Although the use of the AE 6/6 locomotives could be considered to be a complete success since the 1950er â mainly on the Gotthard â there were still some shortcomings: These were mainly due to the lower cornering speed and the lack of multiple control. The use of Re 4/4II in double traction also did not produce the desired results. For this reason, a six-axle locomotive was decided to construct again â in contrast to AE 6/6 but with three two-axis bogies. An important prerequisite for admission after train travel R.. After intensive testing of four prototype machines, a total of 89 locomotives were installed at the Swiss locomotive and machinery factory (SLM) and the company Brown-Boveri & Cie from 1972. (BBC) built in two delivery series. With an hourly output of 7,850 kW and a peak of 140 km/h, Re 6/6 is still one of the strongest locomotives in Switzerland. As with Re 4/4II and Re 4/4III, the exterior of Re 6/6 is characterized by chrome-plated locomotive numbers and letters of ownership and the Swiss coat of arms on the front. All Re 6/6 were decorated with names and coats of arms of places connected to the railway. Soon Re 6/6 had taken over the travel and freight traffic at the Gotthard. Another area of application was the Simplon route between Domodossola and Vallorbe and the Loetschberg. Re 6/6 was quickly found everywhere, whether in individual traction, in multiple control and especially in freight transport, mostly as Re 10/10 together with Re 4/4II or Re 4/4III. Over time, Re 6/6 has received a red coat of paint. Other externally recognizable changes concern the attachment of the UIC socket, the grab handles and the shunting steps. In addition, the two lower round headlamps differed from rectangular headlamp housings. From 2005, most locomotives were equipped with a cab air conditioning system. Today, all remaining machines, called Re 620 and in blue/red paint, are in use at SBB Cargo.This text is machine translated.
