The Great Western Railway (GWR) 5800 Class was a twenty-strong class of 0-4-2T side tank steam locomotive. These were introduced in 1933 for light branch work. They were similar to the GWR 1400 Class but were not equipped for working autotrains. The entire class was scrapped.
A 5-inch gauge replica of no. 5801 has been built. It works at the Butterley Park Miniature Railway, part of the Swanwick Junction complex.
