Roco presents the re 10/10 series of special events in its anniversary edition to celebrate the 175-year anniversary of the railway in Switzerland. The locomotives in the green SBB paint were covered with decorative strips and coats of arms.The double traction from Re 4/4Ë¡Ë¡ and Re 6/6 is referred to as Re 10/10 for the sake of simplicity. This name is derived from the ten driven axles that have the double tension and does not refer to a locomotive type of its own. Re 10/10 are used by SBB almost exclusively in front of heavy goods trains on the Gotthard line. The strong double creates the prescribed maximum load of 1,400 tons on the towing hook at 80 kilometers per hour on a slope of 26 per mille.This text is machine translated.
