In United States railroading, the term national rail network refers to the entire network of interconnected standard gauge rail lines in North America. It does not include most subway or light rail lines. Federal Railroad Administration regulations require passenger cars used on the national rail network to be heavy and strong enough to protect riders in case of collision with freight trains. Most mass transit vehicles do not meet this requirement. Commuter rail equipment generally does, as do all Amtrak cars. Mass transit systems that do not meet FRA requirements cannot even be connected to the national rail network, unless the connection layout only permits the transfer of one or two cars at a time, for example via a Y stub siding.
Famous quotes containing the words national, rail and/or network:
“While I do not think it was so intended I have always been of the opinion that this turned out to be much the best for me. I had no national experience. What I have ever been able to do has been the result of first learning how to do it. I am not gifted with intuition. I need not only hard work but experience to be ready to solve problems. The Presidents who have gone to Washington without first having held some national office have been at great disadvantage.”
—Calvin Coolidge (1872–1933)
“We rail at trade, but the historian of the world will see that it was the principle of liberty; that it settled America, and destroyed feudalism, and made peace and keeps peace; that it will abolish slavery.”
—Ralph Waldo Emerson (1803–1882)
“How have I been able to live so long outside Nature without identifying myself with it? Everything lives, moves, everything corresponds; the magnetic rays, emanating either from myself or from others, cross the limitless chain of created things unimpeded; it is a transparent network that covers the world, and its slender threads communicate themselves by degrees to the planets and stars. Captive now upon earth, I commune with the chorus of the stars who share in my joys and sorrows.”
—Gérard De Nerval (1808–1855)
