train wheels on the tracks Here's how it works
Insulated rail joints are an important part of a railway signal control system. Failure of an insulated rail joint is a significant safety issue. As such, railway infrastructure owners take extreme care in maintaining insulated rail joints in good condition. Rail head metal flow/fatigue are failure modes that occur. The effect of this metal flow/fatigue 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 an Insulated Joint slotter is recommended to effectively clear away any metal flow.
