The Minnesota Transportation Museum (MTM, reporting mark MNTX) is a transport museum in Saint Paul, Minnesota. The 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. The 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-1960s. In 2004–2005, the organization's streetcar operations became the Minnesota Streetcar Museum. In addition, a steamboat that was originally built by TCRT in a style similar to its streetcars became the Museum of Lake Minnetonka.
