A unitary bogie frame (14) for a bogie (10) of a rail vehicle, includes: two side beams (24) and at least one support beam (28) extending in the transverse direction of the bogie frame (14), rigidly connected to each of the two side beams (24). The support beam (28) includes a support portion (30) for supporting a drive unit (16) of the bogie (10) and a slender portion (32). The support portion (28) is directly connected to one of the two side beams (14) and is connected to the other of the two side beams (14) through the slender portion (32). The planar second moment of area (M) and the polar second moment of area (J) of any cross section of the support portion (30) of the support beam (28) are at least twice as great, preferably at least 2.5 times as great, as the planar second moment of area (M) and the polar second moment of area (J), respectively, of any cross-section of the slender portion (32) of the support beam (28).
