The future of freight travel looks to incorporate vehicles capable of moving on roads and on rails. These massive modern vehicles combine the capabilities of road trucks with freight trains and the result is the rail-road truck.
The proposed truck will have two separate sets of wheels, one for the road and the other for the rail. Although existing only in theory, a vehicle like this has the ability to alter the transportation industry as we know it. Currently, many products that cross large countries require various transfers between freight trains, travel liners and airplanes. With hybrid freight and travel liners, one travel element is completely eliminated.
Designers are also concerned with how these large vehicles can better take advantage of space. For example, traffic on highways will be much improved if most transport vehicles travel on railways rather than roads.
