Abstract: Prior battery-powered electric locomotives have used multiple diesel engines to charge the batteries and have not been commercially accepted. The present invention provides a yard switcher which combines battery storage with a gas microturbine generator to provide an effective fuel-efficient and environmentally friendly locomotive.
