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 are done for—a living dead man—not when you stop loving but stop hating. Hatred preserves: in it, in its chemistry, resides the “mystery” of life. Not for nothing is hatred still the best tonic ever discovered, for which any organism, however feeble, has a tolerance.”
—E.M. Cioran (b. 1911)
