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.

“An inquiry about the attitude towards the release of so-called political prisoners. I should be very sorry to see the United States holding anyone in confinement on account of any opinion that that person might hold. It is a fundamental tenet of our institutions that people have a right to believe what they want to believe and hold such opinions as they want to hold without having to answer to anyone for their private opinion.”
—Calvin Coolidge (1872–1933)

—James Madison (1751–1836)
