Translations:Coupling/1/en

Coupling is the method of connecting rail vehicles together and forming a train. The coupling system in Derail Valley is universally known as “chains and buffers”. Vehicles are kept together by a tightly screwed chain, but held at a distance by shock absorbers known as buffers. Apart from the chain and buffers, there are air hoses between the vehicles. When connected and with their valves open, they form a shared pressurized air vessel throughout the train, as part of the train brake system.
