Trolleybuses in Manchester

The trolleybus system in Manchester, England, opened on March 1, 1938, and gradually replaced certain routes of the Manchester tramway network. 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.

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. It closed on December 31, 1966.

Manchester's trolleybuses were also on certain routes jointly operated with the Ashton-under-Lyne trolleybus system, between 1925 and 1966.

Two former Manchester trolleybuses are preserved, one at the Greater Manchester Transport Museum, Cheetham Hill, and another at the Trolleybus Museum in Sandtoft, Lincolnshire.
