The British Rail Class 119 DMUs were used throughout the Western Region and on services in the Midlands sourced by Tyseley Depot. Built by the Gloucester Railway Carriage & Wagon Co. Ltd, the body design was based on the Swindon Cross-Country sets, but with a Derby cab. Sets were normally formed of three cars.

Shortly after their introduction, some sets were transferred from Cardiff to serve the intermediate stations on outer suburban services from London Paddington to Oxford. These were as 7-car sets, with the addition of Hawksworth composites adapted to run as DMU trailers.

Sets worked over most of the Western Region, notable early use being the last passenger train over the Plympton branch. Minehead, Calne and Bridport branches that have since closed were also served by the sets, which also covered main line services in company with the Swindon Cross Country sets.

As with most asbestos-contaminated stock, there were heavy withdrawals, but a number were rebuilt internally after asbestos removal. 3 cars have been preserved.
