Abstract: The present disclosure provides a bogie, a rail vehicle having same, and a rail transport system. The bogie includes: a bogie frame, where the bogie frame has a straddle recess straddling a rail; a first running wheel and a second running wheel, where the first running wheel and the second running wheel are pivotably mounted onto the bogie frame respectively and are coaxially spaced apart; a third running wheel and a fourth running wheel, where the third running wheel and the fourth running wheel are pivotably mounted onto the bogie frame respectively and are coaxially spaced apart; a driving device, where the driving device is located between the first running wheel and the second running wheel, and the first running wheel and the second running wheel are driven by the driving device; and/or the driving device is located between the third running wheel and the fourth running wheel, and the third running wheel and the fourth running wheel are driven by the driving device. The bogie according to this embodiment of the present disclosure facilitates optimization of the structure of an escape passage, and has advantages such as high space utilization, high stability, and strong weight bearing capability.

Abstract: The present disclosure discloses a rail transport system. The rail transport system includes: a rail, the rail includes a steering portion and a travelling portion, the travelling portion is connected to the steering portion, and a first recess is constructed on the travelling portion to form an escape passage; and a rail vehicle, where the rail vehicle includes bogies and a vehicle body, the bogie movably straddles the rail, the bogie fits in with an inner bottom surface of the escape passage of the travelling portion and the steering portion, and the bogie travels by using the travelling portion and is steered by using the steering portion, and the vehicle body is connected to the bogie and pulled by the bogie to travel along the rail. The rail transport system according to this embodiment of the present disclosure has advantages such as facilitation of evacuation of passengers in an emergency, low costs, small occupied space, small rail weight bearing, and high stability.
