A handhold device of a railcar includes: a frame arranged along a side edge of a specific door opening and connected to a car interior side of a side carshell; a turning mechanism provided at the frame and configured to be turnable about a turning axis extending in an upper-lower direction; and a handle including a base portion connected to the frame through the turning mechanism and a holding portion projecting from the base portion in a direction intersecting with the turning axis. The handle is angularly displaceable about the turning axis between a deployed position where the holding portion is exposed to the specific door opening when viewed from a lateral side of the car body and a storage position where the holding portion is hidden by the side carshell when viewed from the lateral side of the car body.

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.

The invention relates to a rail vehicle. The rail vehicle comprises at least one rail vehicle outer wall. The rail vehicle further comprises a boarding arrangement having at least one first sliding step and one second sliding step. The first sliding step and the second sliding step are mounted so as to be laterally sliding. The first sliding step and the second sliding step can slide from a travel position to an end position by a lateral retraction movement in the direction of the outer wall of the rail vehicle. In the end position, the second sliding step protrudes beyond the first sliding step.
