The Land Transport Authority (LTA) of Singapore has awarded a S$739.5m ($543m) contract to the China Railway 11 Bureau Group for the design and construction of the Tengah depot.

The Tengah depot will be an integrated rail and bus depot that includes ancillary buildings and a dormitory for transport staff. The depot will be located at a 44.5ha site near Tengah New Town.

It will be the tenth mass rapid transit (MRT) depot in the country. The depot will be used for the maintenance of 100 four-car trains and 600 buses and have other associated maintenance facilities. It will also have a dormitory for transport workers, which will be a four-storey facility with a capacity to house 450 bus captains.

Construction work is slated to start next year and conclude in 2026.

The China Railway 11 Bureau Group has previously completed infrastructure projects in Singapore such as Tuas Link, Tuas West Road and Tuas Crescent MRT stations. It also built the country’s first integrated rail and road viaduct which is part of the Tuas West Extension project.

Last month, LTA awarded PBT Engineering a contract to design and install 5.5km of railway noise barriers along the north-south and east-west lines.

In April, LTA unveiled plans to construct an integrated train testing centre (ITTC) to test the railway systems without disrupting usual MRT services. The centre will be located in a 50ha area at the former Raffles Country Club site.

In January, LTA finalised the alignment and station locations for the first phase of the Cross Island Line (CRL). The underground CRL will connect major hubs such as Jurong Lake District, Punggol Digital District and Changi.
