Px29 class steam locomotive at the museum Regular service of Sochaczew County Narrow Gauge Railway ended on 30 November 1984, and the museum was established in December. In the early days all efforts were made to repair, renovate and protect premises, vehicles and to do the necessary repairs of the tracks and vehicles. Preservation and repair works started. Archives and some of the exhibition rooms were placed in the
station main building. Also the sheds for draisines were converted into exhibition rooms. Sporadic train services began in May 1986. The museum was opened to the public on 6 September 1986. By the end of 1986 the museum had collected 107 vehicles, including 33
steam locomotives. In the 1996 this number reached 253. In 2009 the total number of all types of rolling stock was 263, including 56 steam locomotives. After scrapping and selling several units this number fell to 228 in 2011. Some of the vehicles still need substantial restoration before moving from storage to display. In the late 1980s the tracks were repaired, mainly
sleepers replacements but also two bridges were fixed. 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. ==Preserved rolling stock==
