Abstract:

A conversion apparatus (10) for converting a vehicle (V) for travel on a railway comprises first and second assemblies (20, 20') connected by an axle (23). Each assembly (20, 20') comprises a first support member (11) rigidly mounted to the vehicle frame and a second support member (13) pivotally mounted to the vehicle frame. The second support member is coupled to the first support member for limiting the pivotal movement of the second support member relative to the vehicle frame. A pair of railway wheel support arms (18, 18') are pivotally mounted to the second support member (13) for movement between raised and lowered positions and carry a railway wheel (21) rotatably mounted thereon. A hydraulic cylinder (22) moves the railway wheel support arms between the raised and lowered positions. An extendable and retractable tongue (37) is provided for coupling and decoupling the assembly to the vehicle suspension while providing a slidable supporting engagement with the vehicle suspension when the tongue is coupled to the vehicle suspension.
