Chris heads to the Arctic to explore a railway which probably should never have been built, the Alaska Railroad. Constructed when the USA's largest state was barely populated, Chris wants to find out why it has become such a success. But travelling at the tail end of winter with few trains, completing his journey to the end of the line in Alaska's frozen interior is not going to be easy.
