The locomotive E 178 01 the Deutsche Reichsbahn was an electric locomotive that for the planned electrical transport of long-distance trains on the Berlin light rail has been developed.

history

In connection with the introduction of electrical operation on the Berlin city, ring and suburban railways, the Reichsbahn also intended to transport long-distance trains on the Berlin city railroad with electric locomotives. The aim was to reduce smoke and soot pollution in downtown Berlin. The six locomotives planned for the time being should have a train heating system and the power supply with direct current should be provided by the side busbar planned for the S-Bahn.

The main administration of the Reichsbahn approved the draft of the Reichsbahnzentralamt in August 1928. In addition to the design, the locomotives should have a safety driving circuit and the option of retrofitting pantographs on the roof. The first and only locomotive of this series, completed in early 1929, was supplied by Linke-Hofmann-Busch (vehicle part) and Siemens-Schuckert-Werken (electrical part).

Since the planned operating concept was not implemented, no further machines were built. The single piece was used in the depot of the S-Bahn Friedrichsfelde and Papestrasse. It was shut down on July 1, 1932.

The locomotive was handed over to the RBD Linz in 1943. and relocated to the Hohenfurt-Stift railway depot on the Zartlesdorf – Lipnerschwebe line . Before that, the locomotive was brought to the former Reichsbahn repair shop in Linz for conversion to overhead lines with 1200 V direct current, which, however, could not be completed by the end of the war. The ÖBB had no use for this locomotive and scrapped it there. The intended route was again on the territory of Czechoslovakia after the end of the war.

construction

Mechanical part

The locomotive consisted of two operationally articulated units, both of which were provided with a fireless boiler for train heating, as well as one unit with the driver's cab and the other with a rifle chamber.

The main frame of both units consisted of longitudinal girders stiffened by cross connections, buffer girders and short coupling boxes. The boilers were three-way with a capacity of nine cubic meters. The main air tank and the air compressor were located in low porches on the front sides.

Two of the three wheel sets were driven per unit. The wheel sets had roller bearings, but had no side play. The axes were supported by leaf springs. The driven axles were connected by compensating levers. The drive took place by means of a pawl bearing drive with a one-sided unsprung gear.

Electrical part

Four manually operated pantographs for the side busbar were used to collect electricity. The control switches were electro-pneumatic. The circuit had 22 starting and four continuous speed levels. The four DC motors had an attached fan wheel. At top speed they had an engine speed of 630 rpm. The maximum motor voltage was 750 V. Two motors were always connected in series.
