As Genus I ME designated Royal Saxon State Railways the electrical freight - locomotives of the narrow-gauge railway Klingenthal Sachsenbergstraße-George Thal . In popular parlance , the two locomotives were referred to as lattice trumpets ("Güterrumpel") because of their running noise and their use in front of freight trains .

history

The two locomotives were procured for the route from Klingenthal to Sachsenberg-Georgenthal , which was the only Saxon narrow-gauge railway to be electrified because of its tram-like operation . The electrical equipment was supplied by the Siemens-Schuckert works in Berlin , while the mechanical part was built by the Sächsische Maschinenfabrik in Chemnitz. Shortly before the outbreak of the First World War , the two locomotives were delivered to the Royal Saxon State Railways in July 1914 with the serial numbers 3759 and 3760 and the company numbers 1 and 2.

Initially, the locomotives in Klingenthal were parked unused because the beginning of the war interrupted the construction work on the line. The electrical systems in Klingenthal were not completed until almost three years later, so that the locomotives were first used in front of freight trains on April 20, 1917.

The Deutsche Reichsbahn , founded in 1920, initially continued to use the two locomotives under their old generic name. It was not until 1939 that they were given the new numbers E 191 01 and E 191 02; according to another source, they were not changed until 1948.

The two locomotives handled all goods traffic on the narrow-gauge railway until it was discontinued on April 9, 1963. Operations in passenger train traffic took place only in exceptional cases, for example when the railcars failed.

After the final shutdown of the railway in April 1964, the locomotives were initially parked unused in Klingenthal. In 1967, after several unsuccessful sales attempts, the locomotives were finally transferred to the State Railroad Repair Shop in Dessau , which was responsible for maintenance from 1935 , and scrapped there.

technical features

Mechanical part

The locomotives had a riveted bridge frame made of sectional steel. The driver's cab was arranged in the middle between two porches in which the electrical equipment was located.

The bogies had external frames; each inner axle was driven. The power transmission to the second axle in the bogie took place via Hall cranks and coupling rods. In order to avoid accidents in road traffic, the bogies were subsequently given an all-round cladding into which the two snow clearers were integrated.

As a pulling and pushing device, the locomotives had the funnel coupling common on the Saxon narrow-gauge railways with coupling heads of different lengths.

The locomotives had a Westinghouse brake with an additional brake as braking equipment . The air compressor and main air tank were located in the front end, the auxiliary air tank was attached to the outside of the frame.

Electrical part

The pantograph and main switch were located on the roof of the driver's cab . The pantograph initially had three, later only two contact strips. It was applied with spring force. A spark gap served as a surge arrester .

The drive switch had two switch-on rollers connected in parallel so that both drive motors could also be operated individually. As at that time usual for DC vehicles carried the power adjustment via a series - parallel with Anfahrwiderständen. There were two continuous driving levels.

The two traction motors were designed as direct current series motors in a pin bearing arrangement. They were self-ventilated.
