A longitudinal support for a chassis frame of a rail vehicle, comprising:

• a box-shaped first connecting portion disposed in a central portion of the longitudinal support such that said box-shaped first connecting portion is located centrally in relation to a longitudinal direction of the chassis frame, the first connecting portion having an aperture with a partially straight first peripheral edge for connection of a transverse support of the chassis frame, said aperture opening the first connecting portion normal to the longitudinal direction in a transverse direction of the chassis frame;
• wherein the first peripheral edge is configured as four first connecting edges extending straight, said first connecting edges being separated from one another by first recesses, an upper first connecting edge of the four first connecting edges being formed by a top flange of the longitudinal support and a lower first connecting edge of the four first connecting edges being formed by a bottom flange of the longitudinal support.
