The MTH Big Boy can has a pull force of about 7.5 to 8lbs which is very strong.  As I recall we had 120 coal cars connected to a single engine on one of our trainshow displays on oval with 20' diam curves.  So what the maximum would be I'm not sure.  My drawbar tests on the USA Big Boy was about 8lbs pull force (reason MTH pulled so well in comparison is the MTH has traction tires where the USA has all Stainless steel wheels which is a hard and more slippery metal.)
