A Bulim Carnival Day


“A Bulim Carnival Day” was an opening ceremony cum depot open house held on 6 December 2015 at the Bulim Bus Depot. It was organized by Tower Transit, the successful tenderer of the Bulim Bus Package, which will operate 26 bus routes out of the depot starting from May 2016.

The event provided a platform for Tower Transit Singapore to showcase its new depot, while educating the public on what to expect when the GCM kicks in from next year. In addition, static display buses were open to public viewing, and job-seekers could sign up for job opportunities with Tower Transit.

Tower Transit was first established in London and Cambridge where it operates 650 buses, employs 2,000 people and carries over 115 million passengers a year. It was shortlisted for the title of Bus Operator of the Year in the 2015 London Transport Awards. It is a sister company of Australia’s leading Transit Systems Group which has over 19 years of operating experience with tendered government contracts in Australia. It now operates over 1,000 buses, employs more than 2,000 people and carries over 55 million passengers per year.

The company entered the Singapore bus scene when it bidded for, and was subsequently awarded the Bulim Bus Package, a route package comprising 26 bus routes based out of the new Bulim Depot. This was the first contract awarded by LTA as part of the Government Contracting Model (GCM), which will introduce a competitive scene of bus operators bidding for various route packages and a share of the market.

Coming May 2016, Tower Transit will take over the 26 bus routes in 3 tranches, as well as the managing of Jurong East and Bukit Batok Bus Interchanges. It will then operate these routes for five years, with a two-year extension granted based on good performance.

Getting to the Carnival

A shuttle bus service was arranged to loop between Bulim Bus Depot and Boon Lay MRT, picking up and dropping off participants on a rolling basis. The pick-up point at Boon Lay was the bus stop along Boon Lay Way, where CW6 also calls at.

Volvo B9TL buses registered with the SG-prefix were used on the shuttle, featuring green and white recruitment advertisements by Tower Transit. SG5006PSG5007LSG5008J and SG5009G were deployed, all featuring similar recruitment adverts in different languages on the nearside.

The Carnival

Arriving from the main entrance, guests would be provided an activity card containing a event layout map, lucky draw ticket, and coupons for food, snacks and drinks. The administration building of the depot was used to host the event, with the large sheltered area on the ground floor intended for parking of buses in the future.

At the carnival, there were mini-exhibitions by Tower Transit Singapore, Volvo, Alexander Dennis Limited (ADL) and MAN, a display of bus liveries, and food and drinks. A bus design competition was also held, where the winner will have their design featured on an actual bus. A bouncy castle, airbrush tattoos, a photobooth and balloon-sculpting were activities arranged for children. Participants who were present at the event at 2:00PM would have been able to watch the official opening ceremony of the Bulim Bus Depot by Senior Minister of State Dr. Amy Khor and Tower Transit Group CEO Adam Leishman.

Other than the main event area, participants could sign up for a walking tour of the depot administration areas and taking a bus ride through the bus refueling area and bus wash.

Static Bus & Bus chassis displays:

Volvo, Alexander Dennis Limited (ADL) and MAN, manufacturers of various bus models operated by Tower Transit, set up booths at the event. Under the Government Contracting Model (GCM), Tower Transit would operate Volvo B9TL and Alexander Dennis Enviro500 double-decker buses alongside MAN NL323F and Mercedes-Benz Citaro single-deck buses, all of which would be government assets loaned to Tower Transit for the duration of the contract period. While Mercedes-Benz did not set up a booth at the event, one Mercedes-Benz Citaro was showcased on static display.

The static displays showcased both Volvo B9TL and MAN NL323F chassis, along with completed Volvo B9TL, Mercedes-Benz Citaro and MAN NL323F buses. SG1002B, SG5002A and an unregistered MAN NL323F was featured.

The Volvo B9TL (Wright Eclipse Gemini II bodywork) on display was registered SG5002A, built to SBS Transit’s latest “Batch 4” configuration which are also running on revenue service.  This configuration featured a straight staircase (with two staircase landings) and increased legroom for the front seats of the upper deck.

Under the GCM, Volvo B9TL buses were procured by tapping into SBS Transit’s existing orders, hence retaining identical technical specifications and interior design. Just like its SBS Transit cousins, these buses were assembled using complete knock-down (CKD) kits produced by Wrightbus. They are assembled locally by ComfortDelGro Engineering, the engineering branch of SBS Transit’s parent company ComfortDelGro, at the bus assembly plant at Hougang Bus Depot.

The Mercedes-Benz O530 Citaro on display was registered SG1002B and built to SBS Transit specifications. Under the GCM, Mercedes-Benz Citaros were procured by tapping into SBS Transit’s existing orders, hence retaining identical technical specifications and interior design. These buses were built in Germany and shipped completely-built-up to Singapore.

The MAN NL323F on display was unique in not featuring any special Tower Transit livery, but rather SMRT’s silver-grey base coat (prior to application of its pixel-design livery) with additional decals on its glass panels promoting the MAN bus. The unregistered bus is likely to be fresh from the Gemilang Coachworks assembly line and borrowed from local dealer ST Kinetics for the event.

Under the GCM, MAN NL323F buses (also known as the MAN A22) were procured by tapping into SMRT’s existing orders, hence retaining identical technical specifications and interior design. Just like its SMRT cousins, these buses were assembled by Gemilang Coachworks Sdn Bhd in Senai, Johor, with bodywork similar to MAN’s Lion City Hybrid buses under license from MAN.

However, on-board equipment such as the Integrated Driver’s Fare Console (IDFC) system, card readers and the coinbox were yet to be installed.

While Alexander Dennis Limited (ADL) did not have a static bus on display, a booth was set up. At that point of time, BSEP-registered Alexander Dennis Enviro500 units in Singapore werestill  in service with SMRT and yet to be handed over to new GCM operators.


Walking Depot Tour

Guided tours of the administration building were organised for participants to get a glimpse of the inner workings of the depot. The depot offices, operations control centre, drivers’ rest area and canteen were among the areas featured along the tour, which occupy the second floor of the administration building.

The first stop is the Tower Transit depot office, which was designed around the open office concept. Without cubicles, staff are more free to interact and move around, and the whole office has a more spacious feel without barriers in the way.

The operations control centre (OCC) is the heart of all Tower Transit bus operations, or at least it would be, once all the computers are installed in the near future. Apart from the regular team of staff who take care of bus operational matters, a separate team of staff would be dedicated to spacing buses apart and maintaining headway, crucial in keeping the Excess Wait Time (EWT) to a minimum. The EWT of a bus service is the main quality indicator of on-time adherence, and a low EWT score indicates that buses are operating with minimal deviation from schedule.

A dispatch office is also present, where bus drivers report to at the start and end of the work day. A counter next to the canteen and recreation area would be where drivers collect and return the bus logbooks, time sheets and other relevant documents for their shift.

The canteen and recreation area is the showcase of Tower Transit’s commitment to driver welfare, which they have termed “the best in the world”. Air-conditioned and bathed in natural lighting, the recreation area guarantees comfort for employees, especially bus drivers who are not on the roads. This mainly caters to drivers on the split shift, who only drive during the morning and evening peak hours with a long break in between.

Apart from tables, chairs and sofas, table soccer and table tennis are provided for recreational use. Interior furniture and table games were provided by Tower Transit themselves.

Bus Refueling and Bus Wash Tour

A tour of the bus refueling and bus washing areas was organised with two Volvo B9TL buses, SG5003Y and SG5004U, making their rounds around these two areas. Both buses featured SBS Transit livery (without the company logo) on the sides, and a full white front and rear.

Upon the end of their shift, bus captains returning to the depot would hand over their buses a specialised team of staff called shunters, which would perform the refueling, washing and parking duties of incoming buses. This is in contrast to SBS Transit and SMRT, where these duties would have normally been carried out by bus captains.

Designed for ten buses at a time, the refueling area has ten lanes to top up buses with diesel after a long day on the road. Currently, only one lane is equipped with an AdBlue pump. Used as a diesel exhaust fluid, AdBlue is a diesel exhaust fluid (DEF) used on buses employing Selective Catalytic Reduction (SCR) technology, which are the Volvo B9TL, Mercedes-Benz O530 Citaro and Alexander Dennis Enviro500 buses.

After refueling, buses head straight for the bus wash. Five automatic bus washing machines rinse off dust and dirt accumulated after a day of operation on the roads. Finally, buses would be parked throughout the depot.

  1. Spotted one of the buses (SBS Volvo B9TL) with Tower Transit livery on the day of the carnival at Pioneer Rd North towards Nanyang Cres after JW St 63. Didn’t know about the carnival until the evening news.
