The MAN NL323F (A22) is a fully-low-floor, rear-engined single-decker transit bus built by MAN Truck & Bus since 2007. It was sold to various operators around the world, particularly in Germany, Spain, Israel, Singapore and the UK.

Currently, SMRT Buses is the sole public transport operator with the MAN NL323F, with 402 units acquired in its first two batches. Deliveries are ongoing, with a third batch of additional buses.

With the gradual implementation of the Government Contracting Model (GCM), MAN A22 buses owned by the Government will also be operated by Tower Transit, who was awarded the Bulim Bus Package.

Technical Information:

The MAN NL323F A22 is a chassis designed off MAN’s popular urban bus line, the Lion’s City, which was only available with integral bodywork by MAN. The NL323F is available with various bodywork designs from different manufacturers.

MAN NL323Fs come with the standard MAN D2066 LUH inline 6-cylinder, horizontally-mounted, turbocharged & inter-cooled engine, with a rage of available power outputs of between 270 and 400 horsepower over Euro III to Euro V emission standards. For the Euro V rating, 320hp, 360hp and 400hp versions are available, along with a 2-stage turbocharger for high torque rating. The engine uses Exhaust Gas Re-circulation (EGR) technology and MAN’s own PM-Kat® exhaust treatment system to achieve its Euro V rating.

For transmission, the MAN NL323F offers a Voith 4-speed automatic transmission as standard, with an optional offering of a ZF EcoLife 6-speed automatic transmission. The integrated hydraulic retarder features boosted operating economy, longer service life, and higher temperature resistance for operation with Euro V compatible engines. A portal axle is used for the rear wheels, and all wheels come with disc brakes. Similar to other MAN urban buses, the NL323F chassis in manufactured and assembled in Salzgitter, Germany.

Hybrid-electric, compressed natural gas (CNG) and regular diesel powered variants of the MAN A22 are available, all capable of meeting Euro-VI emission standards.

SMRT Buses: A Brief History

As SMRT’s fleet of Mercedes-Benz O405s fast approached retirement age, there was a need for a large replacement of 12-metre buses that was wheelchair accessible and environmentally friendly. The MAN NL323F was largely successful in these aspects, with over 402 units acquired between 2010 and 2014.

SMRT’s first MAN NL323F was a demonstrator unit bodied by MCV (Manufacturing Commercial Vehicles) of Egypt, of the MCV Evolution bodywork. Registered as SMB138Y, it entered service in December 2010 and delivered satisfactory performance during its one year trail period. It was also favored over SMB136C (SMRT’s Citaro demonstrator) as a suitable bus for large-scale fleet renewal and expansion. SMB138Y was taken out of revenue service in 2012.

The following year, SMRT announced purchases of 200 additional MAN NL323Fs, this time with a MAN Lion’s City Hybrid bodywork manufactured and assembled by Gemilang Coachworks. In 2013, another 202 units were announced and brought in. Deliveries concluded by early 2014, with 402 units acquired. Part of these deliveries were diverted to the Bus Services Enhancement Program.

SMRT announced a third batch of MAN NL323Fs in April 2014, with an additional bulk order of 332 units. Deliveries started in mid-2014 and are expected to continue over the next few years.

SMRT MAN NL323F Demonstrator (MCV Evolution) – SMB138Y

In 2010, SMRT Buses received a MAN NL323F demonstrator unit for road testing and evaluation by MAN’s local dealer, ST Kinetics. The bus was registered on 17 Dec 2010 as SMB138Y, the fifth demonstrator unit received by SMRT Buses.

SMB138Y Interior

Basic Specifications:

  • MAN D2066 LUH-32 engine
    – Twin-turbocharged, 10.518 litres
    – 320 hp (235 kW) @ 1900 rpm
    – Torque rating of 1600 Nm @ 1000 – 1400 rpm
  • Euro-V compliant
    Exhaust Gas Re-circulation (EGR) technology and MAN’s own PM-Kat® exhaust treatment system, hence doing away with the need for diesel exhaust fluids.
  • ZF EcoLife 6 AP 1700 B gearbox
    Six-speed automatic for high torque output.
  • MCV Evolution Bodywork
    Chassis built in Germany, bodywork supplied by Manufacturing Commercial Vehicles (MCV) of Egypt, of the MCV Evolution build. Final assembly performed by local bus builder Soon Chow Workshop.
  • Hanover Electronic Display Signages (EDS)
    Orange LED matrix design
  • Denso LD8i air-conditioning unit
    Similar to the ones fitted to Scania K230UBs.

Inside, SMB138Y was fitted with the standard blue, purple and red Volgelsitze seats, the interior color scheme of choice for SMRT. Like the previously-introduced Citaro demonstrator (SMB136C), it has a single wheelchair lot equipped with a foldable seat for two people. The rear row of seats has just four seats, with extra space taken up by engine components. It the first SMRT bus to be equipped with a TV screen (from LG), which plays SMRT commercials. Free Wi-Fi access is also available.

The rear exit doors of SMB138Y were sliding plug doors supplied by Ventura Systems (based in the Netherlands), a first for public buses in Singapore. The door is pushed out of the door frame before sliding open, unlike the existing swinging plug doors which can only swing outwards. The reduced outward swinging distance of the sliding plug design brings along additional safety, of not hitting people or objects at bus stops. The sliding plug design would be later incorporated in production batch MAN NL323Fs (from a different manufacturer), and future Alexander Dennis Enviro500s would continue to use Ventura sliding plug doors.

SMB138Y made its debut on 29 December 2010, appearing on SMRT Service 961 between Woodlands and Lorong 1 Geylang. The powerful engine had no problems coping with a long trunk route, and was under the control of Woodland Depot (WLDEP). It was also the only SMRT bus to provide free onboard Wi-Fi.

On 18th January 2011, SMRT released information about SMB138Y in a press release:

“Encouraged by the positive experience of our passengers on the low-floor Citaro trial bus, SMRT introduced on trial another full low-floor bus on 29 December 2010 – the MAN A22 by German manufacturer MAN AG – for the convenience of passenger movement within the bus. On top of its state-ofthe-art low floor configuration, the MAN A22 bus is Euro 5 compliant without additives. This is made possible because of an additional maintenance-free PM-Kat© filter in the engine. This patented technology does not increase fuel consumption, making it a cost efficient yet environmentally-friendly bus. The MAN A22 also has a first of its kind Sliding Plug Exit Door. This unique door swings out from the bus body then slides open, enhancing passenger safety as it prevents passengers from accidentally being hit by the door as it closes.

The MAN A22 will be on trial for one year, and has started serving commuters on Service 961 from Woodlands Regional Interchange, plying through Upper Bukit Timah, Queensway, Eu Tong Seng Street and Raffles Boulevard. It will move on to serve Service 902 from middle of the year.”

SMB138Y was later redeployed to Service 963, making occasional appearances on 169A, 962 and 963E, before being transferred to Ang Mo Kio Depot (AMDEP) and redeployed to Service 985. It had made special appearances on 61, 106, 167, 851, 857, 858, 858A, 960, 963R, 966 and 971E.

The trial of SMB138Y was ultimately successful, with SMRT initiating further purchases of the MAN NL323F chassis of a different bodywork. Following water damage to its electronics in 2012, the bus was laid up for maintenance, and never saw revenue service again. In early 2013, the bus was returned ST Kinetics after two years on the road, concluding its trial period, and eventually deregistered in November 2014.

In March 2015, the bus was spotted undergoing refitting works at Gemilang Coachworks, where SMRT’s MAN A22, A24 and A95s are assembled. The eventual fate of the bus was traced only in November 2015, when it was spotted in Sydney, Australia for Carbridge, an Australian bus company supporting airport operations. The bodywork was extensively modified to resemble the MAN Lion’s City Hybrid bodywork, with a single leaf exit door.

SMRT MAN NL323F Production Batch 1 (Lion’s City Hybrid / Gemilang): SMB189A – SMB354P

Following the successful trial of SMB138Y, SMRT Buses placed orders for 200 more MAN NL323Fs as part of a fleet renewal programme, bodied by Gemilang of the Lion’s City Hybrid design. 166 units fall under the Production Batch 1, registered between 15 Sep 2011 and 30 Nov 2012 as SMB189A – SMB354P. The remaining 34 buses were registered under the BSEP Batch 1.

    – 320 hp (235 kW) @ 1900 rpm
    – Torque rating of 1600 Nm @ 1000 – 1400 rpm
  • Euro-V compliant

  • Gemilang / Lion City Hybrid Bodywork
    Chassis were built in Germany, MAN’s Lion City Hybrid bodywork supplied and assembled by Gemilang Coachworks licensed by MAN.
  • Mobitec MobiLED Electronic Display Signages (EDS)
    Orange LED matrix design
  • Denso LD8u air-conditioning unit

The bodywork used on these buses were similar to MAN’s Lion City Hybrid buses, but manufactured by Gemilang Coachworks of Malaysia, under license from MAN. Like other MAN buses, the chassis was built in Germany. They were then assembled by Gemilang in Malaysia before final delivery to Singapore. One of the most distinguishing feature of the production batch is the enlarged roof design, which in the original Lion’s City Hybrid, helps divert air to cool electrical components located on the roof. For the production batch of MAN NL323Fs, the roof is less useful and simply conceals the air-conditioning pod.

Inside, Production Batch 1 NL323Fs were fitted with the standard blue, purple and red Volgelsitze seats, the interior color scheme of choice for SMRT. Similar to SMB138Y, it has a single wheelchair lot equipped with a foldable seat for two people. The rear row of seats has just four seats, with extra space taken up by engine components. The unique sliding plug door design was retained from the demonstrator unit, but with new doors supplied by Masats of Spain, featuring much faster opening and closing operation.

On 1st October 2011, SMRT released information about the Production Batch MAN NL323Fs in a press release:

“The 12-metre wheelchair accessible MAN A22 bus has a state-of-the-art low floor configuration designed for the convenience and safety of all passengers, allowing ease of  boarding and alighting especially for the elderly and less mobile. Working with MAN’s sole distributor ST Kinetics, SMRT has also configured the bus to have one space for  passenger-in-wheelchair (PIW), which is built with a flip-down seat for other passengers when there is no PIW aboard.

Designed with a unique Sliding Plug Exit Door which swings out from the bus body then slides open, it prevents passengers from accidentally being hit by the door as it closes, thus enhancing passenger safety. The bus is also equipped with the Electronic Braking System, a safety mechanism that offers better braking efficiency than most buses. Its improved braking response time enhances passenger safety as it allows drivers to handle tricky road situations more easily.

The bus features a more spacious interior with higher headroom for better comfort and a specially designed bus body for SMRT Buses and the Singapore market. Its futuristic design incorporates a sleek bus front forehead that is one-of-a-kind in Singapore.

On top of delivering safety and comfort to passengers, the MAN buses are also environmentally-friendly as they are Euro 5 compliant without the need of chemical additives. This is made possible with the addition of a maintenance-free PM-KAT© filter in the engine. We welcome passengers to give us feedback on the new MAN A22 buses at www.smrt.com.sg from Monday, 3 October 2011.”

On the same day, SMRT organised a handover ceremony at Hort Park, featuring SMB189A and SMB191S. SMB191S was registered just a day before the ceremony, and SMB190U was not present due to a suspected mechanical fault.

On 3rd October 2011, SMB189A made its debut on Service 963 and 963E, as reflected in the press release. Originally equipped with an additional step before the rear row of seats, the step was subsequently removed.

Additional Specifications:

The MAN A22 has a licensed carrying capacity of 90 passengers, consisting of 38 seated, 52 standing and one wheelchair.

In 2013, 20 units of the MAN NL323F were SPAD-registered for deployment on cross-border Service 950, replacing the previous fleet of Mercedes-Benz O405s and OC500LEs.

Some units have been repainted with SMRT Buses’ new livery.

In 2012, SMRT Buses placed orders for an additional 202 more MAN NL323Fs as part of a fleet renewal programme, bodied by Gemilang of the Lion’s City Hybrid design. These 200 units would be distributed between the Production Batch and the BSEP Batch.

In 2014, additional buses were registered under the BSEP Batch 2, exceeding the original total of 200 buses. More buses were ordered as part of SMRT’s original delivery of buses were diverted to the BSEP scheme.

Buses of this batch are identical in all specifications to their Batch 1 counterparts. Compared to the first production batch, two extra grab poles were installed at the front of the bus, and door movement markings pasted on the floor underneath the front door.

Delivery:

SMRT took delivery of these buses between 2012 and 2014. Batch 2 MAN NL323Fs (120 units) were registered between 24 Jan 2013 and 6 Jan 2014, while BSEP Batch 2 MAN NL323Fs (82 units) were registered from 1 Mar 2013 onwards. The later units of both batches were delivered with the SMRT Buses’ New Livery.

Additional Specifications:

Buses under the BSEP scheme are subject to strict deployment regulations, such as no 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.

The MAN A22 has a licensed carrying capacity of 90 passengers, consisting of 38 seated, 52 standing and one wheelchair.

Some units have been repainted with SMRT Buses’ new livery.

Modified Seating Configuration:

Some Batch 2 NL323Fs are fitted with a modified seating configuration. Two seats at the front of the bus were removed to make way for a larger standing area, similar to the Mercedes-Benz O405G Mark Is. At the rear, another seat was removed to make the aisle more spacious for standing passengers.

Buses with the modified seating configuration are:

  • Production Batch 2: SMB1341U, SMB1363G onwards
  • BSEP Batch 2: Most units

These buses have a licensed carrying capacity of 91 passengers, consisting of 35 seated, 56 standing and one wheelchair.

SMRT MAN NL323F Production + BSEP Batch 3 (SMB1421Y – SMB1650C)

In April 2014, SMRT announced the further purchase of 332 more MAN 12-metre buses. A large proportion of this new delivery will be additional MAN NL323Fs for the mass replacement of retiring Mercedes-Benz O405s.

Technical specifications of the new Production Batch are similar to the demonstrator unit, with slight modification to the exterior (noticeably the rear registration plate holder). These buses have been in the process of registration from 8 July 2014 onwards, starting with SMB1421Y and continuing in numerical order.

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

Buses of this batch are identical in all specifications as their Production Batch counterparts. The cost of acquiring these buses and maintenance costs for the next 10 years after their introduction are borne by the Government under the BSEP scheme.

Under the BSEP, these buses are subject to strict deployment regulations, such as the lack of commercial advertising, and deployment only on BSEP bus routes or enhanced bus routes under the BSEP scheme. Additionally, LTA can track bus positioning and passenger loading statistics in real time. Because these BSEP buses are drawn from SMRT’s existing orders, minor interior specifications will be similar to the Production Batch which they were acquired from.

BSEP Batch Corresponding to Registration
BSEP “Batch 1” Production Batch 1 SMB3001M – SMB3034T
BSEP “Batch 2” Production Batch 2 SMB3035R – SMB3116R

11 thoughts on “MAN NL323F A22

  1. For BSEP Batch 2 Modified seating configuration is
    (SMB3052R – SMB3116R), for normal Batch is until SMB 1420A and SMB3117M is Batch 3 not 1.

  2. Inside Batch 3 interior, there is also 1 extra grabpole at the wheelchair bay. From SMB15×× series (if I am not wrong), all bus will bear with a full red SMRT logo instead of half red and half black. From SMB3117M, it should be BSEP Batch 3, not BSEP Batch 1(taken from what Johnny had said).

  3. The Design is Based on the MAN Lion’s City Hybird, that’s Why it is Use for Power Capacitors to power the Traction Motors but in Singapore, This was use for the MAN A22 Chassis as MAN NL323F, the Height is a Litter Higher than the SBST K230UBs.

  4. The registration for MAN NL323F Batch 3 did not stopped at SMB1620P. SMB1621L to SMB1650C was registered as Batch 3, and deliveries may also be ongoing.

  5. The newest SMRT MAN A22 NL323F started registrations from SG1700U from today onwards (Monday, 01st February 2016) under the Government Contraction Model (GCM) for the Bus Service Enhancement Programme (BSEP) registrations for SG registrations of.
