History
Steam

Cardiff Canton was opened in June 1882 as a six road, -long shed, built to replace Long Dyke, east of
Cardiff General station. The GWR enlarged the depot in 1897 with a -diameter turntable installed in a square locomotive shed with 28 roads radiating of off the turntable. In 1925 the GWR added a locomotive repair and lifting shed and a new coaling stage. In 1931 the original -turntable was removed and replaced by a larger -diameter one at the west end of the yard. At this time, around the peak of GWR operation, the depot had allocated 50 main line passenger locomotives, 40 heavy goods/
mineral locomotives and 30 smaller local passenger/goods and shunting locomotives. Steam traction at the depot ceased on 8 September 1962.
