Construction began in 2016, with completion initially scheduled for 2024. However, in 2022, the timeline was adjusted to 2025 due to delays caused by the pandemic. The completion date was subsequently revised again to 2026.
The train depot complex comprises three levels: The Downtown Line depot is located underground, the Thomson-East Coast Line depot is on the ground level, and the East-West Line depot is on the level above.
The three depots are designed to operate independently of one another.
“Careful planning has been done for the three depots to share the same layout so that MRT lines with different numbers of train cars can be stacked on top of one another,” said LTA.
To facilitate the connection of tracks between the East-West Line and integrated depot, train services between Tanah Merah and Tampines MRT stations will be suspended from Dec 7 to Dec 10.
The three-storey bus depot, which can charge around 240 electric buses, is located next to the train depot.
LTA said in 2022 that the bus depot would be able to hold up to 760 buses, but later revised the figure to “over 500”.
The integrated depot is one of several large-scale depot projects set to open in Singapore by the end of the decade.
The Sengkang West multi-storey bus depot, which begins operation early next year, is set to support the large-scale deployment of electric buses. Another multi-storey bus depot, built along Yishun Avenue 8, is slated to open in 2029.
