The application relates to the technical field of railway passenger car modification, in particular to a railway passenger car pillow outer structure. The railway passenger car pillow outer structure comprises a buffer beam, a traction beam, side beams, a cross beam, a longitudinal beam, a dirt box assembly and a footrest; the traction beam is connected perpendicularly with the buffer beam; two side beams are arranged on the two sides of the traction beam in parallel and at intervals, and one end of the side beam is connected with the end of the buffer beam through a footrest coaming; the cross beam is connected between the traction beam and the side beam; the longitudinal beam is connected between the buffer beam and the cross beam; the dirt box assembly is connected with the longitudinal beam; and the footrest is connected with the footrest coaming, wherein the length of the lowest level of the footboard in the footrest is smaller than the length of the upper footboard, so as to form an avoidance for the dirt box assembly. The application can make the original railway passenger car pillow outer structure have a dirt collection function.
