United States of America
Usually, North American locomotives have sand that can be dumped out either in front of or behind the trucks of a locomotive. In modern diesel locomotives there is a button that the driver will press to start sand dump. This button is tied to a computer system that determines the train's direction and where the sand should be applied: either forward or aft of the trucks. In older locomotives, though, there was a manual lever attached to a valve that had three positions: Off, Forward, and Aft. The engineer could flip this lever to dump sand in correspondence with the train's movement.

Famous quotes containing the words united states, united, states and/or america:
“I have ever deemed it fundamental for the United States never to take active part in the quarrels of Europe. Their political interests are entirely distinct from ours. Their mutual jealousies, their balance of power, their complicated alliances, their forms and principles of government, are all foreign to us. They are nations of eternal war.”
—Thomas Jefferson (1743–1826)
“So here they are, the dog-faced soldiers, the regulars, the fifty-cents-a-day professionals riding the outposts of the nation, from Fort Reno to Fort Apache, from Sheridan to Stark. They were all the same. Men in dirty-shirt blue and only a cold page in the history books to mark their passing. But wherever they rode and whatever they fought for, that place became the United States.”
—Frank S. Nugent (1908–1965)
“The Constitution of the United States is not a mere lawyers’ document. It is a vehicle of life, and its spirit is always the spirit of the age. Its prescriptions are clear and we know what they are ... but life is always your last and most authoritative critic.”
—Woodrow Wilson (1856–1924)
“Two things in America are astonishing: the changeableness of most human behavior and the strange stability of certain principles. Men are constantly on the move, but the spirit of humanity seems almost unmoved.”
—Alexis de Tocqueville (1805–1859)
