PKP - Poland
Open Air Railway Museum in Chabówka. Lots of interesting (mainly steam) locomotives, but unfortunately much lack of maintenance.

640 narrow gauge locomotives of type Las (Forest) were built by Fablok from 1958. However, the locomotive in the picture was used in iron ore mines in Southern Poland until 1992.
