The invention discloses a railway vehicle and a collision energy absorption structure thereof. The collision energy absorption structure comprises an energy absorption framework and an energy absorption device. The energy absorption framework comprises an airtight wall, window stand columns and bottom edge columns, the two window stand columns and the two bottom edge columns are arranged on the two sides of the airtight wall respectively, the window stand column on each side is connected with the airtight wall and a top frame edge beam of the railway vehicle, and the bottom edge column on each side is connected with the airtight wall and a bottom frame edge beam of the railway vehicle; the energy absorption device is arranged on the airtight wall; wherein the energy absorption device comprises a car coupler energy absorption device and a plurality of anti-creeping energy absorption devices, the car coupler energy absorption device is arranged on the airtight wall, and the multiple anti-creeping energy absorption devices are arranged on the two sides, in the width direction, of the car coupler energy absorption device and the upper side, in the height direction, of the car coupler energy absorption device correspondingly. By means of the anti-creeping energy-absorbing devices arranged on the two sides of the coupler energy-absorbing device in the width direction and the upper side of the coupler energy-absorbing device in the height direction respectively, the energy-absorbing performance of the head of the railway vehicle is improved, so that the collision energy-absorbing requirement of the reconnected railway vehicle is met under the condition that the head is not lengthened.
