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

Passenger tank locomotive TKt48-191 was the last steam locomotive built for PKP by Fablok, in 1957. It is currently undergoing heavy maintenance before returning to the main line.
