Applications

In times of urbanisation, climate change, developing areas, etc., public transport becomes an important alternative to car traffic. As the importance of public transportation grows, so too does the need for greater reliability to ensure the transportation flow 24/7. As passengers make daily use of these modes of transport, comfort and operational excellence are in high demand. IGW ensures reliable rolling stock for great public transportation.

The number of light rail systems is rapidly increasing all over the world. In metropolitan areas they also often complement mass transport systems such as metro. We offer bevel, helical and bevel-helical gear systems in various configurations. Our products can be found in numerous light rail systems all over the world, from high floor to 100% low floor. Underneath you can find some examples:
