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'.

Famous quotes containing the word train:

    We see us as we truly behave:
    From every corner comes a distinctive offering.
    The train comes bearing joy....

    Children must eventually train their own children, and any impoverishment of their impulse life, for the sake of avoiding friction, must be considered a possible liability affecting more than one lifetime
    Erik H. Erikson (20th century)

    Still, I am prepared for this voyage, and for anything else you may care to mention.
    Not that I am not afraid, but there is very little time left.
    You have probably made travel arrangements, and know the feeling.
    Suddenly, one morning, the little train arrives in the station, but oh, so big
    It is! Much bigger and faster than anyone told you.
    John Ashbery (b. 1927)
