Sunbeam Trolleybus Co
The Sunbeam Trolleybus Co, of Park Lane, Fallings Park, Wolverhampton
Late 1920s: in recognition of future limitations on use of tramways, the Commercial Vehicle Department of the Sunbeam Motor Car Co developed an electric trolley bus design[1]
By 1933 both 4-wheeled and 6-wheeled chassis were made, using BTH electrical engineering and Lockheed brakes, which could be regenerative.
1935 Rootes Group bought Sunbeam. They then brought the bus side of Karrier Motors (which they also owned) from Huddersfield to Moorfield Road so that trolley buses were produced under both names.[2]
1948 Guy Motors acquired Sunbeam Trolley Bus Co from J. Brockhouse and Co except for the tools section which Brockhouse retained[3]. Guy merged their trolleybus-making with that of the Sunbeam company, making the combined operation the largest in the country.
Later a single AEC Regent double-decker with Gardner engine and a Sunbeam radiator grille was developed.
1953 The Sunbeam Trolley Bus Co was formed
1959 Makers of Sunbeam trolleybus chassis.
