Vehicle type:
Registration country:
1969
In 1969, the Swiss Federal Railways (SBB CFF FFS)
commissioned the development and manufacture of a new
Bo’Bo’Bo’-locomotive. It had to be the faster and more powerful
than its predecessor: the Ae 6/6
electric locomotive.
The new locomotive is built by the Schweizerische Lokomotiv- und Maschinenfabrik (SLM, now part of Stadler Rail) and Brown, Boveri & Cie (BBC, now part of ABB).
At the time, the main requirements were that the locomotive had to be able to pull a 800 tonnes train, at a constant speed of 80 km/h, up a slope of a maximum of 26 per mille. The locomotive also had to be able to round the tight 300-meter curves over the Gotthard pass with a speed of at least 80 km/h.
These requirements resulted in a design with three two-axle bogies, with one traction motor per axle. The Re 6/6 power rating is impressive: 7.850 kW at 100 km/h.
4x prototypes are initially built:
- Re 6/6 11601 – 11602 with a 2-part articulated body, interconnected by hinges;
- Re 6/6 11603 – 11604 a uniform body, a more simple and cheaper solution.
