Track construction, renewal and upgrades
The extension and availability of transport lines are becoming increasingly more essential today. We solve the logistical and organizational challenges in new track construction, maintenance and renovation while keeping the route available as much as possible. As a specialist, we can handle all types of track construction from ballasted track to slab track and encompasses all track gauges from standard, to mountain, cable and narrow-gauge railways.
All projects are fully implemented from A to Z – economically, reliably, and rapidly even with non-interrupted service. Our combination of skilled managers, experienced employees, innovation, and cutting edge technology enable us to master all tasks with the utmost precision.
