The end wall includes a doorway for providing access to the usable space, and at least two footplate catchers for preventing a set of footplates arranged adjacent to the footplate catcher from entering the usable space, such as in an event of a crash. ## Claims ### Claim 1 A rail vehicle, comprising: a carbody shell, the carbody shell having an end wall and a usable space, said end wall comprising a doorway for providing access to said usable space, said doorway comprising lateral walls and a threshold with one or more footplates, wherein said end wall further comprises at least two footplate catchers located laterally at a distance from each other, each laterally outside said threshold, for preventing the one or more footplates having a footplate width greater than (A) a threshold width and (B) the distance between the at least two footplate catchers from entering the usable space. ### Claim 2 (depends on 1) The rail vehicle according to claim 1, wherein the end wall further comprises a substantially horizontal recess provided at the bottom of the doorway, said recess having a recess width greater than the footplate width of the set of one or more footplates. ### Claim 3 (depends on 2) The rail vehicle according to claim 2, wherein the recess comprises at least two notches located at least partially at two opposite bottom corners of the doorway. ### Claim 4 (depends on 3) The rail vehicle according to claim 3, wherein at least one of the footplate catchers comprises at least one retainer for stopping and/or holding at least one loose footplate from the set of one or more footplates, the retainer being arranged at least partially within the recess. ### Claim 5 (depends on 4) The rail vehicle according to claim 4, wherein at least one of the footplate catchers comprises two retainers, each retainer being located on either side of the doorway, wherein the retainers are located at least partially within a transverse span of the footplates. ### Claim 6 (depends on 5) The rail vehicle according to claim 5, wherein the retainers are located outside a passage through the gangway. ### Claim 7 (depends on 6) The rail vehicle according to claim 6, wherein the retainers are located beyond an inner lining of the gangway, in a transverse direction, rendering the footplate catcher invisible to the passengers. ### Claim 8 (depends on 7) The rail vehicle according to claim 7, wherein the retainers comprise a curved plate connected to the carbody shell, in particular to the end wall. ### Claim 9 (depends on 8) The rail vehicle according to claim 8, wherein the retainers are provided with a stop, a first leg and a second leg, the first leg extending from the stop in a direction upwards, the second leg extending from the stop in a direction downwards, at least one leg having its extremity connected to the carbody shell. ### Claim 10 (depends on 7) The rail vehicle according to claim 7, wherein the retainer provides an indentation for receiving the at least one loose footplate. ### Claim 11 (depends on 9) The rail vehicle according to claim 9, wherein the retainer is substantially S-shaped. ### Claim 12 A set of rail vehicles comprising at least two rail vehicles and a gangway arranged between said two rail vehicles, at least one of said rail vehicles comprising: a carbody shell, the carbody shell having an end wall and a usable space, said end wall comprising a doorway for providing access to said usable space, said doorway comprising lateral walls and a threshold with one or more footplates, wherein said end wall further comprises at least two footplate catchers located laterally at a distance from each other, each laterally outside said threshold, for preventing a set of one or more footplates having a footplate width greater than (A) a threshold width and (B) the distance between the at least two footplate catchers from entering the usable space, wherein the gangway comprises at least one footplate, and wherein at least one of the footplate catchers is located on a path of a loose footplate and is operative to prevent said loose footplate from entering said usable space in an event of a collision. ### Claim 13 (depends on 12) The set of rail vehicles according to claim 12, wherein the set of rail vehicles is provided with pairs of footplate catchers opposing each other in the longitudinal direction.
