Eight-axle, Saadkms type “piggyback” flat rail-wagons are used by various railway companies, e.g. Hupac (Switzerland) and ÖBB (Austria) for transalpine transport of heavy goods vehicles. In special terminals, trucks drive directly from the street onto the wagon via a ramp to be transported to their destination. The drivers can rest in a special sleeping car, reboard their trucks at their destination and deliver the goods safely to their customers.
This form of combined road-rail transport – Rolling Highway – is rapidly gaining importance, not least due to a significant increase in the volume of traffic and a growing environmental awareness. According to recent statistics, Rolling Highway transport accounted for approx. 29% of all international shipments in 2002 (data provided by the International Union of Combined Road Rail Transport Companies – UIRR, May 2003).
Apart from economic advantages such as reduced infrastructure costs, this form of transport also offers advantages to customers, for example:
