Abstract: A bogie for use in an intermodal transport system has wheels rotatably mounted about two spaced parallel axes, and a coupling device (33) for securing the bogie to a wheeled rail wagon, one end of which is supported on the bogie. The coupling device (33) cooperates with a coupling device, provided at that end of the wagon, which are adapted to couple the wagon to another wagon or to a locomotive in normal use of the wagon.An intermodal transport system comprises such a wagon; a drive device, e.g. a tractor for road and a locomotive for rail; and a bogie provided with road wheels or rail wheels of a gauge different to that of that of the wagon, in accordance with the mode of transport over which the wheeled wagon is to be transported.
