High-speed switches: safety at ultimate speeds

Successors to the “world-record” switch with new point operating equipment and remote condition monitoring system

Vossloh Switch System has widened the options available for high-speed switches that are already performing a reliable job on a multitude of high-speed networks worldwide. The switches can now be actuated with the track-integrated Easyswitch point operating equipment. Additionally, the remote condition monitoring system SURVAIG NG ensures even greater safety and minimum maintenance input.

Just as on numerous other high-speed networks worldwide, Vossloh Switch Systems supplied all the turnouts for the LGV Est line from Paris to Strasbourg. In April 2007, the TGV achieved on this route a record speed of 578.4 km/h. The “world-record” switch of Vossloh Switch Systems was crossed on this occasion at a speed of 560 km/h. Since then, the company has developed new components for high-speed applications which will be on show at this year's InnoTrans.
Vossloh Switch Systems has, for example, adapted the track-integrated Easyswitch point operating equipment, repeatedly proven in conventional applications, to very high speeds. Easyswitch consists of proven in-sleeper plug & play modules—switch actuation, locking, and position detection units. The installation of the point operating equipment and the replacement of the modules can be completed within a very short time. The standard dimensions of Easyswitch allow, moreover, automatic on-line packing.

SURVAIG NG is a newest-generation maintenance-facilitating remote condition monitoring system which can be integrated into the high-speed switches. This adaptive monitoring system which helps avoid around 70 % of all potential damage, records and analyzes a variety of variables such as the actuating performance of the switch motor, current consumption, track vibration and ambient temperature. It will detect in good time even the slightest irregularities. In this way, SURVAIG NG not only plays a major role in enhancing safety; it also lowers maintenance input and life-cycle costs.
