A vehicle, particularly a semitrailer (20), is adapted for driving on both a road and a railroad track. The semitrailer comprises a traction vehicle (20a), which is joined articulately to a trailer (20b). The traction vehicle (20a) has a front rail-wheel unit (5) and a rear rail-wheel unit (7), whereas the trailer (20b) includes only one rear rail-wheel unit (22). At least one of the two latter rail-wheel units (7, 22) includes drive means, and one or both of said units may consist of a bogie that includes two axles, or one or both of said units may be a single-axle unit. All rail-wheel units are vertically movable to enable the vehicle to be placed on the railroad and adjacent rubber wheels to be lifted.

L'invention concerne un véhicule, en particulier un semi-remorque (20) conçu pour rouler à la fois sur la route et sur des rails de chemin de fer. Le semi-remorque comprend un véhicule de traction (20a) relié à une remorque (20b) au moyen d'une attache articulée. Le véhicule de traction (20a) est équipé d'une unité avant de roulage sur rails (5) et d'une unité arrière de roulage sur rails (7), alors que la remorque (20b) n'est équipé que d'une seule unité arrière de roulage sur rails (22). Au moins une des deux dernières unités de roulage sur rails (7, 22) comporte des moyens d'entraînement, et une de ces unités peut être constituée d'un bogie à deux axes, ou bien l'une de ces unités ou les deux ne comprennent qu'un seul axe. Toutes les unités de roulage sur rails sont mobiles verticalement afin de permettre le placement du véhicule sur les rails de chemin de fer et le relevage des roues équipées de pneumatiques.
