Will my MTH Premier 3-rail O-Scale SP 4449 run on Atlas 3-rail track.

The only thing that I could see being a problem is if your curves are too tight. That would apply to track by any manufacturer. Provided that the curves are broad enough, there is no reason that I know of that any locomotive can not run on any track (assuming both are of three rail design of course)
