A rail vehicle lighting device includes: a plurality of short lighting fixtures assembled into a long lighting fixture having a shape matching with a shape of an irregular interior decoration. Each of the short lighting fixtures is provided with a section body. A light source is provided on the section body. The section body is twisted such that included angles between each of the light sources and a horizontal plane are consistent. In the rail vehicle lighting device, the plurality of short lighting fixtures is assembled into the long lighting fixture having the shape matching with the shape of the irregular interior decoration, thereby satisfying a requirement on a shape of a lighting fixture. By arranging the twisted section body, respective points of the long lighting fixture have consistent light source illumination angles, thereby achieving a satisfactory illumination effect inside a carriage having an irregular interior decoration, and accordingly improving the appearance of the carriage.

The rail vehicle (1) comprises front end (100) and rear end (102) and side faces (104) and a light strip (3) fixed to the outside of the railway vehicle (1) and comprising a light source. The light strip (104) is fixed on at least either the front end (100) or rear end (102) and on the side faces, and extends over at least 50% the length of each of the side faces (104).
