The depot is built in Tai Seng, covering an area of 110,000 square metres, and is bordered by Kim Chuan Road, Upper Paya Lebar Road, Bartley Road East and Hougang Avenue 3. It contains the Circle Line Operations Control Centre, a maintenance facility and stabling areas, and ancillary facilities such as a train wash, paint shop, locomotive workshop, goods lifts, and an automatic storage and retrieval system, the tallest underground automated warehouse system in Singapore.
Accessed from Kim Chuan Road, the depot appears as a basic two-storey structure at surface level, but the main depot floor is fully underground, 800 metres in length, 160 metres in width and 23 metres in height, at a depth of between 18-22 metres below ground level. It is situated between Tai Seng and Bartley station along the CCL, with a total of 4 reception tracks: 2 tracks heading northbound towards Bartley station and 2 track southbound towards Tai Seng station. An additional 2 more reception tracks were built as part of the Downtown Line 3, with 1 track heading eastbound towards Bedok North station and 1 track heading westbound towards Ubi station.
Contract C821 for the initial construction of Kim Chuan Depot was awarded to Hock Lian Seng Infrastructure Ltd at a contract sum of S$297 million.
Downtown Line initial use
Stage 1 of the Downtown Line opened in 2013, and Kim Chuan Depot was used for the launching of trains and major maintenance works until the line connected with its main depot at Gali Batu in 2015. The depot ceased Downtown Line operations for a while, and would be used again in tandem with the Tai Seng Facility Building for Downtown Line operations when Stage 3 of the Downtown Line opened in 2017, with reception tracks leading to the Downtown Line.
By 2025, Kim Chuan Depot would be expanded to almost double its capacity from 70 to 133 trains. The integrated depot will also house a bus depot at surface level for optimised land use.
Kim Chuan Depot maintains C830 and C830C trains operating along the Circle Line, as well as C951 trains Downtown Line.
