No smoking please: The Ruetz power station provided the current for the locomotives of the electric Mittenwald railway.

The first electric standard gauge railway entered operation in autumn 1912: the Mittenwald railway. It connected Innsbruck with the Bavarian community of Mittenwald and extended onwards to Munich. The Ruetz power station, located near Schönberg at the entrance to the valley, provided power for the railway locomotives from 1912 - 1923. It entered an electrical association with the Walchensee power station in Bavaria. To this end, a special international treaty was signed for the first time between Bavaria and Austria.

In the powerhouse of the plant, two machine sets were installed, each consisting of a turbine and a generator. Their output was 6,000 kW, a considerable amount for their time. Between 1920 and 1923, the power station was expanded to include a third, larger machine set and a second high-pressure pipeline. This meant that output could be almost doubled and the ambitious railway-electrification program after World War I could be driven forward. In association with other power stations, the Ruetz power station contributed to supplying power to the Mittenwald and Arlberg railways. It was replaced by the Fulpmes modern underground hydroelectric power plant.

This machine set from the collections of the Technisches Museum Wien (Vienna Technical Museum) was part of the initial equipment of the Ruetz power station. In the smaller of the two casings are the Pelton turbines, and the generator is in the lager casing. The two devices are connected by a shaft. In addition to the turbine casing, you can also see devices for regulating the flow of water. They are activated hydraulically.
