No water towers or coaling stations. Getting good water to avoid scaling is an art. My Grandfather was a water tester for the CB&Q prior to WW I he passed the pharmacy exam at 19 but had to wait two years to get his license. He served in WW I as a Captain in the 123rd Field artillery a converted infantry unit. He was on the throttle on the first train into Casper Wyoming that is how highly the crews rated him. He kept his license active until just before he died at age 63. He worked for Bowser pumps out of England setting out gas stations and Military fueling system all over the US during WW II. The US branch of the Company went out of business after he was fired for making 4 times as much on Commision as the company president was on salary. Eidetic memory once seen never forgotten was his gift and curse. He never could forget what he saw during WW I. Never forgot a how to make anything in the Pharmacy or where a bottle had been put away. He helped a Local Pharmacy when he was in town.
