The train
Motive power is provided by a separate locomotive or individual motors in self-propelled multiple units. Although historically steam propulsion dominated, the most common modern forms are diesel and electric locomotives, the latter supplied by overhead wires or additional rails. Other energy sources include horses, rope or wire, gravity, pneumatics, batteries, and gas turbines.
Train tracks usually consists of two, three or four rails, with a limited number of monorails and maglevguideways in the mix.
The word 'train' comes from the Old Frenchtrahiner, from the Latintrahere 'pull, draw'.
