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 dont consider his philosophy long-lived. It is not so much persuasive as full of bravura.”
—Anton Pavlovich Chekhov (18601904)
“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)
“... there isnt a train I wouldnt take,
No matter where its going.”
—Edna St. Vincent Millay (18921950)
