I was watching a DVD the other day which had the RHTT in it. For such a small train both locos were in power. Why is this? You see this all over the place. Topping and tailing. Why does the rear loco have to be working? This is surely a waste of fuel. They can turn it on when they need it. Is there a reason for this?

Best regards.
