As part of the contract to build and maintain the Sydney Trains A sets, John Holland built a depot on the site of the former Clyde Marshalling Yards adjacent to the MainTrain facility.

[1][2][3] It was opened by Minister for Transport John Robertson on 24 July 2010.

[5][6] In February 2017, it was revealed that subsidence had occurred underneath the depot after plastic cells had failed.

[7][8] During 2018, maintenance of the Sydney Trains M set fleet was moved to Auburn from Eveleigh Railway Workshops.

[citation needed] The maintenance centre building has seven roads.
