Abstract (en)

An insulated rail joint uses rail sections having head portion (20A) and a supporting portion (20B) having substantially the same width. The rail sections are terminated with a connection face (30) which extends at an angle to the plane perpendicular to the rail length, and the insulated joint is formed by sandwiching an insulating member between the connection faces. The angled connection between rail sections results in a progressive transfer of force from one rail section to the other as the train passes over the joint. As the rail section has a substantially constant width, connection of the supporting portions of the two rails can achieve secure connection of the rail heads. <IMAGE>
