Abstract: The present invention relates to a bogie structure for a mountain railway car. The bogie structure is configured as follows: a traction motor for driving an axle of mountain railway car is installed on a car body to simplify the bogie structure and to minimized interference between the traction motor and other components constituting the bogie, and a first and a second bearing are respectively inserted and installed between a first and a second axle and a first and a second wheel, so that a first and a second wheel located in one side close to a turning center are rotated less than a first and a second wheel located in the other side opposite thereof and a traveling distance of the wheels located in the turning-centered side is generated corresponding to a length of a turning-centered side railway, whereby the mountain railway car is improved in traveling stability.
