In August 1971 the Friends of the Locomotive Society () began operating steam-hauled passenger trains at weekends on the Jokioinen Railway, which at that time was still open for commercial freight traffic. The closure of the railway on 1 April 1974 ended the operation of these trains. An attempt was made to take over the entire line as a heritage railway but this was not possible. The museum was finally established on 2 February 1978, four years after the closure of the commercially-operated railway, when the new Jokioinen Museum Railway Limited
joint stock company () bought the rail line from
Jokioinen railway station to
Minkiö railway station, with its land and associated buildings. Museum steam trains began running on this section on 25 June 1978, and in 1994 the line was extended from Minkiö back to
Humppila. ==Route==
