The Flemington Maintenance Depot is the largest Sydney Trains depot, located in the western Sydney suburb of Lidcombe, but named after Flemington further east. 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. 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 K sets. It was also responsible for the S sets and C sets before they were withdrawn. It also maintains the NSW TrainLink V sets.
