Train

A train is a connected series of rail vehicles propelled along a track (or "permanent way") to transport cargo or passengers.

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 limited monorails and maglev guideways in the mix.

The word 'train' comes from the Old French trahiner, from the Latin trahere 'pull, draw'.
