FIELD: railway transport; permanent way. SUBSTANCE: proposed invention relates to power supply lines with devices arranged along rail bed for electric traction vehicles, i.e. current- carrying devices in places of connection of rails. Track rail bond has fishplates 1 secured by bolts 2 on necks 3 of rails 4 to be butt-joined and current-carrying spring 5. Shape and place of location of spring provide constant and reliable contact between joined rail members owing to increased elasticity of spring and creation of reliable current-carrying circuit. EFFECT: enhanced reliability. 4 cl, 7 dwg
