Mandai Depot (Malay: Depot Mandai; Simplified Chinese: 万礼车厂; Traditional Chinese: 萬禮車廠) is an integrated train and bus depot located in Mandai, Singapore. The train depot will serve as the maintenance and control centre of the Thomson-East Coast line while the bus depot will serve the future Sembawang-Yishun Bus Package.[1]

The facility is located on a 32 ha (79 acres) site [2] bounded by Mandai Road, Seletar Expressway and Lor Lada Hitam, on the former site of Orchidville [3]

The depot is located between Woodlands South station and Springleaf station on the Thomson-East Coast Line and has 3 reception tracks: 1 track Northbound towards Woodlands South station and 2 tracks Southbound towards Springleaf station.


First announced by the Land Transport Authority on 16 June 2011, construction of the depot would commence at the end of 2012 and is expected to be an at-grade depot. The largest orchid farm, Orchidville, was moved on 11 December 2012 to Sungei Tengah, and construction of the depot had begun in January 2013.[4]

The Contract T201 for the construction of Mandai Depot was awarded to Jurong Primewide Pte Ltd at a sum of S$329 million by the Land Transport Authority in October 2013 and construction began in December 2013. [5][6][7]


The depot includes a rail administration building, stabling yards, test track, storage warehouses and maintenance workshops. The administrative building will house the Operation Control Centre (OCC) and Depot Control Centre (DCC) for the Thomson-East Coast line. The stabling yards have a capacity for 90 trains, and stabling capacity supplemented by the East Coast Integrated Depot. The workshops have the capability of servicing and maintaining 11 trains simultaneously.[8] A 66kV substation will be built to support the operation of the TEL.

The bus depot will be situated on the roof of the train stabling yard, and will provide parking and maintenance facilities for at least 550 buses, under the future Sembawang-Yishun Bus Package under the Bus contracting model.[9]
