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:
“Men who want to support women in our struggle for freedom and justice should understand that it is not terrifically important to us that they learn to cry; it is important to us that they stop the crimes of violence against us.”
—Andrea Dworkin (b. 1946)
