Seeing as how the track is now down on the main board, (got to do the end wings yet) I thought I would give my loco's a test run to see if the grades weren't too steep. All loco's pushed up six empty log cars with no problem, but three is all that will ever run. The Climax has just made the easy 4% grade climb, and the Shay is pushing up three cars on the 8.5%. This is the grade I was worried about, but all is fine. The tracks here are the upper two levels out of four. Shamus.
