"what kind of beer is shipped in train cars? Not any that is likely to be any great loss is my conclusion."
Maybe not in this country, but I heard it from an eyewitness (and a heavy user, I might add) that they used to ship fresh Czech beer to Vienna, Austria by railroad tank car every day. Of course, it is but a short distance there.
After I typed that, a horror went up my spine. What if it was Guinness?
