The present invention provides a model steam locomotive running on a rail, comprising: a frame where a vehicle composed of a cap, a boiler room, or a passenger car is placed on an upper surface thereof; a pick-up member installed in a lower portion of the frame, wherein an axle is constrainedly fitted to a bearing installed in the center; wheels fitted to both side ends of the axle; an electrical connection port embedded in the pick-up member while being in contact with an outer ring of the bearing; and a main PCB connected to the electrical connection port through an electrical wire. A current supplied to the rail is supplied to the main PCB through the wheels, the axle, the bearing, the electrical connection port, and the wire; thus enabling a forward movement and a backward movement, and the speed to be controlled through the main PCB. |
