ABSTRACT:
A special wagon has at one end thereof a movable ramp which may be lowered simultaneously with buffers on the wagon. The movable ramp and a platform of the wagon carry rails on which the bogies can roll. Arranged in parallel with these rails are C-shaped slideways, in which are displaced chains, ends of which carry hooks for holding a bogie and for pulling it up the ramp and onto the platform. The chains and hydraulic jacks for maneuvering the ramp receive working fluid from a motor-driven pump unit via controls. The platform of the wagon carries systems for securing bogies for rail travel.
