The invention relates to a rail vehicle pantograph enabling circuit which comprises two units symmetrically arranged on a train, each unit comprises a first branch and a second branch. Each first branch comprises a train activation relay normally-closed contact, a train activation relay normally-open contact and a pantograph enabling relay which are connected between train power sources in series,a first terminal of a knife switch of a high-voltage box is connected between the train activation relay normally-closed contact and the train activation relay normally-open contact, and a second terminal of the knife switch of the high-voltage box is connected with a second terminal of a knife switch of a high-voltage box of a first train line opposite side uni. Each second branch comprises a cab activation relay normally open contact, an enabling bypass switch and a pantograph enabling relay which are connected in series between train power supplies. The upstream ends of the pantograph enabling relays of the two units are connected through a second train line. The pantograph enabling circuit of the railway vehicle can guarantee effective output of pantograph enabling signals.
