Power
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:
“‘Tis not such lines as almost crack the stage
When Bajazet begins to rage;
Nor a tall met’phor in the bombast way,
Nor the dry chips of short-lunged Seneca.
Nor upon all things to obtrude
And force some odd similitude.
What is it then, which like the power divine
We only can by negatives define?”
—Abraham Cowley (1618–1667)
“Nature’s law says that the strong must prevent the weak from living, but only in a newspaper article or textbook can this be packaged into a comprehensible thought. In the soup of everyday life, in the mixture of minutia from which human relations are woven, it is not a law. It is a logical incongruity when both strong and weak fall victim to their mutual relations, unconsciously subservient to some unknown guiding power that stands outside of life, irrelevant to man.”
—Anton Pavlovich Chekhov (1860–1904)
“I, who cannot stay in my chamber for a single day without acquiring some rust,... confess that I am astonished at the power of endurance, to say nothing of the moral insensibility, of my neighbors who confine themselves to shops and offices the whole day for weeks and months, aye, and years almost together. I know not what manner of stuff they are of,—sitting there now at three o’clock in the afternoon, as if it were three o’clock in the morning.”
—Henry David Thoreau (1817–1862)
