At a press conference held in Linz, Siemens Mobility and ÖBB-Infrastruktur AG presented a framework agreement for a long cooperation and announced the successful commissioning of a first route section.

The agreement regulates the expansion of the ETCS Level 2 system throughout Austria’s high-level rail network, the establishment of so-called ETCS Radio Block Centers or RBCs, which will be redundant, and the maintenance and servicing of these facilities.
During the project’s rollout, plans call for installing a total of 21 RBCs by 2038 to provide fail-safe coverage for Austria’s high-level rail network.
ETCS Level 2 operation began at the start of August on the Linz–Wels–Vöcklabruck and Wels–Haiding line sections, marking the first commissioning based on the new framework agreement.
The ETCS Radio Block Center covering this section is located in Vienna, and trains operating on the route are digitally monitored and controlled in Linz.
With ETCS Level 2, data is transmitted from the ETCS Radio Block Center to trains via GSM-R train radio.
Data balises in the tracks are used to determine a train’s position and relay unalterable route data. The corresponding interlocking transmits track vacancy data and other information to the RBC.
The RBC then generates the driving permit and sends it to the train.
This continuous bidirectional flow of data considerably increases the line throughput. Driving trains with this “electronic vision” through several track blocks allows shorter headways at maximum speeds.
ETCS thus provides the basis for autonomous driving at optimum speed. This, in turn, saves energy and protects the environment.
Without ETCS, long distances must be maintained between trains because of their lengthy braking distances.
Thanks to precise high-tech tracking of the trains and mobile communications, ETCS reduces headways, allowing more passengers and freight to be transported in a shorter time.
These advantages can already be seen on railway lines equipped with ETCS, such as the Vienna–Breclav, Vienna–St. Pölten or Kufstein–Brenner routes.
The system is being continuously expanded, with the goal of equipping all Austrian high-level and main lines with modern ETCS Level 2.
ÖBB-Infrastruktur AG will invest €200 million in the train control system by 2026, and a total of around €900 million has been earmarked in the framework agreement for ETCS and train controls.
As a standard throughout Europe, ETCS will also make cross-border travel much easier, and journeys to international destinations will be more comfortable and shorter.
A significant innovation in the framework agreement is the use of the DS3 platform, which has been employed successfully since November 2020 in a pilot project for the interlocking at the Achau railway station in Lower Austria.
Thanks to this digitization, ÖBB achieves significantly higher cost-effectiveness through lower investment and maintenance costs. ■
