The trolleybus system in Manchester, England, opened on 1 March 1938 (1938-03-01),[1][2] and gradually replaced certain routes of the Manchester tramway network.[3] Manchester was a belated convert to trolleybuses having already started a programme of tram to diesel bus conversion in the mid-1930s and this, overall, continued to be the preferred option for tram conversion that was completed in 1949.[4]
By the standards of the various now defunct trolleybus systems in the United Kingdom, the Manchester system was a large one, with a total of 9 routes, and a maximum fleet of 189 trolleybuses.[2] It closed on 31 December 1966 (1966-12-31).[2][5]
