They piled on more coals, shovelling furiously; the furnace roared, the sparks flew, the engine leapt and swung, but still their pursuers slowly gained. The engine-driver, with a sigh, wiped his brow with a handful of cotton-waste, and said, “I’m afraid it’s no good, Toad. You see, they are running light, and they have the better engine. There’s just one thing left for us to do, and it’s your only chance, so attend very carefully to what I tell you. A short way ahead of us is a long tunnel, and on the other side of that the line passes through a thick wood. Now, I will put on all the speed I can while we are running through the tunnel, but the other fellows will slow down a bit, naturally, for fear of an accident. When we are through, I will shut off steam and put on brakes as hard as I can, and the moment it’s safe to do so you must jump and hide in the wood, before they get through the tunnel and see you. Then I will go full speed ahead again, and they can chase me if they like, for as long as they like, and as far as they like. Now mind and be ready to jump when I tell you!”
