A bogie includes a bogie frame, a first running wheel and a second running wheel, at least one driving device, a first horizontal wheel, a second horizontal wheel, a first horizontal safety wheel connected to the first horizontal wheel and moving in synchronization with the first horizontal wheel, and a second horizontal safety wheel connected to the second horizontal wheel and moving in synchronization with the second horizontal wheel. The bogie frame has a straddle recess suitable for straddling a rail. The first running wheel and the second running wheel are pivotably mounted onto the bogie frame respectively and are coaxially spaced apart. The at least one driving device is mounted onto the bogie frame and located between the first running wheel and the second running wheel to drive the first running wheel and the second running wheel.
