    "data": {
        "note": "Grade resistance is the dominant force on a hill: about 20 lb per ton per 1 % of grade (it is just the weight component along the slope), so a 5,000-ton train on a 1 % grade fights 100,000 lbf before it even rolls. Curve resistance adds roughly 0.8 lb per ton per degree of curve from wheel-flange friction. This excludes the speed-dependent rolling/air resistance (the Davis equation), which dominates on the flat at speed.",
