In April 2019, the Land Transport Authority (LTA) procured 50 units of the MAN A95 (Euro 6) double-deck bus, configured with three doors and two staircases for smoother boarding and alighting.
These buses were procured under Contract PT342 (Procurement of 3-Door Euro 6 Double Deck Diesel Buses) for ~S$30 million. In total, 100 three-door diesel buses were procured, with Alexander Dennis fulfilling the other half of orders with its 50 Enviro500 (3-door) buses. Both bus types were initially expected to enter revenue service in 2020 (subject to delays).
This is the sixth batch of MAN A95 (or MAN ND323F) buses supplied for Singapore’s public bus industry. Check out the main article: MAN A95 for more background information on the bus model.
Prior to the introduction of these buses, a one-off MAN A95 (3-Door) Concept Bus was commissioned by the LTA. Bearing the registration plate SG5999Z, it was first exhibited to the public in March 2016, and has undergone revenue service trials with Tower Transit (Mar—Sep 2017) and SBS Transit (Apr 2018—Present).

Specifications
Contract PT342 (Procurement of 3-Door Euro 6 Double Deck Diesel Buses) was put up by the Land Transport Authority (LTA) on 15 May 2018 and awarded on 25 April 2019. Alexander Dennis and ST Engineering Land Systems would deliver 50 buses each, namely the Alexander Dennis Enviro500 and the MAN A95 (Euro 6).
Tender specifications for the three-door double-deck bus call for one entrance and two exit doors and the rearmost exit door must be behind the rear axle. In addition, the bus has two staircases and built in a fully-low-floor design. Buses are also limited to a maximum length of 12.5 metres. These buses are also Euro 6 (or Euro VI)-compliant, representing the latest in emission standards which came into effect since 1 January 2018 for all new diesel vehicles registered in Singapore.
According to initial sightings in November 2020, the second staircase of the 3-door MAN A95 is located on the right side of the bus, with side- and rear-facing seats on the upper deck to accommodate this layout. The rear overhang has also been lengthened to accommodate the third door, which appears to be a single-leaf door. The existing wheelbase remains identical to the 12-metre MAN A95; in contrast, the wheelbase of the 12.8-metre MAN A95 (3-Door) Concept Bus was manually extended by welding extension bars in the middle.
Existing LTA requirements for new buses include two wheelchair bays; a Passenger Information Display System (PIDS) comprising LED text displays, LCD display screens and interior speakers; Advanced Driver Assistance System and Anti-Fatigue system; high-definition CCTV cameras; and automatic passenger counters at entrance and exit doors of the bus.
Transition to clean energy bus fleet
The 100 three-door double-deck buses under Contract PT342 are the last pure-diesel buses to be procured for the Singapore public bus industry.
Authorities announced during the Committee of Supply Debate 2019 that Singapore would commit to a 100% clean energy bus fleet by 2040. This commitment was further reaffirmed in the Committee of Supply Debate 2020 held in March, where it was announced that only electric or hybrid buses would henceforth be procured in line with this clean energy goal.
Design Challenges
Prior to this tender, European bus manufacturers typically made fully-low-floor chassis for the left-hand-drive (LHD) market, such as in Europe where similar 3-door, fully-low-floor buses are operated. Given that the tender called for a right-hand-drive (RHD), full-low-floor diesel bus with a third door at the rear overhang, it was a challenge for bus manufacturers to modify their existing designs to deliver this (relatively) small batch of buses to LTA in the most economical way.
The rear alighting staircase on the 3-door MAN A95 (Euro 6) buses faces the rear end of the bus. It is believed that feedback from the revenue service trial of the MAN A95 (3-Door) Concept Bus (SG5999Z) was unfavourable with regards to the safety of the front-facing alighting staircase, which put passengers at risk of falling forwards when the bus had to brake suddenly. A retractable barrier was retrofitted after its debut, which prevents upper deck commuters from accessing the rear staircase when the bus is in motion, and only opens when the bus is at a stop.
Under exemptions to existing Road Traffic rules, the 3-door buses under Contract PT342 are allowed to be longer than 12 m (max. 12.5 m), have a longer vehicle rear overhang (>60% of wheelbase allowed), have a greater turning circle (>19 m diameter), and have passenger doors narrower than 1.2m width (likely for the third door only).
Exemption for 3-door Omnibus (Click to expand)- 6(1) – The overall length of a motor vehicle, other than an articulated vehicle, shall not exceed 12 metres.
- 44(1) – Subject to paragraphs (2) and (3), the overhang of a motor vehicle shall not exceed 60% of the distance between the plane perpendicular to the longitudinal axis of the vehicle which passes through the centre or centres of the front wheel or wheels and the foremost vertical plane from which the overhang is to be measured as defined in rule 2.
44(2) – The Registrar may permit the overhang of a public service vehicle to be more than 60% but less than 65% of the distance referred to in paragraph (1). - 60(1) – Every vehicle shall be so constructed as to be capable of turning in either direction in a circle which does not exceed in diameter 19 metres.
- 77(1)(d) – Other than an emergency exit, every entrance and exit of a vehicle registered on or after 15 February 2006 but before 1 July 2019 as an omnibus shall be at least 1,200 millimetres and shall be fitted with a centre stanchion bar in such manner as the Registrar may specify.
- 77(1)(e) – Other than an emergency exit, every entrance and exit of a vehicle registered on or after 1 July 2019 as an omnibus shall be at least 1,200 millimetres.
