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:
“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)
“Constant revolutionizing of production ... distinguish the bourgeois epoch from all earlier ones. All fixed, fast-frozen relations, with their train of ancient and venerable prejudices are swept away, all new-formed ones become antiquated before they can ossify. All that is solid melts into air, all that is holy is profaned, and man is at last compelled to face with sober senses, his real conditions of life, and his relations with his kind.”
—Karl Marx (1818–1883)
“Misfortunes leave wounds which bleed drop by drop even in sleep; thus little by little they train man by force and dispose him to wisdom in spite of himself. Man must learn to think of himself as a limited and dependent being; and only suffering teaches him this.”
—Simone Weil (1909–1943)
