The Joke is for all of you who don't know trains, is that locomotives have been using hybrid technology from pretty much day. A "diesel" locomotive has a diesel engine turning a generator just like a hybrid car has a engine turning a generator. Also locomotives have had regenerate brakes for years they are called dynamic brakes. The fact that people call this technology new is a joke because the railroads have been using the technology for years.
