The Minden Museum Railway (German: Museumseisenbahn Minden) or MEM was founded in 1977 as a society. Its aim was to preserve historic railway vehicles and operate them on the Minden District Railway (Mindener Kreisbahn or MKB). It was not long before the first museum train worked the line. The museum's vehicles were initially housed in the coach hall of the MKB's old locomotive depot (Bahnbetriebswerk) at Minden Stadt station. The museum's trains run on the lines owned by the Minden District Railway and Wittlage District Railway.
