Hello everyone, I have a couple of questions about screw-link/buffer and chain couplings, commonly found on British and other European rolling stock.
1. By the nature of the coupling, each vehicle has a chain, often with an adjustable screw to tighten the coupling. So when two vehicles are coupled together, does it matter which vehicle's chain is used, or does it not matter which chain the shunter uses to connect them?
2. Different rolling stock had different kinds of buffers. Some had oval-shaped buffers, some had square or rectangular buffers, and some had circular buffers. How was the kind of buffer that would be used on the vehicle determined?
3. Early DMUs and some EMUs had standard screw-link couplers, but they changed to other designs later on. Could one of these early DMUs or EMUs theoretically pull non-multiple-unit stock, like a goods van or a standard passenger coach?
