SBS Transit

SBS Transit Limited is a multi-modal public transport operator in Singapore, founded in November 2001, although its roots can be traced back to Singapore Bus Service (SBS) which formed in 1973. It runs bus and rail transport services in Singapore, and is a subsidiary of multinational land transport company ComfortDelGro.

Singapore Bus Service (SBS) was initially formed in 1973 with the government-sanctioned merger of three private bus companies, (the Amalgamated Bus Company, Associated Bus Services and United Bus Company), to improve service standards of public buses being the main mode of public transportation back then. It then held a monopoly of all bus services (a duopoly following TIBS’ entry into the market in 1982) and remains as Singapore’s largest bus operator.

In November 2001, the company was renamed SBS Transit after formally became a multi-modal transport operator, taking over the North East MRT Line while preserving its SBS namesake familiar to many. It also operates the Sengkang & Punggol LRT Lines and the Downtown MRT Line.


SBS Transit is the largest bus operator in Singapore, running some 250 bus services with a fleet of more than 3,200 buses (prior to the Government Contracting Model). The fleet comprises mostly Volvo B9TL double-deck buses, along with Scania K230UB and Mercedes-Benz Citaro single-deck buses, operated from bus depots around the island.

The company also assembles its own buses at its Bus Assembly facility at Hougang Depot under the engineering branch of its parent company, Comfort DelGro Engineering (CDGE). All locally-assembled buses done by CDGE (for SBS) are produced here, including SBS’ Volvo Olympians, Super Olympians, Dennis Tridents and SBS Transit’s Volvo B9TL CDGEs & Wrights.

SBS Transit entered the rail scene on 20 June 2003 as the operator of the North East Line (NEL). The operating license was offered to SBS Transit to foster competition with SMRT Trains, and operates on C751A and C751C trains. They are painted in glossy black and white base colors, with red and purple stripes. It also operates the Sengkang & Punggol LRT lines out of the same depot in Sengkang.

The company also took over the Downtown Line from 22 December 2013. Under a new licensing framework, the trains were painted in LTA livery instead.
