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:
“Speak, nameless, power and might;
when will you leave me quite?
when will you break my wings
or leave them utterly free
to scale heaven endlessly?”
—Hilda Doolittle (1886–1961)
“How oft when men are at the point of death
Have they been merry! which their keepers call
A lightning before death: O, how may I
Call this a lightning? O my love! my wife!
Death, that hath sucked the honey of thy breath,
Hath had no power yet upon thy beauty:
Thou art not conquered; beauty’s ensign yet
Is crimson in thy lips and in thy cheeks,
And death’s pale flag is not advanced there.”
—William Shakespeare (1564–1616)
“You only have power over people so long as you don’t take everything away from them. But when you’ve robbed a man of everything he’s no longer in your power—he’s free again.”
—Alexander Solzhenitsyn (b. 1918)
