Barry Railway Class E were 0-6-0T steam tank engines of the Barry Railway in South Wales. They were designed by J. H. Hosgood and built by Hudswell Clarke. The locomotive was designed for light shunting duties at the docks. Their small size made them particularly suited to shunting on the Barry Island breakwater. Access to the breakwater was via a rough hewn tunnel whose dimensions and sharp curves made it impossible for the other locomotives to negotiate a way through.
