I didn't realize it was possible for one stoker to keep a boat going. I remember the display of the DM&IR Yellowstone locomotive in Duluth mentions that it was not possible to handfire a Yellowstone because at track speed (circa 20 MPH) pulling 18,000 tons of ore cars + the weight of the locomotive, it needed 350 pounds of coal PER MINUTE to keep up steam.
I'm pretty certain the gross tonnage of the Morrow loaded was quite a bit less than 18,000 tons. But the rolling resistance of a steel wheels on rail is also a lot less than a hull through the water. Curious if anyone knows how many pounds of coal per hour or per minute that stoker had to throw into the Morrow's firebox to maintain speed.
By comparison I don't think I'll ever complain again about what it takes to keep my wood boiler going in the depths of a Minnesota winter. :) :)

The Independent had two firemen on a watch to shovel coal while the smaller Morrow only had one per watch. After many hours of racing side by side the Independent broke the 9 mph barrier and inched ahead of the Morrow. On my 4-8 watch on the Independent the bigger fireman always had 6 eggs and pancakes for breakfast after our watch. The smaller fireman only had 4 eggs and pancakes.
