HSR Train Safety
Russian Railways has begun testing the SOB-400A on-board safety system for the future high-speed rail (HSR) train. Consisting of ten modules and units that are installed directly on trains, the system allows for more accurate train location details based on data it receives from track infrastructure facilities.
The developments created by NIIAS specialists are being tested on board a Sapsan electric train. The system provides accurate data on train coordinates by exchanging information with track infrastructure facilities on two frequencies, which improves the accuracy of inter-train interval monitoring in a high-speed operation mode.
They have installed a prototype of the Russian HSR safety system on the Smolensk — Krasny Bor section. The Sapsan train was temporarily ferried from St. Petersburg to Smolensk in order to test it in the real-world infrastructure.
At the moment, experts are studying the interaction between the two systems. The next step will be testing the full train control system on the new high-speed train, including tests of the automated train control function.
