Freight transportation is starting to revert back to the use of trains in at least a partial sense. You will see more and more the back half of an 18-wheeler stacked onto the flat bed of a train. Once the train gets to its destination then the rest of the distance is hauled using an 18-wheeler. This is mainly because trains are about 4 times as efficient freight wise as 18-wheeler freight. With the change in energy costs there will be an even larger shift over the next 5 years. I just wish we would switch over to an electric system like Europe has rather than our diesel system here.
