OGR Webmaster posted:In steam's "modern era" (1930s to the end of steam in the 50s) steam locomotive tenders were sized so they could typically run 100 miles on one tender of water with an appropriate reserve.
An example...the 765's tender holds 22,000 gallons. Over her excursion career she has averaged about 120 gallons per mile. 22,000/120 = 183 miles.
She likely worked harder in regular freight service, so her water consumption would be higher.
150 gallons per mile = 146 miles
160 gallons per mile = 137 miles.
100 miles per division and water stop works out just right.
I remember reading in some older books about how engineer would have to unhook the engine and "run for water" because the try cocks or water glass were getting low/empty and didn't want the crown sheet exposed (exposed sheet kinda ruins the boiler, engineer, conductor, brakeman as well as machinery, and maybe things up to half mile away.)
