A unitary bogie frame for a bogie of a rail vehicle, includes: two side beams and at least one support beam extending in the transverse direction of the bogie frame and rigidly connected to each of the two side beams. The support beam includes a support portion for supporting a drive unit of the bogie and a slender portion. The support portion is directly connected to one of the two side beams and is connected to the other of the two side beams through the slender portion. The planar second moment of area and the polar second moment of area of any cross section of the support portion of the support beam are at least twice as great as the planar second moment of area and the polar second moment of area, respectively, of any cross-section of the slender portion of the support beam.
