Abstract: Cabs, such as passenger and freight cabs, are transferred from one horizontal transport bogie that is moving along a track to another horizontal transport bogie moving at the same speed on an adjacent track. The cab may be transferred from one train or shuttle of moving bogies to another train of moving bogies, or may be transferred from a train of moving bogies to an auxiliary shuttle or bogie on a siding so as to permit the cab to be brought to a stop, either to allow transfer of passengers, to be moved into the car frame of an adjacent elevator for vertical transport within the building, or to simply await the coming of another train, traveling in either the same or in opposite direction, to which the cab may then be transferred.
