        "note": "However much power a locomotive has, it can only pull as hard as friction lets the wheels grip: the maximum starting tractive effort = the adhesion coefficient × the weight on the driving wheels. Dry steel-on-steel adhesion is ~0.25 (up to ~0.35–0.4 with sand and modern wheel-slip control), so 200 tons on the drivers gives about 100,000 lbf before the wheels spin. Heavier locomotives and sanders raise the ceiling.",
