Another small update, and a few pictures to go with it. finally after trying for two weeks to sit down and test the expansion in depth in cab mode, I was able to make a few needed changes. The grade out of Timber ridge, from the timber ridge side is pretty easy to climb. I was able to take the K-28 with 10 unloaded class 6 stock cars plus a caboose up the 1.5-3.5% grade. since the grade is not constant, she gets more then enough traction going up.
The other side however, is a very different story. It is between 3.4-3.8% for the whole length, which is about 2/3 of a mile. Short, but steep, I was unable to get the K-28 up with 150 tons behind her, so I added some infrastructure in La Forge for helper locomotives (small water tower and a coal shed), and there is now a siding on the Timber ridge side to switch the helper if needed, or you can take it the whole 5 miles to timber ridge, whatever is more fun.
I am just about ready for a beta release, if anyone is interested, please PM me
