The Minnesota Transportation Museum (MTM, reporting mark MNTX) is a transportation museum in Saint Paul, Minnesota, United States. MTM operates several heritage transportation sites in Minnesota and one in Wisconsin. The museum is actively involved in preserving local railroad, bus and streetcar history. MTM was formed in 1962 to save a streetcar that had been built and operated by Twin City Rapid Transit (TCRT) in Minneapolis–St. Paul. Many of the museum's early members were formerly part of the Minnesota Railfans Association, which had organized railfan trips from the 1940s to the 1960s.
