Rail Support (sleeper/tie)
Main article: Railroad tieA railroad tie (also called a cross-tie in North American usage, or a railway sleeper outside North America) is a rectangular object on which the rails are supported and fixed. The tie has two main roles: to transfer the loads from the rails to the track ballast and the ground underneath, and to hold the rails to the correct width apart (to maintain the rail gauge). They are generally laid transverse (perpendicular) to the rails.

Famous quotes containing the words rail and/or support:
“Old man, it’s 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 (1928–1974)
“They [parents] can help the children work out schedules for homework, play, and television that minimize the conflicts involved in what to do first. They can offer moral support and encouragement to persist, to try again, to struggle for understanding and mastery. And they can share a child’s pleasure in mastery and accomplishment. But they must not do the job for the children.”
—Dorothy H. Cohen (20th century)
