The original locomotive works and drawing offices of the TVR were located in the West Yard of Cardiff Docks, co-located there so that use could be made of the local boiler makers skills.
They hence sold off the business and leased the site to the Pullman Company Ltd, who maintained their own carriages along with some private owner wagons and BR stock.
[1] Located on the southside of the tracks to the carriage and wagon works, parallel to Colum Road, it was the largest railway depot on the TVR.
The GWR had supplied a standard-pattern over-grider 55 feet (17 m) pattern railway turntable, which was never extended as it could cope with the tank engines allocated to the site.
