Vale of Neath Railway 4-4-0ST locomotives

The Vale of Neath Railway 4-4-0ST locomotives were nine broad gauge steam locomotives, the first of which entered service in 1851 and the last of which was withdrawn in 1872. The only locomotives on the Vale of Neath Railway in 1851 were the first six bogie tank engines, built by Robert Stephenson and Company as smaller-wheeled versions of Daniel Gooch's South Devon Railway Comet class. Three more with smaller wheels and larger cylinders were added in 1854, but were converted to 0-6-0STs about 1858. The railway was amalgamated into the Great Western Railway in 1865, and the locomotives kept their old numbers.
