The invention discloses a planing energy-absorbing climb-up prevention device and a railway vehicle. The planing energy-absorbing climb-up prevention device comprises climb-up prevention teeth, a planing pipe, a base and a guiding piece, wherein one end of the planing pipe is rotatably connected with the climb-up prevention teeth; a guiding groove is formed in the planing pipe and is spirally formed in the planing pipe in the axis direction of the planing pipe; the base is connected with the other end of the planing pipe in a sliding manner; a planing cutter is arranged on the base and contacts with the planing pipe, and the planing pipe is cut when impact force reaches a predetermined value; and the guiding piece is clamped in the guiding groove and can be slid along the guiding groove when the impact force reaches the predetermined value. By adopting the planing energy-absorbing climb-up prevention device, the technical problem that a planing energy-absorbing climb-up prevention device in the prior art cannot effectively meet higher requirements on energy absorption capacity of the train is solved.
