The invention discloses a partition wall. The partition wall comprises a lower support, an energy absorption support and an upper support; the lower support is of a hollow structure or a solid structure; the energy absorption support is fixedly arranged on the lower support, is of a solid structure, and is used for fixing an energy absorption structure; the upper support is fixedly arranged on the energy absorption support, and is of a hollow structure or a solid structure. Through the design, the needed severity can be met, vibration attenuation and energy absorption can be achieved, and noise outside a carriage can be blocked. Through the arrangement, the energy absorption support has the good severity and the good strength, and therefore the overall vehicle safety performance is effectively improved; meanwhile, as the lower support and the upper support can be arranged to be of hollow structures, vibration attenuation and energy absorption can be achieved, the self weight can be reduced, the requirement for a light vehicle body is met, and the material cost is saved. The partition wall formed by combination and fixation is fewer in welding line and neat, automation welding can be achieved, the good process performance is achieved, the partition wall can be combined with the stream-line outer surface of the vehicle body, and the sealing effect is better. On this basis, the invention further discloses a track vehicle with the railway wall.
