The Eisenbahnmuseum Bochum-Dahlhausen is a railway museum situated south of the city of Bochum in the state of North Rhine-Westphalia, Germany. It was founded by DGEG, the German Railway History Company in 1977 and is based in a locomotive depot that was built between 1916 and 1918 and ceased operation in 1969. Then DGEG took over the whole area of 46,000 square metres and built up the biggest railway museum in Germany. In the middle of the museum, there is an engine shed with fourteen tracks. A preserved turntable, coaling, watering, and sanding facilities are still in operation.
