Hello-
In regaurds to track elevation, I live next to the B&A. (Boston and Albany) on CSX's Berkshire Subdivision. Through the villiage I live in the track graidiant is between .04-.70 in a 6 mile distant. Trains are always pulling hard Eastbound and Westbounds are in Dynamics the whole way. The roulling grade on the line is at in a town called Washington, and there the tracks on the east side is 1.2% for a few miles, the west side of the grade is much steeper. 1.8%, this dont seem like a lot but train tonnage is not to exeed 9000 tons, due to the sharp curves and steep grades.
