Bahnbetriebswerk Hermeskeil, Railroad museum in Hermeskeil, Germany.

The Bahnbetriebswerk Hermeskeil is a railroad museum housed in a former locomotive workshop with more than 50 preserved locomotives from the early and mid-20th century. The machines are displayed in a six-track roundhouse with a rotating turntable alongside the original depot buildings.

The depot dates from 1888 and was called a Maschinenstation until 1903. From 1956 it was an outstation of Simmern depot, and it was dissolved on 1 April 1959. In 1986 the railway enthusiast Bernd Falz bought the site from the Deutsche Bundesbahn and opened his steam locomotive museum there; he had been collecting locomotives since 1976, starting with a DR V300.

The depot's name changed in 1903 from Maschinenstation to Bahnbetriebswerk, and from 1956 it served as an outstation of the Simmern depot until closure on 1 April 1959. Today the site is run by railway enthusiast Bernd Falz, who bought the grounds from the Deutsche Bundesbahn in 1986; his first locomotive was a DR V300.

The depot stands directly opposite Hermeskeil station, so it can be reached on foot from the platform. The site is a private museum run by collector Bernd Falz, who bought the grounds from the Deutsche Bundesbahn in 1986. Six locomotives are kept under cover in the roundhouse; the rest of the collection stands outdoors on the former depot yard, where paths are unpaved.

The museum preserves rare locomotive series such as the 01, 22, and 41 types that few other facilities display. These machines are especially valuable because they remain with their original workshop buildings intact.
