The museum is based in a depot which was originally constructed in 1881 for use with the city's horse-drawn trams. The building continued to be used for public transport in the city, moving to electric
trams,
trolleybuses, and later buses until it was closed in 1985. The building was then obtained by the museum, but it was closed in 1994 due to the poor state of the building. The museum reopened in September 2006 after a £1 million restoration. The museum has attracted over 30,000 visitors since its reopening. == Collections ==
