Hougang Bus Depot was built by Singapore Bus Services (SBS), and began operations in 1984, built at the cost of around $13 million and taking over the old Bedok Depot. At 76,838 square metres, Hougang Depot accommodates the parking of up to 546 buses (recorded as 74,236 sq m in 2017). Situated in an industrial area along Defu Avenue 1, it is far from residential areas, ensuring that the early morning and late night bus activity does not disturb residents. As a major bus depot serving the northeast of Singapore, it provides maintenance and refuelling facilities for buses in the area. It is commonly referred to as HGDEP.

The depot is also home to Comfort DelGro Engineering (CDGE)’s bus assembly facility. The bus assembly facility started off with SBS in 1977 or 1979 at McKenzie Road Depot, assembling Leyland Atlantean buses from complete knock-down (CKD) kits. The facility shifted to Woodlands Depot (SBS) in 1983, and finally settling in Hougang Depot on 1 Dec 1994. 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 holds the land tenure lasting 38 years from 1 January 1983.

Currently, the majority of SBS Transit driver training takes place here. As such, Training Buses are frequently sighted within the depot and making their rounds in the surrounding areas.


To make way for the construction of the Kim Chuan Depot Extension, Hougang Bus Depot was expanded towards the North and East to compensate for lost parking space at the South end of the depot. Modification work to Hougang Bus Depot was completed in late 2017.

Contract 8813 for Modifications to Existing Hougang Bus Depot was awarded to Quek & Quek Civil Engineering Pte Ltd for S$21.4 million in June 2016.

    I think Hgdep no more base for training as I’ve seen many training buses all over SBST depots.
