FIELD: machine building.
SUBSTANCE: invention relates to transport machine building. Standard butt pad is equipped with a copper insert as an electric connector, which is placed in the bosom between the rail neck and the strap neck. Configuration of insert, area of adjacency and section are selected so that during joint assembly sufficient conductivity for currents of subway traction system is provided, and insert sustained long-term permissible currents on running rails of subway. Design makes it possible to do without welded electric connectors on running rails of subways and electrified railways.
EFFECT: providing passage of maximum allowable current of traction network of underground.
