3-Door Alexander Dennis Enviro500 buses launched on Service 969 & 969A

The Alexander Dennis Enviro500 3-Door bus has been launched recently on Tower Transit Bus Services 965, 969 & 969A in April 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.

All units completed registration in January 2022, with SBS Transit, Tower Transit & SMRT Buses operating 25, 20 & 5 buses respectively.

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.

    I don’t understand why new buses(Majority) must always go to the east (Bedok, Tampines and Pasir Ris)
