Glossary Results for Word "Coupling"
|Coupling||Part of the draw gear, device for connecting one vehicle to the next. Couplings on goods wagons were simply three links of stout chain (vehicles so connected were termed “loose coupled”.) See also Instanter couplings.
Couplings on passenger rated stock were slightly more sophisticated, with the central link being replaced by a screw thread which enabled the coupling to be adjusted so as to keep the adjacent buffers in contact and under compression so as to avoid surging and oscillation.
