The embodiment of the invention provides a rail transit grounding system, which comprises: a train, wherein the train comprises a trailer and a bullet train; a rail, wherein the train is in rolling connection with the rail through a wheel pair, and a grounding carbon brush is arranged at the shaft end of the wheel pair; a first grounding device, wherein the trailer is connected with the groundingcarbon brush through the first grounding device; and a second grounding device, wherein the bullet train is connected with the grounding carbon brush through the second grounding device, and the second grounding device comprises a grounding resistor. According to the invention, the vehicle body backflow is effectively inhibited, the obstruction to overvoltage discharge is reduced, and the bearingdamage rate is reduced.
