A running gear frame for a rail vehicle, comprising a frame body. The frame body comprises two longitudinal beams and a transverse beam unit providing a structural connection between the longitudinal beams, such that a substantially H-shaped configuration is formed. Each longitudinal beam has a free end section forming a primary suspension interface. Each longitudinal beam has a pivot interface section associated to the free end section and forming a pivot interface for a pivot arm. Each longitudinal beam has an angled section associated to the free end section, the angled section being arranged such that the free end section forms a pillar section. The pivot interface section is integrated into to the angled section and the frame body is formed as a monolithically cast component made of a grey cast iron material.
