Well, as monumental as my hiring out was in 1960, it didn't change the way engines were fueled since 1947. They still ran the same mileage and burned the same fuel. Using Rick's formula of 2.5 to 3.0 gallons per mile, that meant a round trip from Lafayette to Louisville and back would still use roughly 1,000 to 1,200 gallons, and since they had 1,200 gallon tanks, they wouldn't have made it if anything unusual had cropped up, so they always fueled them at Louisville.
The freight engines were serviced at the K&IT while the crews laid over (#73's crew came back on #72, and #71's crew came back on #70), and the hostler fueled the passenger engines at the depot at 10th. and Broadway.
There was a little spur track just east of the passenger shed throat, the car knocker would cut the engines off, the herder would line the switches, the hostler would spot the engine(s) on the spur, fuel them, and in summer shut them down. The next morning he would start them early enough for them to warm up, the herder would line him onto the train, the car knocker would make the joint, and the hostler would give the train a brake test. When the crew got on it was ready to go.
In the winter the hostler would fuel them and leave them run, take S/G boiler water at night and again the next morning, and set the S/G's up on standby for the night.
Other than the cost of fuel, the procedure didn't cost the Monon anything extra because the hostler worked a split shift, got paid for four hours in the evening and another four in the morning, and rarely worked over an hour morning and night. It was the best job the Monon ever had. The regular man Clarence Stone (Stony) was a fixture on it, but I always took it whenever there was a vacancy on it. / Ron
PS, if there wasn't an engine change at Lafayette, they fueled there too, both ways. They were very particular about having engines fully fueled. When engines came to the shop, whether it was for routine maintenance or heavy repairs, they were always fueled before they were put in the building.
PS2, I've attached the picture I think you were asking about.
