East Coast Integrated Depot

The East Coast Integrated Depot (ECID) is a large integrated bus and train depot located in Changi that will serve three Mass Rapid Transit (MRT) lines in Singapore, the East–West Line (EWL), the Downtown Line (DTL) and the Thomson–East Coast Line (TEL). It is currently under construction, with expected completion in 2026.

The depot will be located beside the current site of Changi Depot, which will be demolished. It will be the first MRT depot in Singapore to serve three MRT lines and also the third to be integrated with a bus depot in Singapore after the Tuas Depot on the East–West Line and Gali Batu Depot on the Downtown Line.

With this design, it is estimated that there will be a 44 hectares of land will be saved, equivalent to approximately 60 football fields. The depot will be able to house approximately >200 trains of varying sizes and lengths and >550 buses within the site.

Description
The East Coast Integrated Depot consists of a multi-level train depot and a multi-level bus depot.

Train depot
The train depot will have three levels containing three separate depots for three different MRT lines. The underground portion will house a 66-track depot for the Downtown Line, and will be brought into use following the opening of Stage 3e of the line. The at-grade portion will house a 62-track depot for the future Thomson–East Coast Line, to be used following the completion of Stage 5 of the line. Finally, the elevated portion will house a 72-track depot for the East–West Line, which will replace the existing Changi Depot. All three depots will operate independently of each other, a first for Singapore, and will be designed to be able to handle trains of different lengths, of 3, 4 and 6 respectively of the lines they operate on.

The facility will be located between Simei station and Tanah Merah station on the East–West Line, between Xilin station and Sungei Bedok station on the Downtown Line, and off Sungei Bedok station on the Thomson–East Coast Line. It will also connect to Tanah Merah station on the Thomson–East Coast Line after the Changi Airport Branch is absorbed into the line.

Bus Depot
The bus depot is a separate three-storey structure situated next to the train depot on the same site. Similar to Soon Lee Bus Park and Woodlands Bus Depot, it will contain workshops on the ground level, while the upper two levels will contain parking spaces.
