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:
“We laugh at him who steps out of his room at the very moment when the sun steps out, and says: “I will the sun to rise”; and at him who cannot stop the wheel, and says: “I will it to roll”; and at him who is taken down in a wrestling match, and says: “I lie here, but I will that I lie here!” And yet, all laughter aside, do we ever do anything other than one of these three things when we use the expression, “I will”?”
—Friedrich Nietzsche (1844–1900)
