Greater Efficiency and Reliability for Graz Linien

Digital Solutions for the Future on Graz's Rails

With its rail vehicle technology, ZF is your reliable partner for the journey into the future on rails. The company is one of the leading technology companies worldwide and delivers systems for the mobility of cars, commercial vehicles as well as industrial technology.

connect@rail combines all intelligent connectivity solutions for the rail transport from ZF. The solutions, monitoring systems and services offer our customers in the rail sector added value in terms of efficiency, cost-effectiveness, reliability and environmental friendliness.

ZF in Graz

After successful pilot and pre-series applications, 10 trams of Graz Linien were equipped with ZF's intelligent Infrastructure and Driveline Monitoring System. Thanks to the ZF technology, vehicle availability in inner-city traffic in Austria's second-biggest city can be planned more efficiently as well as a reliable and low-emission operation is ensured.

In a next step, another 10 vehicles will be equipped with the connect@rail system.

Since December 2020, a tram in ZF design draws attention to the technological and innovative upgrade of the rail vehicles in Graz.

First application: Flat Spot Monitoring

First application: Flat Spot Monitoring

Graz Linien currently focuses on so-called flat spots – uneven wear on the steel tires of the vehicles. The wheel no longer rolls gently over the rail, you can usually hear and feel blows and rumbling while the train is in motion. Thus, passengers and residents alike suffer from noise nuisance.
The hit rate is
100 %
Since the commissioning in Graz, no flat spot has been missed by the ZF system.

Transportation

Mobility is a necessity of modern-day society. Lack of parking space, traffic jams and a pressure to reduce emissions call for a rethink in the choice of transport. If rail transport is to play a greater role in society's mobility mix, trains need to become more efficient to operate and service interruptions need to be eliminated.
