Train Radio protection System (TRPS) is a safety system that quickly alerts dangerous situation to all
trains operating within 2~4km from the alerting position to decrease train speed or to stop the trains.
In the event of alert signal, drivers are required to take appropriate action. If the drivers don’t take any
action within the required time, the train will automatically stop. Shalom Engineering successfully has
supplied TRPS for all locomotives of Korail since 1999
