The Flemington Maintenance Depot is the largest CityRail train depot, located in the western Sydney suburb of Flemington, New South Wales, Australia.
The depot opened in 1927 and was one of four electric train depots built under the Bradfield electrification plan, the other depots being at Mortdale, Hornsby and Punchbowl (later closed).[1] The depot features 20 storage roads, 10 of which are under the main shed, a lift shop, wheel lathe and a train washing facility. The depot is responsible for the stabling and maintenance of all C sets, as well as an allocation of L, R&S sets that operate on the Bankstown, Airport and East Hills, Inner West, South, Carlingford Lines and Olympic Park sprint (known as Sector 2). It also maintains the Intercity V sets. Tangara trains that operate on Sector 2 are maintained at Mortdale.
