So I have recently started to write a review of K&L Trainz Frisco 1522, but I have hit a snag. I wanted to emphasize just how powerful the 1522 was during her last excursion on September 29, 2002. She pulled 30 cars (if you count the Amtrak P42 and the Auxiliary Tender) unassisted between St. Louis to Newburg. She was rated to pull only 26 passenger cars so pulling 30 cars on what was classified as a helper subdivision by the Frisco Railroad is pretty impressive. I know this division was classified as a helper division but I have no idea what the grade profile was. I was hoping that someone here could help me.
