Driving networks around the world

For this highly specialized market we provide robust and efficient  systems with a special focus on minimized maintenance and low noise. We have the design capabilities to produce customized products, often working to short lead times. From heavy duty locomotive to light rail applications, from low speed city metros to very high speed trains: IGW is your engineering partner for any transmission solution. 

We have been involved in major rail projects around the world (more than 250), covering trams and metro, plus high speed trains in the People’s Republic of China. Our global presence means our solutions operate in all kinds of environments – from extreme heat in Brazil to the artic conditions of Norway.


  • Housings are as standard, made from high-grade ductile cast iron (aluminum castings are also available).
  • Gears are designed with load optimized correction and profile ground using state of the art grinding technology.
  • Bearings are selected for railway applications conforming to specific railway requirements.
  • Couplings for every application in different designs (connection motor to gear unit, or gear unit to axle).
