Coupling is done by a worker who must climb between the cars. First he winds the turnbuckle to the loose position, and then he can hang the chain on the hook. After hanging the chain on the towing hook the turnbuckle handle is stowed on the idle hook to prevent damage to itself, the vehicle, or the brake pipes. Only shunting is permitted with a dangling chain. Disconnected brake pipes must be stowed on dummy connectors, to allow proper operation of the brakes. (The picture shows two coupled cars, with a single brake pipe.) The hooks and chain hold the carriages together, while the buffers keep the carriages from banging into each other so that no damage is caused. The buffers can be "dumb" or spring-loaded. That means there are no run-in forces on the coupler.
