The invention discloses a firm railway vehicle base comprising an underframe, fixed frames, wheels, axles, shock absorbers and reinforcing plates. A plurality of the fixed frames are arranged on two opposite sides of the underframe. The wheels are connected to the fixed frames through the axles. The shock absorbers are arranged on two sides of the fixed frame. The reinforcing plates are fixed between the underframe and the fixed frames through welding. According to the invention, the underframe and the fixed frames holding the wheels can be reinforced by welding the reinforcing plates between the underframe and the fixed frames, so that damage caused by deformation of the underframe and the fixed frames holding the wheels when the vehicle base is overloaded is avoided and use inconvenience is avoided. After the reinforcement, the reinforcing plates can share a part of pressure when the vehicle base is overloaded. The load carrying capability of the vehicle base is improved and the vehicle base becomes firmer.
