Especially for freight, it just doesn't pay off. For passenger, it only seems to help if you want high-speed lines.Eh? All-electric traction means higher tonnage per unit of energy expended, faster climbs up grades, faster acceleration out of depots, you name it. Thermodynamics. If you have high traffic, you will get a return on that infrastructure investment.
