Rail Insulated Joint Slotting Tool


Insulated rail joints (IRJs) are an important part of a railway signal control system. Failure of an IRJ is a significant safety issue. As such, railway infrastructure owners take extreme care in maintaining IRJs in good condition. Railhead metal flow/fatigue is one failure mode that occurs. The effect of this metal flow is contact between the two rails resulting in critical electrical isolation failure.

To efficiently and safely maintain insulated rail joints to perform as required, the use of a rail insulated joint slotting tool is recommended to effectively clear away any metal flow.
