RichiH, 23 days ago The #train from Toronto to the airport not only has a diesel engine, it also has a gearbox and shifts gears. A train! Not constant speed with generator and electric motors for higher efficiency, lower weight, lower cost, and less complexity. Don't think I ever was in one of those -- or if I was, I certainly didn't hear and feel the engine.
