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:

“I would love to meet a philosopher like Nietzsche on a train or boat and to talk with him all night. Incidentally, I don’t consider his philosophy long-lived. It is not so much persuasive as full of bravura.”
—Anton Pavlovich Chekhov (1860–1904)

“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)

“The logical English train a scholar as they train an engineer. Oxford is Greek factory, as Wilton mills weave carpet, and Sheffield grinds steel. They know the use of a tutor, as they know the use of a horse; and they draw the greatest amount of benefit from both. The reading men are kept by hard walking, hard riding, and measured eating and drinking, at the top of their condition, and two days before the examination, do not work but lounge, ride, or run, to be fresh on the college doomsday.”
—Ralph Waldo Emerson (1803–1882)
