  1. I've been told that you can't be sloppy with steam by an elderly friend of mine who started out as an apprentice mechanic in the railways. He told me about a particular articulated locomotive type (Beyer-Garratt) which required a fine touch in maintenance. One of these went out of the shop one day after major overhaul, and a few days later it was back - the crews said it "ran like a dog, and even that's insulting to dogs". The mechanics went over it with a fine-tooth comb and found something (can't remember what, but it was some form of duct/pipe associated with the stack) was out of alignment by 1/4". They re-aligned whatever it was and that fixed the problem. Amazing that the equivalent of about 6mm of misalignment could cause a noticeable degradation in performance.
