| description | The invention discloses a railway vehicle and a sleeper beam. The sleeper beam at least comprises three cavities, namely a cavity of a first hollow profile, a cavity of a second hollow profile and a middle cavity located between the first hollow profile and the second hollow profile, and the bottom wall of the first hollow profile is provided with an extension section capable of forming the bottom wall of the middle cavity; in this way, the bottom of the hollow cavity can be sealed only by welding the extending section of the first hollow profile to the second hollow profile. Compared with the prior art that the two sides of the lower cover plate are welded to the first hollow sectional material and the second hollow sectional material, the bottom wall of the first hollow sectional material directly extends to form the bottom wall of the middle cavity, only the welding extension section needs to be close to one side of the second hollow sectional material, the welding amount is reduced, deformation of the sle |
