Electric Powersource

There are a few types of electric powertrains , depending on where they get electricity from:

• Wire-Electric - Drawing electricity from overhead wires , with a pantograph connection.
• Battery-Electric - Drawing electricity from onboard rechargeable batteries.
• Diesel-Electric - Generating electricity onboard, with an internal combustion engine .

While their visual and auditory presence may be vastly different from one another, all these types of vehicles use similar drivetrains for propulsion - traction motors , powered by electricity.
