Trains and bits

''The Information Train is a scientific experiment that I presented at the Wizards of Science 2009 contest over the past weekend. The entry demonstrates how computers communicate with each other by setting up a network in which a model train transfers a picture's pixels from one computer to the other.'' [source, with video]

However this is hardly new stuff. There was an article in Scientific American in the 80s describing a "Turing train" that could do the same.
And a German project built that train some years ago [source]

At this site they discuss how to do arithmetic with Turing trains.
