Russian Power Package to Receive Voith Gear Units

Russian Railways (RZD), currently Russia's largest rail operator, is investing heavily in the modernization of its fleet. Series EP20, a six-axle electric locomotive, has been built in Russia since 2011. Voith is now delivering 804 gear units for 134 locomotives of this type.
The EP20 is one of the most powerful mainline locomotives in Europe. The locomotive has three bogies with two driven axles each. The maximum output of the loco is 7.2 MW, which corresponds to the power of about 100 cars. A major criterion for the Russian manufacturer Transmashholding was that the transmission would be able to cope with the high axle loads of 22.5 tons as well as the extreme weather conditions.

Temperatures of minus 50 to plus 55 degrees centigrade make heavy demands on the drive units of the locomotive. The newly developed SEH-525 gear unit from Voith, a fully suspended single stage helical gear unit with a hollow output shaft, is the ideal solution for these conditions. From 2014 Voith will be delivering twelve gear units to Russia every month.

Russian Railways will put a total of 200 new EP20 locomotives into service. The first ones are already in operation on the route between Moscow and St. Petersburg with maximum speeds of up to 200 km/h. Visitors to the 2014 Olympic Winter Games will also benefit from this modern rail power package when they are on their way to Sotschi.

Voith sets standards in the markets energy, oil & gas, paper, raw materials and transportation & automotive. Founded in 1867, Voith employs almost 42 000 people, generates €5.7 billion in sales, operates in about 50 countries around the world and is today one of the biggest family-owned companies in Europe.
