British Rail Class 416 (2-EPB) was a class of third-rail electric multiple units in service between 1953 and 1995. They were intended for inner suburban passenger services on London's Southern Electric network. There were two subclasses of Class 416: Class 416/1 to an SR design on salvaged 2-NOL underframes, built between 1953 and 1956, and Class 416/2 based on a British Railways Mark 1 coach design. In the 1980s some 2 EPB units were used on the North London Line between Richmond and North Woolwich; these units were equipped with window bars.
