Buffers and chain coupler (also called buffers and screw, screw coupler, or English coupler; in EU standards, it's two devices: buffers and draw gear and screw coupling) is the standard train coupling system used in Europe, outside the former Soviet Union. It is also occasionally used outside Europe.

Property Value
dbo:abstract
  • Buffers and chain coupler (also called buffers and screw, screw coupler, or English coupler; in EU standards, it's two devices: buffers and draw gear and screw coupling) is the standard train coupling system used in Europe, outside the former Soviet Union. It is also occasionally used outside Europe. The vehicles are coupled by hand using a hook and links with a turnbuckle that draws the vehicles together. In Britain, this is called a screw coupling. Vehicles have buffers, one at each corner on the ends, which are pulled together and compressed by the coupling device. This arrangement limits the slack in trains and lessens shunting shocks. By contrast, the semi-automatic Janney coupler usually requires comparatively jarring encounters in order to engage the coupling fully. The earliest buffers were fixed extensions of the wagon frames, but later spring buffers were introduced. (en)
