Locomotion

American railroads, how they sparked big business and changed the economy of the United States forever. The weakest of the shows, still very good.

The railroad's infancy in Great Britain during the 19th century. This was the highlight for me. Very well done, insightful, and surprisingly surreal in some moments.

The train's role in both World Wars. Learned lots of things. Again, a great, informative show, with some outstanding camera-work. Especially impressive were some present-day shots of refurbished battle trains plowing through the fog.

This one covers several topics, but focuses on how the railroad has affected the world in general. Hosted by the ubiquitous Jack Perkins (who narrates all the episodes, but only physically hosts here), this episode teaches us about both the past and the present, including a look at Japan's railway innovations. Slightly different format; doesn't ruin the show though.
