The present invention relates to a driving system for a mountain train and a method for controlling its operation, the object of which is to be connected and supported so that a predetermined distance is maintained by a first driving cart unit and a second driving cart unit, while the first driving cart unit is supported in two directions. To provide a driving system for mountain trains and a method of operation thereof, which is operated as and operates in four directions, so that stable driving of the mountain train can be achieved regardless of the inclination angle and the turning angle of the rail. The present invention is connected to the body portion of the mountain train, a chassis frame portion installed in parallel with a pair of slide bars on one side; A first driving cart part which is connected to one side of the chassis frame part, is rotated by two axes by a setter pivot and a pitching pin, and is driven along the rail part by the driving part; A second driving cart unit that is connected and installed to move along a pair of slide bars installed parallel to the other side of the chassis frame unit, is rotated by three axes by a center pivot, a rolling pin, and a pitching axis, and is driven along the rail unit by a driving unit; Including; a connection unit in which one end is rotatably connected to the first driving bogie and the other end is rotatably connected to the second driving bogie; Including, when the bad train is running in an inclined or turning, the first driving bogie As the two-way rotation of the negative and the three-way rotation of the second drive cart part are made, the second drive cart part connected by the first drive cart part and the connection part slides along the slide bar, so that the first drive cart part and the second drive cart part It is configured to be driven by the unit.
