First a bit of train history. Trains carry a lot of heavy and bulky goods for long distances. Now almost all trains use diesel engines for propulsion. But in the past most trains were electric and driven by overhead wires, the train used no fuel. The electricity could be from any source including hydropower. I

To properly regulate the charging, the alternator should have a regulator instead of the resistor. The regulator will shut off the charging when the battery
