Lou1985 Thanks for telling about the Lionel Consolidation.I was thinking getting one but you mentioned about it being a weak puller, you've saved me some money.
I have the earliest release of that locomotive (Southern Pacific, TMCC) and it pulls ok. It manages a freight train of 10-12 scale cars with easy and will pull 3-4 heavyweights fine. I wouldn't expect it to do more than that being that it has a small RS385 motor. The MTH Pacific on the other hand should have no problems with a 8 car or more heavyweight passenger train or 50 freight cars. It's just a larger, more powerful locomotive.
