Track circuit interrupter
open-in-new
<p>A track circuit interrupter may be fitted at <a href="/facts/Catch_points/mpVHc2Jf">catch points, trap points</a> or <a href="/facts/Buffer_stops/jmPyl4bC">buffer stops</a> to maintain a <a href="/facts/Track_circuit/Txl75Un6">track circuit</a> in the 'occupied' state in the event of a derailment. The track circuit remains de-energised until the interrupter is replaced. </p><p>GK/RT0011 specifies the requirements for the provision of track circuit interrupters. </p>
