The invention discloses a railway wagon bogie. The railway wagon bogie comprises axles, swing bolsters, guide frame type side frames, wheels and axle box spring suspension devices, wherein each axle box spring suspension device comprises a rubber blanket, an adapter and a side frame, each rubber blanket is provided with an upper liner plate, a lower liner plate and rubber clamped and fixed between the corresponding upper liner plate and the lower liner plate, each upper liner plate is pressed on the working surface of the corresponding side frame, and the working surface of each adapter is pressed on the corresponding lower liner plate; the upper liner plates and the lower liner plates are all flat plates, and the working surfaces of the side frames and the adapters are all flat faces matched with the flat plates. Under the premise that the bearing capacity is not reduced, the bogie has a lighter weight, and the frictional loss between the wheels and a track can be greatly relieved.
