Singapore’s Land Transport Authority (LTA) is currently evaluating a 3-door, 2-staircase MAN Lion’s City DD L Concept Bus. Bearing the registration plate SG5999Z, the double-deck bus is underwent a six-month revenue service trial on Bus Service 143, operated by Tower Transit Singapore.

The 12.8-metre long concept bus is built on a MAN A95 chassis and packed with new features such as seats with headrests, USB charging ports, stylish interior lighting and a Passenger Information Display System, that gives real-time information on the next bus-stop along its route, integrated with bus stop announcements.

First exhibited at the Our Bus Journey Carnival at Ngee Ann City in March 2016, the bus made its revenue service debut on Monday, 13 March 2017, and is one of two concept buses commissioned by LTA to provide the public with a glimpse of how buses would look like in the future, the other being an Alexander Dennis Enviro500 (2015 Facelift) which will not be entering revenue service trials. 

The six-month trial of the bus with Tower Transit ended on 30 September 2017.

Launch & Overview – Trial with Tower Transit Singapore

The MAN Lion’s City DD L Concept Bus was launched in the morning of 13 March 2017 at a press event in Bulim Bus Depot, marking the start of a six-month trial by the Land Transport Authority (LTA) to evaluate the suitability of such a bus design for Singapore’s use. Bus Service 143 was chosen as it is a long trunk route with a consistent load of commuters.

The bus was first showcased at LTA’s Our Bus Journey Carnival in March-April 2016, and subsequently underwent for modification works prior to revenue service trials. The main design feature of the bus is its two staircases – one going up and the other coming down – giving commuters a dedicated exit route from the upper deck and out directly through the third door.

At the press event, SG5999Z was concurrently exhibited with a 3-door single-deck bus (later bearing the registration SG4002G), a low-entry MAN Lion’s City with steps leading to a third door at the rear, which began trials with SMRT Buses in the second quarter of 2017. Both concept buses were designed by ST Kinetics and built on MAN bus chassis.

Under a Road Traffic (Authorisation of Use) Notification 2017, SG5999Z is permitted to operate on Bus Services 4178106143 and 189, all of which are operated by Tower Transit. The Authorisation of Use also covers bi-directional Off Service routes between Bulim Bus Depot and Jurong East Temporary Bus InterchangeBukit Batok Bus InterchangeToa Payoh Bus InterchangeShenton Way Bus Terminal and ST Kinetics along Corporation Road. 

In the early morning on Sunday, 26 March 2017, SG5999Z performed a revenue service trip on Bus Service 143M, operating under the duty code 143A06, which interlines to 143M on its first trip of the day. According to the Road Traffic (Authorisation of Use) Notification 2017, SG5999Z is not permitted to operate on 143M.

Trial with SBS Transit

In early November 2017, SG5999Z was transferred to SBS Transit and parked at Bukit Batok Bus Depot. Another Road Traffic (Authorisation of Use) Notification is expected to be published, indicating the various bus routes authorised to be trialed by SG5999Z during its trial period with SBS Transit.



Contract PT236 was awarded to Singapore Technologies Kinetics Ltd for S$610,000.00 on 8 Oct 2015, and also to Alexander Dennis (Asia Pacific) Ltd for S$498,500.00, beating Cycle & Carriage, MCV, Yutong and Volvo. The MAN Lion’s City DD L Mock-up Bus was the final product of this undertaking. As Singapore Technologies Kinetics (ST Kinetics) was the local authorised dealer for MAN Truck and Bus in Singapore, accompanied by the close proximity of the bus assembly plant in Johor Bahru, they built their bus on a MAN bus chassis.

The bus is a 12.8-metre long MAN Lion’s City DD L, built on a MAN A95 chassis. Originally 12 metres long, the chassis was manually extended to 12.8 metres, by cutting the chassis before the second axle and adding a chassis extension by welding.

The construction of this bus was done in Gemilang Coachworks, an authorised MAN bus building workshop based in Johor, and subsequently delivered to Singapore as a complete unit. Construction of other Facelifted MAN A95 buses for the Singapore market is detailed in this article.


As compared to older MAN A95 buses, the exterior styling of the MAN Lion’s City DD L Concept Bus bears new styling elements, most notably the large grey stripe on both sides of the bus. The larger headlamp design was likely inspired from MAN Trucks. The livery curves on the upper deck and angled livery overlaying the rear windows makes for a more sleek design with minimal structural modifications.

As a result of its long length, a steerable tag axle allows the bus to navigate corners with greater ease. In the above photo, the bus makes a tight left turn into Toa Payoh Bus Interchange, and the last axle can be seen at a slight angle. The feature is not new; older 3-axle Volvo Olympian buses had the feature on their middle axles.

The bus also features three small Mobitec MobiLED Colour Electronic Display Signages (EDS) for the front, side and rear, allowing the bus to display the service number and special displays in colour. The larger displays on the front and side are conventional Mobitec MobiLED displays, which are white LED matrix displays.

While the service number is programmed in white, Tower Transit has programmed several other logos in colour, including a red-white L-plate for the Training Bus scroll, a LTA logo in blue, and the Tower Transit logo in green.

The bodywork design would later be used in New MAN Lion’s City Facelift DD Buses, which made their debut in February 2017.

    It might not be a trial though, it could be another bus leased to SBS Transit.

    Please update the article. The bus has been transferred to SBS Transit. It was seen logoless and it was last seen at SBS Transit’s BBDEP (Bukit Batok Depot). Most likely transferred to them. If I am not wrong, it was seen logoless and parking at BBDEP (Bukit Batok Depot) on 6 November 2017. Do correct me if I am wrong. Cheers.
