FIELD: railway transport.
SUBSTANCE: invention relates to the field of railway transport, in particular to equipment for maintenance and repair of undercarriage equipment and bogies of mobile railway, metro and tram trains, in a depot, and is installed in a depot inspection ditch. The overpass contains a rail track fixed on the support posts by means of rail fasteners providing electrical isolation of the rail from the support post, dielectric elements are installed between the upper supports and the rail track, which provide insulation between the rails and the posts, and the support posts are connected by a single ground bus.
EFFECT: improved conditions for maintenance and repair of undercarriage equipment and wheeled bogies by maintenance personnel in depot conditions, as well as a reduction in the labor intensity of servicing the inspection ditches themselves, ensuring the safety and convenience of personnel servicing the rolling stock.
