A combined road/railroad vehicle is provided with a wheel chassis (1a) having front and rear road wheels (2; 3). The vehicle also includes a front, lowerable rail wheel axle (5a) carrying rail wheels (5), and a rear bogie (7) which can be rotated about a vertical axle (8) and which carries rail wheel axles (6a) which, in turn, carry rail wheels (6). The chassis also carries a frame structure which includes a front and a rear frame unit (30; 31) having transverse beam elements (33; 34) which include telescopic beam parts (35; 37) that support at respective ends thereof lifting frame parts (37; 38) which include lifting legs (39, 41; 40, 42) that can be brought into engagement with the underlying supporting surface. The frame structure is rotatable in relation to the chassis, about an axle (44). The vehicle is shifted from a road driving mode to a railroad driving mode, by lifting and laterally moving the vehicle with the aid of each of the rotatable frame units (30; 31) in coaction with the bogie (7) and the vehicle road wheels (2; 3). |
