Just exiting the curve and prior to the first Kellogg Camp Switch, there is a defective track segment causing derailments. I found this using the new “Free Roam Sultan Foresty – RS-1” scenario and i’ve tested it multiple times in the last couple of days. Any attempt to enter the yard at ‘posted’ speed limits will cause a derailment. The RS-1 will make it if you crawl (1-2mph) and the BLE 0-6-0 will at 5-7mph.....but just barely.
Hope this helps
