DEVELOPMENT OF A LONG LIFE INSULATED RAIL JOINT

Insulated rail joints used at the end of a track circuit are required to have enough mechanical strength against the train axle load or the thermal pressure of rail, besides the property of electric isolation. In spite of many studies to improve the mechanical strength of insulated rail joints and to decrease the breakdown of joints that causes traffic interruptions, the results were not fully satisfactory so far. Recently, JNR constructed the testing installations for insulated rail joints. With the installations, studies were carried out to extend the life of the built-up type insulated rail joints and an improved joint which has a life more than twice that of present joints was obtained.
