The London and South Western Railway opened a large Motive Power Depot at Northam in 1840, which remained the principal locomotive servicing facility in the area until 1903 when it was replaced by a new depot at Eastleigh. In 2001, South West Trains chose Northam as the location for the maintenance facility for their new Desiro fleet of trains, which replaced the last slam-door trains to run on the network. The Northam Traincare Facility was constructed by Turner & Townsend and opened in July 2003 by Brian Souter.
