The invention discloses a rail crossing mechanism of a rail car. The rail crossing mechanism comprises a front car body, a rear car body, connecting wheels and hydraulic systems, wherein front wheels are arranged at the front part of the front car body; rear wheels are arranged at the back part of the rear car body; the front car body and the back car body are connected by the connecting wheels, and are both provided with balance frames; the hydraulic systems are respectively arranged in mounting columns of the front wheels, the rear wheels and the connecting wheels, and comprise cylinder bodies and piston bodies; the cylinder bodies are fixed on baseplates of the corresponding car bodies; pistons of the piston bodies are positioned in the cylinder bodies; piston rods of the piston bodies are butted to corresponding beams; oil is between the pistons of the piston bodies and the bottoms of the cylinder bodies; and the adjacent cylinder bodies are communicated by oil pipes. The rail crossing mechanism of the rail car decreases the height difference of the adjacent wheels through the circulation of the oil in several cylinder bodies, so that the whole car body stably crosses through the top end of a crossing rail or an obstacle.
