3-Door Alexander Dennis Enviro500 buses launched on Service 4 & 69

The Alexander Dennis Enviro500 3-Door bus has been launched on SBS Transit Bus Services 4 & 69 on 10 January 2022 and 17 January 2022 respectively.

The bus was also deployed on Bus Service 8 during the evening peak hours on 17 January 2022.

50 units of the Alexander Dennis Enviro500 (3 Door) double-deck bus, configured with three doors and two staircases for smoother boarding and alighting, has been procured by the Land Transport Authority in April 2019, alongside 50 3-door MAN A95 (Euro 6) buses.

These buses are the first to feature a double glass-staircase design on both front and rear staircases, as visible on the right side of the bus.

Complementing the futuristic looks of the bus is a fully low-floor design on the lower-deck, making entering and exiting the bus very accessible.

These buses are the product of engineering efforts by Alexander Dennis Limited after the initial conception in 2016. The engine and drivetrain components had to be relocated to the right rear of the chassis in order for a full-low-floor design.

Registration of these buses began in September 2021, and these buses are currently with SBS Transit & SMRT Buses.

    LTA, please don’t miss the forest for the tree. 3 door bus, double decker or otherwise, is not the main issue. Please focus on green bus apart from the miserable small purchase of pure electric bus many years back.
    3 door feature is also available on green bus, if 3 door feature is the recent craze.
