FIELD: railway transport; electric traction railways.
SUBSTANCE: invention relates to track circuits and it is designed for passing signal and traction currents on section of railways with electric traction. Proposed rail bond consists of fishplate and resilient current-carrying element installed in space between fishplate and rail necks. Current-carrying element is bent to from one or two end face contact surfaces pointed to side of rail. At least one of said contact surfaces has copper or copper-containing strip. Holes for bolt are provided in current-carrying element which can be made of spring steel.
EFFECT: low contact resistance in bond, provision of reliable passing of signal current with minimum losses.
