Sometimes there are two chains, one on each side of the coupler. The chain usually contains a screw-adjustable link to allow close coupling. These variants are also used elsewhere. On sharp curves, a single centre buffer is less likely to be subject to buffer-locking. The Eritrean Railway also uses a centre buffer and chain coupler.
A link-and-pin coupler Transition era AAR knuckle coupler. The gap in the knuckle accommodates the link of a link and pin coupler and the vertical hole in the knuckle accommodates the pin. Link and pin coupler combined with side buffers on a Panama canal mule. The link-and-pin coupling was the original style of coupling used on North American ...
In many heavy-haul applications, such as for coal and iron ore, either US AAR-type couplers or Soviet SA-3 couplers are used. Conversion is made harder to justify because the existing buffer and chain coupling is almost universal. Meanwhile, drawgear of new rolling stock is being built at a height suitable for conversion.
A pneumatic buffer with sections cut away. A buffer is a part of the buffers and chain coupler system used on the railway systems of many countries, among them most of those in Europe, for attaching railway vehicles together (in North America, rolling stock instead has draft gear built into the couplers).
SA3 couplers Click here for animation of coupling SA3 details End view of SA3 coupler, with release lever to the left.. SA3 couplers (also known as СА3 or СА-3 couplers per the typical foundry stamp on top of these couplers, meaning "Советская Автосцепка, 3" in Russian or "Soviet Auto-latch 3" in English) or Willison coupler and Russian coupler are railway couplings used ...
[2] [3] Some Russian locomotives and wagons have buffers together with the central coupler. When coupling to Finnish equipment, a short chain with a block that fits in the central coupler is placed on the Russian side, backing up and compressing the buffers so that the chain can be laid on the hook. (That is also the common way of coupling ...
The 777X is back in flight test, and we have a good handle on fixing the thrust link issue we uncovered. Now, moving to the third area, culture change. ... our buffer inventory has grown to ...
This chain link has side lengths of different lengths, so the length of the coupling chain for separating or tensioning the train can be varied by simply turning the chain link. With the introduction of transporter wagons , the balancing lever coupling was combined with the funnel coupling on most of the narrow-gauge railways in order to be ...
