Hi, A question for the experts. If you need to do shunting with e.g. a class 37 or class 31 , you may need to run around and so reverse. You can do it in the lazy way, just set the reverser backward, but how does this work in real life? Is the driver expected to to do a full change cabs procedure? Driving backward over some distance is dangerous because you do not have any sight on what is behind you, or is there a shunter (not sure this is the correct term) that is on watch for you using radio contact?
