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:

    The landscape of the northern Sprawl woke confused memories of childhood for Case, dead grass tufting the cracks in a canted slab of freeway concrete. The train began to decelerate ten kilometers from the airport. Case watched the sun rise on the landscape of childhood, on broken slag and the rusting shells of refineries.
    William Gibson (b. 1948)

    We teach boys to be such men as we are. We do not teach them to aspire to be all they can. We do not give them a training as if we believed in their noble nature. We scarce educate their bodies. We do not train the eye and the hand. We exercise their understandings to the apprehension and comparison of some facts, to a skill in numbers, in words; we aim to make accountants, attorneys, engineers; but not to make able, earnest, great- hearted men.
    Ralph Waldo Emerson (1803–1882)

    An immoderate fondness for dress, for pleasure, and for sway, are the passions of savages; the passions that occupy those uncivilized beings who have not yet extended the dominion of the mind, or even learned to think with the energy necessary to concatenate that abstract train of thought which produces principles.... that women from their education and the present state of civilized life, are in the same condition, cannot ... be controverted.
    Mary Wollstonecraft (1759–1797)
