Originally built as a two-car Class 155 a€?Super Sprinter by British Leyland between 1987 and 1988, using a construction technique similar to that used in the Pacers. Pre-formed panels were riveted together, creating a lightweight body on a welded floor assembly. Powered by a 285hp Cummins NT855-R5 Diesel, working through a Voith Hydraulic transmission, the maximum speed of a Class 153 is 75 mph, making it perfectly suited for small cross-country services
