RAIL TRANSPORT VEHICLE AND CONNECTED TRANSPORT VEHICLES

PROBLEM TO BE SOLVED: To provide a rail transport vehicle and connected transport vehicles, capable of setting up a level of a pulling force strong enough to restrain the idle turning of wheels and also shortening acceleration time, even when the vehicle weight is subjected to a large variation. SOLUTION: A long rail transport vehicle 1 (a standard length rail carrying vehicle 51) is subjected to a large variation in the weight of rails carried thereon, with a resultant large variation in the weight of one vehicle (a variation of about 9 to 12 tons occurs), which requires a level of skillful techniques so as for wheels 4 to travel without turning idle. A control unit 10 detects variable load current I (corresponding to the adhesive mass (weight) of one motive power car) and traveling velocity V so that the number of step N for an engine notch instructed by an operator is restricted so as to fulfill an expression "driving wheel periphery pulling force F
