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:

    Perfect present has no existence in our consciousness. As I said years ago in Erewhon, it lives but upon the sufferance of past and future. We are like men standing on a narrow footbridge over a railway. We can watch the future hurrying like an express train towards us, and then hurrying into the past, but in the narrow strip of present we cannot see it. Strange that that which is the most essential to our consciousness should be exactly that of which we are least definitely conscious.
    Samuel Butler (1835–1902)

    ... there isn’t a train I wouldn’t take,
    No matter where it’s going.
    Edna St. Vincent Millay (1892–1950)

    Put me on a moving train if I’m sick, and I’ll get well. It’s good for mind and body to get out and see the world.
    Maria D. Brown (1827–1927)
