The invention relates to the field of rail moving loading tests, and particularly discloses a variable load type railway track moving loading vehicle which comprises a mounting frame, a hydraulic unit, a moving unit, a simulation unit and a vibration unit. Four corners of the mounting frame are arranged on sleepers on two sides of two rails; the hydraulic unit is arranged on the bottom wall of the upper portion of the mounting frame, the output end of the hydraulic unit faces downwards, the moving unit comprises a moving guide rail, the moving guide rail is vertically arranged on the mounting frame in a sliding mode and connected with the output end of the hydraulic unit, the simulation unit can move on the moving guide rail, the simulation unit comprises two lower wheels, and the lower wheels make contact with the rails. The vibration unit is arranged on the moving unit, the vibration unit can be in contact with the simulation unit, and the vibration unit can generate vibration. The invention aims to provide the variable load type railway track mobile loading vehicle so as to solve the technical problem of high cost of an existing dynamic load vehicle.
