FIELD: railway transport; permanent way.
SUBSTANCE: invention relates to switch position control means. Proposed electric drive has housing with electric motor provided with cover, automatic selector and wear-resistant self-lubricating mechanical group. Said group includes cylindrical rack made of anticorrosive material and tie-rods facetless in cross section. Drive is provided with cover opening warning system. Holes for rack and tie-rods are made with cylindrical and mating forms in bushings installed in housing. Housing and/or housing cover are lined with hydroscopic material from inside. Cover lock is of combination design. Bushings of rack and tie-rods can be arranged in plate installed in housing window.
EFFECT: reduced cost of maintenance and repair of electric drive.
