Placement of the devices at an electric track

Suspension cantilevers and hinged cantilevers of electrified lines should be mounted at a sufficient height so as to allow a wire laying train with its railings up, pass underneath also during shunting operations and when moving over to a dead track. Unambiguous instructions for sections where the railings have to be lowered should be drawn up for the train operators and the persons responsible for the movements of the work units.
