Lokbahnhof Löbau, Railway museum in Löbau, Germany

Maschinenhaus Löbau is a locomotive roundhouse built from 1859 on the plans of Max Maria von Weber, modelled on a larger English building. It stands on the site of the former Bahnbetriebswerk at Löbau station, where an 1847 two-track Heizhaus with its own well, pump and preheating boiler had become too small. The roundhouse now belongs to the Ostsächsische Eisenbahnfreunde and serves as a railway museum.

Löbau gained its first rail link in December 1846, when the Sächsisch-Schlesische Eisenbahngesellschaft opened the Dresden–Görlitz line and the town received a small locomotive shed with a water well. The present Maschinenhaus was built from 1859 to plans by Max Maria von Weber, after the extension toward Reichenberg made the old shed insufficient; damaged vehicles were already being sent to the new workshop in December 1859.

The site is run by the Ostsächsische Eisenbahnfreunde (OSEF), a railway heritage association that owns and operates the museum in the former Bahnbetriebswerk. Its collection keeps Saxon steam-era locomotives and rolling stock in working order, and the roundhouse setting lets visitors see where locomotives were serviced. The name Maschinenhaus refers to the engine house itself, built for the Löbau locomotive depot.

The site is centrally located in Löbau and within walking distance from the town center. Visitors should note that access may be limited to certain areas or times, so checking ahead is recommended.

The roundhouse was built to plans by Max Maria von Weber, a finance official in the Dresden railway directorate, who modelled it on a larger engine house in England. A wagon shed of the Löbau–Zittau railway had to be moved to the end of the terminal tracks to clear the site.
