From its inception, the subway used trolleys powered by electricity from overhead lines, made possible by the invention of the trolley pole in 1880 by Frank J. Sprague. However, the modern line has been pantograph-only since the trolley wires were modified in the 1990s.

Famous quotes containing the word power:
“I am firmly opposed to the government entering into any business the major purpose of which is competition with our citizens ... for the Federal Government deliberately to go out to build up and expand ... a power and manufacturing business is to break down the initiative and enterprise of the American people; it is the destruction of equality of opportunity amongst our people, it is the negation of the ideals upon which our civilization has been based.”
—Herbert Hoover (1874–1964)
“The continuance of our passions is no more in our own power than the term of our life.”
—François, Duc De La Rochefoucauld (1613–1680)
“I never saw love as luck, as that gift from the gods which put everything else in place, and allowed you to succeed. No, I saw love as reward. One could find it only after one’s virtue, or one’s courage, or self-sacrifice, or generosity, or loss, has succeeded in stirring the power of creation.”
—Norman Mailer (b. 1923)
