Abstract: The railway/road transportation system according to the present invention consists of at least one combined railway/road transport railway station comprised of at least a railway track (60) and at least one track platform (61 or 62) for loading and unloading wagons (1) arranged for skew loading/unloading. The invention is characterized in that each wagon (1) consists of two end platforms (2) and (3) and a railway structure (6) bearing a road car load mounted pivoting on said wagon (1) and linked to the end platforms (2) and (3) by detachable and locking links rigidly assembled. Each station (63) is equipped on the ground with at least means for lifting, lowering and swiveling the carrier structure (6) enabling to detach and pivot towards the track platform (61) or (62) equipped with means for picking up and receiving (64) or (65) the assembly comprising means for maintaining in position and for presenting the end platforms (2) and (3). Each wagon (1) is provided with a center (28) of rotation for the road load bearing railway structure (6) and detachable strong and locking connections of a rigid assembly, which connect the bearing railway structure (6) in a body with the end platforms (2 and 3). Each station (63) for loading/unloading is provided on one side with at least one additional device for centering the platform (2, 3) or one or several wagons (1). The method of loading/unloading a rake of wagons through the mediation of the above-described system is characterized in that the rake of wagons is immobilized by placing each wagon (1) underneath a loading/unloading station (63), subsequently at least one wagon is centered by a relevant device to the equipment located on the ground. Then, immobilization of the end platforms (2 and 3) takes place at their initial positions in that station (63), the detachable connections of the rake of wagons are unlocked and means for lifting, lowering and swiveling the carrier structure (6) is brought into motion, which results in lifting at least one end of the carrier structure (6) above the level needful for turning. Subsequently the carrier structure (6) turns until its taking over by corresponding means placed on the platform (61, 62) or platforms (61 and/or 62) and line the railway track, whereby the turning stop only when the angular deviation of the carrier railway structure (6) is sufficient for direct access the road load from the platform, when the road vehicle enters or leaves the carrier railway structure (6), whereupon turning operation starts and lasts until the carrier railway structure (6) assumes the position in the direction for connection. Subsequently, lowering of the entire carrier railway structure (6) takes place until the end arms thereof are exactly at the entry of the receiving means to secure sufficient support of the carrier railway structure (6) by a mechanical joint. Then, lowering of said carrier railway structure (6) takes place such as the ends of the arms retract into the receiving portion, the fixed detachable connections lock, the means of lifting and lowering is removed, the end platforms (2, 3) release from their positions and device for centering is removed.
