The last remaining St Helens trolleybus at the North West Museum of Road Transport, the redeveloped former St Helens Corporation tram depot, Hall Street, October 2008
By the standards of the various now-defunct trolleybus systems in the United Kingdom, the St Helens system was a medium-sized one, with a total of six routes, and a maximum fleet of 66 trolleybuses.[2] It was closed relatively early, on 30 June 1958 (1958-06-30).[1][2] The 16 youngest trolleybuses in the fleet at that time, ones built in 1950–51, were all sold to other systems for further use. Eight Sunbeam vehicles went to South Shields system and eight British United Traction vehicles to Bradford.[1]
