Radio operation

from Wikipedia, the free encyclopedia

The radio operation (short: FFB) is a train control system for low-traffic branch lines .

It was first built by AEG in 1995 after an accident on the Stubai Valley Railway in Tyrol and approved for operation by the BMVIT . The successor product of the company RDCS has since been in use on three branch lines in Austria.

In the years 1998 to 2000 there were also tests with this system in Germany. As part of the “Haller Willem” Expo project, Siemens Transportation Systems equipped the Osnabrück – Brackwede railway line from Brackwede to Dissen / Bad Rothenfelde accordingly. There were also attempts by Adtranz on the Lautertalbahn between Kaiserslautern and Lauterecken-Grumbach .

System description

The basic idea of ​​the FFB is to relocate the security logic from central interlockings to the vehicles. The vehicle should independently trigger and monitor its route setting via a radio interface . Level crossings must also be activated via a radio link. The relocation of the security logic in the vehicle requires that the vehicle knows its position in the network. For this purpose, a location is provided with passive balises laid in the track , the data of which is then compared with a route atlas stored on the vehicle.

A route is requested from a control center by radio from the vehicle. The control center only issues a driver's license if the route is clear. Access to the control of points and level crossings is also only granted by the control center.

The train integrity must be monitored on the vehicle.

The driver's cab display developed for radio operation at the end of the 1990s “[b] is in a few, insignificant details” corresponded to the ETCS Driver Machine Interface .

It was hoped that the implementation would result in more profitable operation of branch lines by saving interlockings, signals and cabling. However, until 2004 no approval was granted on the “Haller Willem” pilot line. The hoped-for cost savings could not be achieved, in particular the costs for the radio system were underestimated. However, the transfer of costs for safety technology from the line to the vehicle is also problematic in the context of the separation between railway infrastructure companies and railway companies that has existed since the rail reform .
