Articulated Buses
Articulated buses were first introduced by Trans-Island Bus Services (TIBS) in 1996. Additional capacity is provided through more seating and standing space in its trailer section. The 1st generation of Mercedes-Benz O405G buses introduced in 1997 had a higher overall capacity than air-conditioned double-deck buses operating at the time.
In 1998 and 1999 respectively, 2 articulated demonstrator units, registered as SBS998Y and SBS999U were operated by SBS/SBS Transit on Bus Services 18, 195 and 290. Both units were subsequently exported to New Zealand in 2006, as double-deck buses were deemed more suitable for SBS Transit bus services at the time.
However, articulated buses made a recurrence under SBS Transit in 2018, when 10 units of the MAN NG363F articulated buses were transferred to the operator under the Seletar Bus Package. All articulated buses under SBS Transit are restricted to operate on feeder bus services within Yishun only.
Tower Transit Singapore also commenced the operation of articulated buses on Bus Service 858, when the operator took over th service in 2021.
