ABSTRACT:
A railroad car has supported on its frame a trailer-handling rack construction including a pair of runners adapted to receive the tandem or highway wheels of a semitrailer. The runners are turnable laterally and shiftable longitudinally of the car. A trailer is loaded onto the car from a platform at the side of the car by action only of a highway tractor or railroad yard tractor. As the trailer is backed onto the car, the highway wheels of the trailer reverse roll onto the pair of runners and to a position approximately at the transverse center of the car, the highway wheels are then restrained to the runners. Backing the trailer is continued while tractor-maneuvering the trailer forward portion to the transverse center of the car. Simultaneously, the trailer rearward portion is conveyed on the pair of runners, the runners turning laterally and shifting longitudinally of the car. In loading the trailer on the car, the forward and rearward portions of the trailer are conveyed oppositely laterally in skewing movements and the trailer moved to a piggyback disposition on the car.
