Built at a cost £31m, it was constructed on a long, narrow strip of land previously the site of overgrown railway sidings. The depot is responsible for West Midland Trains' Class 350 Desiro fleet which were introduced in June 2005.

For a normal day's operation in 2010, the depot had to prepare 5 Class 321s, 54 Class 350/1s and 27 Class 350/2s.
