An articulated spine car (10) comprising a plurality of units (12a-d) joined by connectors (14). The preferred car comprises a pair of end units (12a, d) and at least two intermediate units (12b,c). Each of the units (12a-d) preferably comprises a central longitudinal spine (16), a wheel support platform (18) for supporting the wheels of a semitrailer, and a hitch (20) for attachment to a semitrailer kingpin. The wheel support platforms (18) are preferably disposed at relatively low elevations on each side of the spine (16), and the spine (16) preferably includes a lowered portion between the wheel support platforms (18) to accommodate semitrailer axles. |
