Built by Brush Engineering in Loughborough in 1937, the railcars originally worked the Lytham Road route, out of Rigby Road Depot. They were transferred to Bispham Depot in the late 1930s, where they worked the North Station to Fleetwood route with the Pantograph Cars. In the 1960s, they were transferred again to Rigby Road, where they worked the Starr Gate to Fleetwood route. One of Blackpool's most enduring and successful designs, several of the class are still working the tramway today.
