A truck-train system uses a first (“A”) railway dolly or bogie to support the front or fifth-wheel hitch end of roadable truck-trailer. It uses a second (“B”) railway dolly to support the rear or roadable wheel end of the same truck-trailer. The first (“A”) and second (“B”) railway dollies are connected to each other by a longitudinal support member having a telescoping central sill. The central sill is adapted to be detachably connected to the first (“A”) railway dolly. The longitudinal support member is connected to the second (“B”) railway dolly and also supports a raised platform having a deployable ramp for receiving the wheels of a roadable truck-trailer. The telescoping central sill and longitudinal support member can be locked in any fixed position to take up the train draw-bar tension and to provide for truck-trailers of various lengths.
