0-6-0 and Grades
An 0-6-0 Switcher with a sloped tender, and the point is that long engines do not take tight curves with the grace of a smaller engine. The same with carriages. As well an incline with a curve is harder still for a train to manage which means the winding road that goes up hill might lead to tears for the masters of giant steam trains.
An 8 inch rise at 4% requires around 144 inches of track and another 144 inches of track to get all the way back down again. That's something like 8 yards of railway line. So it's all very exciting to think of 8 inches as something like 100 feet. At the same time adding up and subtracting, the multiplication tables, division are none of them strong points in your correspondent.
