SBB Re 4/4 Elektrolokomotive | Lok Nr.10001

The Re 4/4 was an electric express train locomotive built from 1946  for the SBB. The Re 4/4 were the first bogie locomotives of the SBB and thanks to their low axle load of only 14t were able to drive higher cornering speeds. Their specifications included the management of express trains on the east-west transversal from Geneva to St. Gallen. The contract for the construction of the locomotives went to the Swiss locomotive industry with SLM for the mechanical part and assembly and MFO for the electrical part. BBC and Secheron supplied traction motors and transformers. The locomotives were built in 2 variants.

The first 20 machines 10001-10026 were designed for use as locomotives for shuttle trains they could be lined up in a train between the cars or at the end of the train and also had a door at the front with the option to transition to the cars through the machine. They had an electric brake and multiple controls. The locomotives were also easy to recognize by the distinctive fan grilles.

The second 20 machines 10027-10050 had no electric brakes and were not suitable for remote control. In the second phase of their service life these locomotives were also used in highly qualified passenger train traffic (TEE Rheingold TEE Bavaria) and on the other hand in regional train traffic.
