John I was thinking of your Phantom when I wrote my post. Unfortunately there's no way Scott can get a second motor in a Geep. But if his layout is 8x8, two single-motored locos should pull enough cars to wrap the layout.
IMO "dummies" are just that-dumb. If you're not going to put a motor in the dummy, then I would forget the Lionel. Buy a Williams "clone" and wire the motors in series for better control. My $.02.
