The museum's headquarters are that of the former Sochaczew County Narrow Gauge Railway (Polish: Sochaczewska Kolej Powiatowa).
It has a fleet of historic 750mm-gauge steam, diesel and electric locomotives, goods wagons, passenger cars and draisines.
Trains from the museum to Kampinos Forest run on Saturdays from the end of May until the mid-September and also on Wednesdays during the summer holidays.
Regular service of Sochaczew County Narrow Gauge Railway ended on 30 November 1984,[1] and the museum was established in December.
On 10 July 1991 the Technical Commission of Narrow Gauge Railways (Polish: Komisja Techniczna z Zarządu Kolei Dojazdowych) granted clearance to operate the line to Wilcze Tułowskie, where the trains now terminate.
