Using the Shay locomotive, with easy controls activated, I was doing a saved activity which I had climbed up hill (with just engine & tender) to the Zinc #1 and Zinc #2 sidings. As I let off the regulator, at some point the engine began to drift backwards down the hill, which makes sense. I tried to apply the locomotive brakes (using the keyboard commands) but they would not apply, likewise with the train brakes (even though there were no cars), still no luck. Meanwhile the engine is rocketing down the hill in reverse. Since the activity is saved, I tried numerous times with the same outcomes.
Am I doing something wrong that the brakes won't apply, or did something glitch during the save process?
