Track Circuit - Accidents - Broken Rails

Broken Rails

Track circuits can detect some but not all broken rails. If there is only one relay at a turnout, part of the wiring of a turnout is bound to be in parallel, which is not protected from broken rails. If there are two relays at that turnout, then all parts of the wiring can be in series, protecting against broken rails. Thus:

  • Weyauwega derailment (1996) - undetected broken rail in turnout.
