When a complete truck – tractor unit, driver, and load – travels by rail over a long-distance segment, the service is called a rolling highway (RoLa). The driver steers the vehicle onto low-floor rail wagons at a loading ramp, rides in a passenger car attached to the train, and resumes driving at the destination terminal. As a form of accompanied intermodal transport, the rolling highway is primarily deployed where road access is politically or geographically constrained, most notably on transalpine corridors. Carriers benefit from reduced fuel consumption and driver fatigue on the rail leg; governments use the service as a modal-shift instrument to relieve road infrastructure. Unlike unaccompanied piggyback services – where trailers or swap bodies travel without the tractor unit – the rolling highway requires the full vehicle combination to be loaded.
