IMO, a Pennsy locomotive is ideal for a coal drag.
During my summer vacations visiting my aunt and uncle in Pennington, NJ, we would hang out at the swimming pool at Hopewell Country Club while my dad and uncle played golf. At the pool, my mother, aunt, cousins and I would watch endless Pennsy coal cars roll by as they were pulled by powerful roaring Pennsy locomotives that made the ground tremble and took my breath away.
I think the love that some of us have for our model trains stems from such experiences we had as kids.
Here is an MTH Proto 2 Pennsy diesel running slow and smooth on DCS hauling Lionel operating coal dump cars:
