After the decision to switch to diesel traction, the site was completely rebuilt in 1962 to accommodate diesels, including the Warship Class that were used on the Exeter to Waterloo services. The Factory was reformed to provide four roads with servicing pits and cab level platforms, providing facilities to repair eight locomotives at the same time. Access was via the existing traversing table. A daily servicing and fuelling point was built beside the old steam shed and it was this which provided the main facility after the factory closed in 1970.
