500mm Feldbahnprojekt, Field railway museum in Treptow-Köpenick, Germany

The 500mm Feldbahnprojekt is a museum field railway in the FEZ leisure centre in Oberschöneweide, in the eastern part of Berlin's Volkspark Wuhlheide. Its 500 mm track links Eichgestell station on the Berlin Parkeisenbahn with the FEZ playground, and the line grew to about 1.9 km with 25 points and five intermediate stops. A grey riveted diesel locomotive with a red chassis pulls open wooden bench wagons past a building signed "Dachrestaurant".

The project was founded in 1991 after acquiring a locomotive from a Berlin brick factory and developed into a working railway with multiple stations. It preserves equipment that originated from historical mining and industrial railways.

The name references the field railway tradition that was common across German industrial regions for moving goods and materials. Visitors can observe how these compact railways were woven into the daily operations of mining and manufacturing sites.

Entry is free and the site is accessible during the opening hours of the adjacent FEZ leisure center, located right at Eichgestell station. Visitors should expect flat pathways and wear sturdy shoes, especially if the ground is wet.

All tracks of the 500mm Feldbahnprojekt lie inside the loop of the Wuhlheide Parkeisenbahn, which itself uses 600 mm gauge. The collection also holds about 150 tipping wagons and tubs, plus a petrol pump built around 1910, brick moulds and several types of switch.
