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:
“What the vast majority of American children needs is to stop being pampered, stop being indulged, stop being chauffeured, stop being catered to. In the final analysis it is not what you do for your children but what you have taught them to do for themselves that will make them successful human beings.”
—Ann Landers (b. 1918)
