If you every stood beside a freight train when they first start moving, you'd hear all the slack being taken up at each coupling with an echo of clunks all the way to the last car.Very cool video.
I guess I never paid attention, but I never realized the real ones allow as much slack as they do.
Now you know why we still have buffers on smaller freight cars.Cool video, thanx!
I often wonder why some countries still use links or chains, guess it’s a budget thing.
