According to the present invention, the locomotive is driven by the running wheels 6 mounted on the running rails 10 both when the locomotive is running on a flat road and when running on a steep curved section. Supports its own weight.

When traveling on a flat road, the driving wheels 8 are pressed against the inner surface of the traveling rail 10 by the traveling mode switching means. In this traveling mode, the locomotive is towed by a small traction force generated through frictional contact between the inner surface of the traveling rail 10 and the drive wheels 8.
Also, such small traction is sufficient.

When the locomotive approaches a curved section or the like on a steep slope, the driving wheels 7 are pressed against the side surface of the driving rail 9 on the side of the web by the driving mode switching means. In this traveling mode, the locomotive is towed by a large traction force generated through frictional contact between both sides of the web of the drive rail 9 and the drive wheels 7, and travels.
