The only external body difference was on the final batch of cars where a four character headcode box was fitted above the front cab windows, with the destination indicator on top of a reduced height centre window.
The first cars built, part of an order for 339 Metro-Camm cars, were 4 power/trailer sets for the LMR Manchester area built in early 1957.
One of these was equipped with supercharged Rolls-Royce C6SFLH 230 hp 6-cylinder engines.
The type lasted in service until 1989 when the class was withdrawn.
One car survives, buffet 59575 currently operational at the Great Central Railway.
