A carbody of a railcar includes: an underframe; a first member provided at one of vertical sides of a vertical center of the underframe, supported by the underframe, and absorbing collision energy; a second member provided at the other vertical side of the vertical center of the underframe, supported by the underframe, and contacting an obstacle when the first member is compressed by collision with the obstacle. In a case where the second member receives a reaction force from the obstacle when the first member is compressed by the collision with the obstacle, the second member transfers to the underframe a moment load that is opposite in a rotational direction to a moment load transferred to the underframe by the first member.

A traction-impact device including two force transmission elements which extend along a longitudinal axis and which are connected to each other in a force-transmitting manner and an irreversible energy absorption device that includes at least one energy absorption element which at least partially or in regions, preferably completely, includes a fiber composite material. The irreversible energy absorption device is at least partially received by a first of the two force transmission elements. This first force transmission element includes a nozzle portion. The irreversible energy absorption element is arranged in such a manner with respect to the nozzle portion and the other second force transmission element that, when an impact force which exceeds the maximum permissible impact force is introduced into the traction-impact device, the irreversible energy absorption element is pressed through the nozzle portion with at least partial, preferably complete defibration of the regions formed from fiber composite material.
