBS7500D are identical to other Batch One B9TL Wrights.

Additional Specifications:

Another Batch 1 Wright

The Volvo B9TL Wright has a licensed capacity for 131 passengers, comprising of 55 upper deck seating, 27 lower deck seating, 49 standing passengers and a single wheelchair. Step free access is available from entry to exit door. Safety features include electronically-controlled air suspension, automatic brakes (when doors are open), anti-lock braking system (ABS) and traction control.

The first batch of Volvo B9TLs are also the last batch ever to use six-speed ZF gearboxes. Subsequent batches would all use four-speed Voiths. Although the ZF offers smoother acceleration and performs better at speeds, the Voith offers better initial pickup and lower service intervals.

Several buses were modified with a rear cooling fan on the engine cover to help dissipate heat from the engine.

SBS Transit Volvo B9TL – Wright Eclipse Gemini II bodyworkBatch 2

In September 2010, SBS Transit placed orders for a further 300 units of Volvo B9TLs with the Wright Eclipse Gemini II bodywork produced by Wrightbus. 30 of them were built to similar interior configurations as the Batch 1 Wrights, and these were registered as SBS7700T – SBS7729L, from 21 Sep 2011 – 30 Dec 2011.

Volvo B9TL Wright – Batch 2

Basic Specifications:

  • Volvo D9B310 EC06B engine
    Turbocharged & intercooled, 9364cc, 310hp (228kW)
  • Euro-V compliant
    Selective Catalytic Reduction (SCR) technology requiring diesel exhaust fluids such as AdBlue.
  • Voith DIWA 864.5 gearbox
    Four-speed automatic
  • Wright Eclipse Gemini II Bodywork
    Body kits supplied by Wrightbus of United Kingdom in CKD (complete knock-down) form, assembled locally by SBS Transit’s technical counterpart, ComfortDelgro Engineering
  • Hanover Electronic Display Signages (EDS)
    Orange LED matrix design.
  • Carrier Sutrak air-conditioning, rear-mounted

The only technical difference between Batch 1 and Batch 2A Wrights is the Voith DIWA 864.5 gearbox in place of the ZF EcoLife 6AP 1410B gearbox. The low-entry chassis meant that there was a step on the lower deck between the exit door and the lower deck seating. From Batch 3 onwards, chassis were of the low-floor version.

Although very similar, the lower deck interior flooring has slight modifications as compared to the Batch 1 to accommodate more equipment.

Additional Specifications:

Batch 2 Wright with full-body advertising

Similar to Batch 1 Wrights, Batch 2 Wrights have a licensed capacity for 131 passengers. Step free access applies from entry to exit door. Safety features include electronically-controlled air suspension, automatic brakes (when doors are open), anti-lock braking system (ABS) and traction control.

Several buses were modified with a rear cooling fan on the engine cover to help dissipate heat from the engine.

SBS Transit Volvo B9TL – Wright Eclipse Gemini II bodywork – Batch 3

In September 2010, SBS Transit placed orders for a further 300 units of Volvo B9TLs with the Wright Eclipse Gemini II bodywork produced by Wrightbus, but changed their specifications to a fully-low-floor design, featuring zero-step access from the entrance to the rear row of seats. This specification remains unchanged ever since 2011.

To differentiate them from the Batch 2 Wrights, these buses were registered as SBS3000G - SBS3299L and SBS3600A onwards in numerical order. Deliveries are expected to be completed in 2015, with at least 750 units delivered of this specification.

Volvo B9TL – Batch 2B

Volvo B9TL – Batch 3

Basic Specifications:

  • Volvo D9B310 EC06B engine
    Turbocharged & intercooled, 9364cc or 9368cc, 310hp (228kW)
  • Euro-V compliant
    Selective Catalytic Reduction (SCR) technology requiring diesel exhaust fluids such as AdBlue.
  • Voith DIWA 864.5 gearbox
    Four-speed automatic
  • Wright Eclipse Gemini II Bodywork
    Body kits supplied by Wrightbus of United Kingdom in CKD (complete knock-down) form, assembled locally by SBS Transit’s technical counterpart, ComfortDelgro Engineering
  • LECIP Electronic Display Signages (EDS)
    Orange LED matrix design.
  • Carrier Sutrak air-conditioning, rear-mounted

The initial plan for SBS Transit was to acquire 270 units of this specification (SBS3000G to SBS3269Z). However midway through delivery, 30 buses of this batch were diverted to the then-newly-launched Bus Services Enhancement Programme (BSEP), for deployment on new BSEP routes, as well as the service enhancement of existing routes. This left 240 buses in the batch.

However, in July 2012, SBS Transit placed orders for a further 550 units of Volvo B9TLs with identical specifications, renewing the deliveries of Batch 3 buses. Deliveries are ongoing and expected to be completed in 2015.

These were the first batch of B9TL Wrights to feature LECIP EDS units. All of these buses have identical technical specifications, but registered in different phases.

Additional Specifications:

Another Batch 3 – SBS3269Z

With the new fully-low-floor chassis, the interior configuration was modified. Four of the original side-facing seats were converted into two sets of forward facing seats located behind the exit door. A larger EDS was installed on the nearside of the bus. Licensed carrying capacity increased from 131 to 133 passengers, comprising of 55 upper deck seating, 27 lower deck seating, 51 standing passengers and a single wheelchair.

Several buses were modified with a rear cooling fan on the engine cover to help dissipate heat from the engine.

SBS3189X is currently the only Batch 2B Wright with a Hanover EDS similar to the Batch 1 and 2A Wrights; all other Batch 2B Wrights have LECIP EDS units.

Engine Specification change:

Although the normal Volvo D9B310 EC06B engine is 9364cc, SBS Transit brought in 30 buses with a modified 9368cc engine instead. 20 units were registered for the Batch 3 (SBS3240E – SBS3259C), and 10 units for the BSEP Batch (SBS3330D – SBS3339E).

For background information on the BSEP, read the Bus Services Enhancement Programme article.

The BSEP Batch comprises of all Volvo B9TL Wrights that are under the Bus Services Enhancement Programmed (BSEP). Purchase of these buses are fully paid for by the Government, inclusive of maintenance costs of the bus for the next ten years from initial registration. They were registered as SBS3300R onwards, and deliveries are expected until 2015.

    Orange LED matrix design.
  • Carrier Sutrak air-conditioning, rear-mounted

Technical specifications of the BSEP Batch Wrights are identical to the Batch 3 Wrights.

The initial 30 buses under the BSEP Batch were diverted orders from the 300 buses SBS Transit has announced in September 2010 (Batch 3) to speed up the registration process and acquire a small pool of buses to kickstart the new BSEP routes. Later orders did not interfere much with SBS Transit’s deliveries. All of these buses have identical specifications to the Batch 3, but registered in different phases.

Additional Specifications:

Similar to Batch 3 Wrights, BSEP Batch 1 Wrights have a licensed capacity for 133 passengers. Step free access applies from entry to exit door. Safety features include electronically-controlled air suspension, automatic brakes (when doors are open), anti-lock braking system (ABS) and traction control.

Under the BSEP, these buses are subject to strict deployment regulations, such as being barred from company advertising, and deployment only on BSEP bus routes or enhanced bus routes under the BSEP scheme. Additional onboard equipment installed by LTA can track bus positioning and passenger loading statistics in real time.

Engine Specification change:

Although the normal Volvo D9B310 EC06B engine is 9364cc, SBS Transit brought in 30 buses with a modified 9368cc engine instead. 20 units were registered for the Batch 3 (SBS3240E – SBS3259C), and 10 units for the BSEP Batch (SBS3330D – SBS3339E).

Several units from SBS3761T onwards were fitted with Hanover EDS units.

SBS Transit Volvo B9TL – Gemilang Coachworks bodywork

In 2013, it emerged that SBS Transit was engaging Malaysian bus builder Gemilang Coachworks to design and assemble a new bodywork for the Volvo B9TL. Gemilang had previously designed and assembled its own bodywork for the Scania K230UB and Scania K310UD.

Intended for launch in December 2013, the first unit failed LTA road tests. These buses are expected to enter service in 2014 onwards, with an initial delivery of 100 units. The first unit, SBS7777Y, was registered on 22 Jan 2014 and debuted on 17 Feb 2014, running on Service 7.

The Volvo B10M-60 Mark IV is a mid-engined single-decker transit bus built by Volvo Buses, as part of the B10M line of bus chassis. Commonly referred to as the “Mark 4″, it is the successor of the Volvo B58. Like other Volvo buses, the chassis was manufactured in Sweeden.

Singapore Bus Services (SBS) acquired 475 of such buses between 1994 and 1997, with four different variants of bodywork, namely the PSV, DM, Strider and DM3500. In addition, SBS trailed two demonstrators of this model with extended lengths, both of which were not successful.

Volvo B10M Mark IV – PSV / Soon Chow

In 1993, Singapore Bus Services (SBS) purchased 20 units of the Volvo B10M Mark IV for use on shuttle bus services in Sentosa. Registered as private buses (SH-plate), they were operated by subsidiary company SBS Leisure within Sentosa Island, bearing yellow and green liveries and a Mobitec Flip-dot Electronic Destination Signage (EDS).

SBS chose the 245-horsepower 9603cc Volvo THD102KF engine for this batch of Mark IVs, a slight downgrade from the 273-horsepower Volvo THD101GD engines in the Mark III. The gearbox used was a three-speed automatic Voith DIWA 381.4. Bodywork was supplied by PSV International and assembled by local bus bodybuilder Soon Chow Workshop Pte Ltd. Air-conditioning units were supplied by Sutrak.

SBS Leisure Services:

SBS Leisure operated the Sentosa shuttles with the PSV Mark IVs until their contract with Sentosa terminated in 2004. Ten of the buses were re-registered as SBS8019X – SBS8028U, continuing in numerical order after the Dennis Darts. Their EDSes were removed, and painted with normal SBS livery and entered revenue service. The remaining ten retained their private registration plates, and seven of them were sold to A&S Transport Pte. Ltd.

While SBS8024E and SBS8025C were converted to training buses for Hougang Depot, the remaining eight PSV Mark IVs spent the remainder of their lifespan on Service 78 under Soon Lee Bus Park. With the entire fleet doing revenue service on Service 78, special deployments of these buses to other bus services were sought after by bus enthusiasts.

Nearing their 15-year lifespan, some PSV MkIVs received a refurbishment to extend their lifespan by two years, including the two training buses in Hougang Depot. The last of them retired in 2011.

—————————————————————————————————————————————

Volvo B10M Mark IV – Duple Metsec

In 1995, Singapore Bus Services (SBS) further purchased another 115 units of the Volvo B10M Mark IV. Registered as SBS882U – SBS996C between Aug 1994 and Apr 1996, they were in direct numerical continuation after the Volvo B10M Mark III. These batch of buses come in two engine and two gearbox variants.

Volvo B10M Mark IV – Duple Metsec

Basic Specifications:

  • Volvo THD101GD engine [8 units]

  • Sutrak air-conditioning, roof mounted

Currently, they typically serve on short and medium-haul routes which have not been declared WAB.

Additional features:

External advertising boards on SBS957R

The Volvo B10M MkIV has a licensed capacity for 82 passengers, comprising of 50 seated and 32 standing passengers

Some MarkIV DMs were fitted with external advertising boards, such as SBS885P, SBS896H, SBS906M, SBS919B, SBS921T and SBS957R. Known as “skyliners”, they pop out of the bus and charge special advertising rates. These mobile billboards are maintained by Moove Media, the advertising arm of ComfortDelGro Corporation, SBS Transit’s parent company.

In addition, SBS910A has a modified seating configuration, with a long side-facing seat for three people at the nearside of the bus, in place of two front-facing seats for four people. An advantage of this design is more legroom for commuters, as the Mark IV DM has notoriously small legroom for some seats. SBS984L has grills on the offside of the bus, unlike other Mark IV DMs.

Volvo B10M Mark IV – Walter Alexander Strider

In 1995, Singapore Bus Services (SBS) further purchased another 150 units of the Volvo B10M Mark IV. Registered as SBS1896B – SBS1999M, they were a direct continuation of the Volvo B10M Mark III. The remaining buses were registered as SBS2593T – SBS2688D, a numerical continuation after the Mercedes-Benz O305s. The difference in registration numbers do not represent a different batch; SBS simply did not want to continue the registration after 1999M in conflict with their retired Albion Vikings and OF1413 using the numbers in the past. Buses were registered from 26 Oct 1995 to 24 Feb 1997.

Volvo B10M MkIV – WA Strider

Additional features:

External advertising boards on SBS1908B

The Volvo B10M MkIV Strider has a licensed capacity for 84 passengers, comprising of 48 seated and 36 standing passengers

Some MkIV Striders were fitted with external advertising boards, such as SBS1908B, SBS1985C, SBS1988U, SBS2608K and SBS2619D. Known as “skyliners”, they pop out of the bus and charge special advertising rates. These mobile billboards are maintained by Moove Media, the advertising arm of ComfortDelGro Corporation, SBS Transit’s parent company.

In addition, SBS1973L had CCTV cameras installed at the rear for safer reversing, and SBS2652G had solar panels installed on the roof. SBS1992G was sold to National Library Board and converted to a mobile library nicknamed “Molly”, now registered as XD5296A.

The last four registered Striders, SBS2685L to SBS2688D, were JB-registered to replace the retiring Volvo B10M MkIIIs on cross-border routes.

—————————————————————————————————————————————

Volvo B10M Mark IV – Duple Metsec DM3500

In 1996, Singapore Bus Services (SBS) purchased 150 more units in its final batch of the Volvo B10M Mark IV orders. Registered as SBS2689B – SBS2838M from Aug 1997 to Dec 2000, they were a direct continuation of the Volvo B10M Mark IV Striders.

Additional features:

The Volvo B10M MkIV has a licensed capacity for 87 passengers, comprising of 46 seated and 41 standing passengers.

External billboard advertising

Some MkIV DM3500s were fitted with external advertising boards, such as SBS2691T, SBS2722M and SBS2826Y Known as “skyliners”, they pop out of the bus and charge special advertising rates. These mobile billboards are maintained by Moove Media, the advertising arm of ComfortDelGro Corporation, SBS Transit’s parent company.

In addition, SBS2754X had out-swinging plug doors for the exit doors, instead of the traditional in-swinging leaf doors. SBS2779A was equipped with an orange Transit Media Electronic Display Signage (EDS), which was removed some time in 2010. 75 buses of this batch were JB-registered in 2011 to replace the retiring Volvo B10M MkIIIs on cross-border routes.

Two DM3500s also had complete interior makeovers. These ‘concept buses’ were fully refurbished with special interior layouts as part of long-term advertising. SBS2696E was converted into Nokia Music Mobile buses, with side facing seats, armchairs and a mock-up bar (SBS2779A and SBS2812L only bore the advert). SBS2837R was converted into a HP concept bus featuring seats with headrests, and various HP products displayed in the interior. For pictures, check out the sgbuses.com gallery here and here.

Gearbox ZF 4HP 590
Emission Standard Euro 2

The Scania L94UB is a low-entry single-deck transit bus built by Scania AB as part of the Scania 4-series. Commonly referred to as the “L94″, the chassis is manufactured in Europe, and the bodywork supplied by Australian bus bodybuilder Volgren. Originally available with a Euro 2 engine, options for a Euro 3 and CNG engines were avaliable later. The chassis was built as a direct replacement for the Scania L113 (which were already on the roads of Singapore back then) but later succeeded by the Scania K-series.

Currently, SBS Transit is the sole operator of the L94UB citybus in Singapore, with a single demonstrator unit (SBS2888T).

Technical Data:

Similar to the Volvo B10BLE, the Scania L94UB incorporates a low-entry design featuring zero-step access at the entry and exit doors, allowing for safer and easier boarding and alighting activity. Three-branch stanchion poles opposite the exit door allow more passengers to hold on to them.

The powerplant of this bus is a rear-mounted, turbocharged Scania DC902 inline six-cylinder delivering 260 horsepower, and a four-speed ZF gearbox (ZF 4HP 590). The Euro 2 rated engine made it one of the most environmentally-friendly buses when it was introduced. In contrast to drum brakes of older buses, the Scania L94UB uses disc brakes for its front wheels, allowing for more uniform and stable deceleration of the bus.

—————————————————————————————————————————————

Demonstrator Unit (SBS2888T):

SBS2888T was one of two two low-floor single deck demonstrators brought in by Singapore Bus Services in 1999 (alongside SBS1688K). Bodied by Volgren, it featured a Scania DC902 Euro II engine (8,974cc) with a ZF4HP590 gearbox and a Mobitec flip-dot Electronic Destination Signage (EDS). Air-conditioning was supplied by Sutrak. Many of its innovative features, such as Anti-lock Braking Systems (ABS), rear exit plug-doors, and electronically controlled suspension, were to eventually become standard with the much later K230UB fleet. Similar to the B10BLE demonstrator (SBS1688K), this bus also received the CR221L bodywork from Australian bus bodybuilder Volgren.

Having been deployed to Express 518 for a long period of time, it was converted to a training bus, and will likely remain so for the rest of its lifespan. It is commonly sighted doing rounds at Hougang Bus Depot, training new batches of bus drivers. Its lifespan expiry date is 08 Apr 2016.
