This is a picture I've posted before, though I've actually added weight to a bunch of different locomotives. The before and after for this unit was like night and day. I added a bit over a pound of weight near the trucks, and this went from an anemic puller to a robust locomotive. It was having trouble pulling five 18" cars on a 2% grade, after adding weight it was hauling a dozen cars the same grade without any issue.
BTW, it already does have traction tires, so weight is certainly a major factor.
