PURPOSE: A train assembly composed of two or more vehicles with independent steering wheel set travel devices is provided to arrange the independent steering wheel set travel devices accurately in all travel directions by correcting the error of the steering angle, and to prevent collision between the vehicles and the wheel set travel devices by forming an elastic element between the wheel set and the steering rod. CONSTITUTION: A train assembly comprises two or more vehicles(1,2) and three or more independent wheel set travel devices(3,4) besides the steering system. Steering signals are output from the angle position of two adjacent vehicles of the train assembly to the independent wheel set travel devices. The independent wheel set travel devices set the position to the vehicle body. Self-steering of the independent wheel set travel device is performed by connecting a rigid steering unit with self-steering elasticity and combining the self-steering unit with the rigid steering unit.
