A rail-road intermodal freight system. In an embodiment, a plurality of L-cars are provided. In an embodiment, each L-car may be configured for support at its forward end on a preceding L-car, and at a rear base on a set of flanged rail wheels. In implementing the system, a freight yard is provided with rail components which are switchable to enable decoupling and a turn-in-place operation, wherein each care is lifted from the preceding L-car in the train, and the neck portion of the L-car lowered to the ground. When in the lowered position, downwardly extending legs on the over-the-road trailer enable an over-the-road tractor to attach the over-the-road trailer in conventional fashion, for removal of the over-the-road tailer from the L-car. Loading of an over-the-road trailer on the L-car takes place via a reverse process, wherein the trailer is backed up on to the L-car.
