Abstract
Individual road transport and rail-bound transport are combined with rapid transfer from one transport mode to the other. The transport units for individual traffic are semi-trailer trucks. The load and transported-material bearing semi-trailer are transferred by cross-rolling onto the low-platform railroad car for rail-bound shipping. The tractor-truck serves only as a power plant and supports docking. Thereafter the tractor is again available for other transports in individual traffic. The energy of motion is supplied from the tractor-truck through extensible power or air lines to the semi-trailer and these lines are disconnected following docking. Locks are provided to secure the position of the semi-trailer on the low-platform railroad car and these locks are of the self-service type. Means for anti-tipping are provided at the apron and/or at the low-platform railroad cars to prevent their tipping during load transfer. These means for anti-tipping consist of latches movable along the low-platform railroad cars which engage matching shaped-sections at the apron.
