Trying to perfect an engine spec for the Pennsylvania Railroad S1 (Part 2)

[ChugLifeBoy]

Hey, everyone! I wanted to ask to see if anyone could give me some helpful information on the Pennsylvania Railroad S1's configuration stats so that I can make its Engine Spec as accurate as possible! Since I'm trying to make it as accurate as possible, I'd appreciate it if you guys gave me not only some helpful and important information about the S1's configuration stats but also some very detailed instructions on how to apply those stats to the Engine Spec. I look forward to seeing the information you all have for me and I really appreciate any help I can get because I'm not the best at working with Engine Specs.

This is what I found, hope it helps:
"The S1 was designed to haul a 1,200-ton (1,089-t) passenger train at 100 mph (161 km/h). The engine developed around 6,500 indicated hp (4,847 kW) at 100 mph (161 km/h) and had a maximum tractive effort of some 76,400 lbf (339.8 kN) based on an 85% efficiency factor.
