The present invention relates to a control circuit for a pantograph of a train, and more specifically, relates to a control circuit allowing a pantograph to be uniformly used in accordance with the driving direction of the train. According to an embodiment of the present invention, in the control circuit for the pantograph of the train, a pantograph trip relay b contact point and an emergency ground switch (EGS) are sequentially connected to rear ends of two pantograph selection relay a contact points (PANSR1a, PANSR2a) connected with a direction current (DC) line in parallel, and pantograph elevation magnetic valves (PANMV1, PANMV2) branched from the emergent ground switch (EGS) are connected through the pantograph selection relay a contact points (PANSR1a, PANSR2a). The DC power line is connected to a pantograph trip relay a contact point (PANTRa) and is connected to pantograph descent magnetic valves (TRIP1, TRIP2) branched from the pantograph trip relay a contact point (PANTRa). Pantograph pressure switch relay a contact points (PANPSR2a, PANPSR1a) are connected to the DC power line through respective contact point (PANTRa) to be connected to the front ends of the pantograph descent magnetic valves (TRIP1, TRIP2).
