Pantograph test run of new Aem 940 # 002 and # 004 in multiple traction on the Thurtal main line between Erlen and Oberaach. No "Pininfarina" design, but reduced to form follows function. The SBB ordered 47 of this PRIMA H4 bi-mode locomotives from Alstom in 2015. They are powered by an electric traction system and diesel generators. The two power generators, coupled with an automatic start-stop system, enable a 5% reduction in fuel consumption compared with a single engine diesel locomotive. Maximum velocity is 120 km/h, weight 84 tons, power from overhead wire maximum 2000 kW and with both diesel motors 900 kW. It will be used in the large shunting yards Limmattal and Lausanne to replace the aged diesel Am 6/6 and electric Ee 6/6 II, and for track work trains of SBB infrastructure.
