Hi Louis, I would think in STEAM days there were many helper grades on the Q. The helpers may have been used only occasionally for extra heavy trains. I would think a eastbound heavy train out of Savanna would have been helped to Burke. Same would hold for both directions out of Ottumwa. These probably were not daily occurrences, but as needed. I know on the Milwaukee Road grades as flat as 0.6% in certain cases, required helpers for heavy trains to keep a line fluid and not have trains reducing tonnage, or doubling hills. People with more Q knowledge please add to the list. ted At 03:51 PM 8/24/2017, you wrote: August 24, 2017 Ted Schnepf railsunl@sbcglobal.net 847-697-5353 126 Will Scarlet Elgin, Ill. 60120 http://RailsUnlimited.ribbonrail.com/ Model Railroad Sales and Service with a personal touch.
