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:
“Our national determination to keep free of foreign wars and foreign entanglements cannot prevent us from feeling deep concern when ideals and principles that we have cherished are challenged.”
—Franklin D. Roosevelt (18821945)
“Old man, its four flights up and for what?
Your room is hardly any bigger than your bed.
Puffing as you climb, you are a brown woodcut
stooped over the thin rail and the wornout tread.”
—Anne Sexton (19281974)
“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 (18081855)
