D0260, named Lion, was a prototype Type 4 mainline diesel locomotive built in 1962 by the Birmingham Railway Carriage and Wagon Company, in association with Sulzer and Associated Electrical Industries, at their Smethwick works in Birmingham to demonstrate their wares to British Railways. The locomotive’s number was derived from its works number, DEL260.
