A diesel-electric hybrid is a vehicle that is powered by both a diesel engine and an electric motor. Trains have relied on this technology for decades. Hybrid vehicles have become popular for their ability to provide zero emissions when running on electricity and improved fuel economy on the road. Diesels are also popular, especially for public
