An insulated track circuit interrupter fitted to trap points
A track circuit interrupter may be fitted at catch points, trap points or buffer stops to maintain a track circuit in the 'occupied' state in the event of a derailment. The track circuit remains de-energised until the interrupter is replaced.
GK/RT0011 specifies the requirements for the provision of track circuit interrupters.
