Fellows, I wasn't going to get involved you your scaling discussions as I don't feel up to your capacities. But why scale water? If the scale is 22.5 to 1 and a little locomotive will run 20 minutes on one watering and fueling, which is 1/3 of and hour, that times 22.5 is 7.5 hours of running without stopping. Was there ever a steam locomotive that was supposed to run 7.5 hours without stopping for some reason or another and the engineer did not say "filler up"?
