540 came down and entered the loop, we stood over it and saw the locomotive disappear under our bridge, then in a few moments appear again, chasing its own tail; and we saw it gain on it, overtake it, draw ahead past the rear cars, and run a race with that end of the train. It was like a snake swallowing itself.
