Signalling and safety systems for railway infrastructure

Signalling systems for railway infrastructure are basis for safe, fast and simple operation of railway traffic and transport. Altpro signalling systems are based on inductive wheel sensing technology. Wheel sensors are entry points for devices and systems which cover wide range of possible applications starting from train detection, section management and axle counting up to complete level crossing protection systems, including driver's indication systems, road signals, (half)barriers and remote control systems.

All ALTPRO signalling systems are certified for safety integrity level (SIL) 4 in independent assessment bodies type A (according to the EN 17020) and tested on EMC and harsh environmental conditions in accredited laboratories.

Safety systems for rolling stock

Safety systems for rolling stock provide additional level of protection for passengers and cargo in railway vehicles, as well as other participants in traffic. Safety systems are designed around the principle of checking the driver's alertness and initiating automatic activities in case the driver's reaction is missing. ATP system, INDUSI based, allerts the driver or automatically brakes the vehicle, depending on the information about vehicle speed, collected during the passage by the signals on railway tracks.

Dead man's system (SIFA) controls the drivers alertness through constant periodical tasks which the driver has to perform, and if the driver fails to do so, warns the driver and in the end automatically stops the vehicle.
