I was a bit disappointed in this program. It does a good job explaining intermodal operations in general, but I think most model railroaders and railfans understand this already.... The segment on roadrailers was interesting, and a roadrailer train being put together is not something that is seen often. But, I would have liked to have seen more scenes of intermodal trains in operation out on the rails. Not that this was a total disappointment, others may find this DVD very good.
