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

The oldest preserved locomotive in Poland, TKb1-1479 was built for the Magdeburg-Halberstadter Eisenbahn in Germay in 1878, as "Berlin 1479". It was in industrial use in Poland until 1970.
