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 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 (18031882)
“In order to really enjoy a dog, one doesnt merely try to train him to be semihuman. The point of it is to open oneself to the possibility of becoming partly a dog.”
—Edward Hoagland (b. 1932)
“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)
