電源

電気式の鉄道車両は、様々な種類の電源から電力を受け取ることができます。

• Wire-Electric - Drawing electrical power from overhead wires , via a pantograph connection
• Battery-Electric - Drawing electrical power from onboard rechargeable batteries
• Diesel-Electric - Generating electrical power 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.
