Anthony,
I've found a bug for you. Neither the Wolverine nor the Twilight Limited recognize Pontiac Michagan as a valid destination. However I can assure you that Pontiac is indeed a valid destination, as I rode out yesterday on the Wolverine and returned on the Twlight.
I did not check intermediary stations on those routes to see if they worked or not.
