Railway vehicle side wall and railway vehicle

The invention relates to the field of railway vehicles, and provides a railway vehicle side wall and a railway vehicle. The railway vehicle side wall comprises a plurality of stand columns arranged side by side and lower edge beam assemblies mounted between every two adjacent stand columns; the side wall lower edge beam assembly comprises a lower cross beam and a side wall lower edge beam connected with the lower cross beam. The side wall lower edge beam comprises a vertical plate extending downwards along the lower side wall of the lower cross beam, an inclined plate formed by obliquely bending the vertical plate towards the side where the lower cross beam is located, and a horizontal plate formed by horizontally extending the end of the inclined plate. The horizontal plate is used for being attached to a chassis boundary beam of a railway vehicle, and the side wall lower boundary beam has corresponding deflection by adjusting the inclination angle of the inclined plate.
