A buffer stop or bumper (US) is a device to prevent railway vehicles from going past the end of a physical section of track.
The design of the buffer stop is dependent in part upon the kind of couplings that the railway uses, since the coupling gear is the first part of the vehicle that the buffer stop touches. The term "buffer stop" is itself of British origin, railways in Great Britain principally using buffer-and-screw couplings between vehicles.
Famous quotes containing the word stop:
“You don’t hit a child when you want him to stop hitting. You don’t yell at a children to get them to stop yelling. Or spit at a child to indicate that he should not spit. Of course, you want children to know how to sympathize with others and to “know how it feels,” but you ... have to show them how to act—not how not to act.”
—Jeannette W. Galambos (20th century)
