The museum is housed in a former Manchester Corporation Transport bus depot, to the rear of a former electric tram shed on Queens Road, built in 1901.The museum building itself was added later and consists of two distinct halves, a dedicated bus garage completed in 1928, which now serves as the museum entrance area and upper hall, and a lower hall which was created in 1935 by constructing a roof over the open space between the tram shed and the 1928 bus depot.[citation needed] The extensive archive collection is available for research purposes by appointment and includes historic timetables, maps, books, posters, manuals and plans.[9] For most of these events, a heritage bus service from Manchester Victoria station to the museum runs every 20 minutes between 09:50 and 17:00.The museum is open from 10 a.m. to 4.30 p.m. on Wednesdays, Saturdays, Sundays and Public Holidays (except at Christmas and New Year).
