NKE Austria GmbH presents its bearings for railway applications. The bearings are used in traction motors and locomotive gearboxes as well as in railcars, trams and underground trains.
Siemens Mobility and ÖBB (Austrian Federal Railways) are digitizing the Austrian rail network to further enhance the attractiveness of public transport. ÖBB is aiming to double the capacity of Austria’s entire rail system by 2040 to cope with increasing passenger numbers. This goal is now a bit closer: The most modern technology for railway operations – the digital European Train Control System ETCS – has now been implemented and commissioned on the 57-kilometer route between Linz and Vöcklabruck. The system controls distances between trains, as well as their direction and speed in real time. This enables the route to carry more passengers and freight, and ensures that the trains run more reliably, punctually, and safely.
Voith Turbo North America has broken ground on a $5 million expansion of its workshop in York, Pa. The expansion will increase the Group Division’s American manufacturing capabilities.
With an innovative technology package from SKF, Ningbo Rail Transit has extended the service life of critical refurbished bearings on eight trainset vehicles from 800,000 to 1 million km. The project is the first commercial application of SKF’s Insight Metro wireless condition monitoring system, which has been developed in China specifically for the needs of the domestic rail sector.
Alpha Trains, the leading locomotive and trains lessor in Europe, has awarded Siemens Mobility a long-term service and maintenance contract. The contract covers the complete maintenance of Vectron locomotives over a period of 15 years, including revisions at the Siemens Rail Service Center in Munich-Allach.

Between now and 2030, a state-of-the-art digital train control system from Siemens Mobility will be installed as an upgrade to the conventional train control system used by operator Hamburger Hochbahn (HOCHBAHN) on its U2 and U4 subway lines. The new technology, known as CBTC (communication-based train control), will allow trains to run at shorter intervals of only 100 seconds, which will put significantly more trains on the track in the future, thereby increasing capacity. In addition, CBTC also improves punctuality, reliability, and energy consumption.
