When we run at Pershing square, we rotate the trains out after about an hour since there are a few of us running. I typically bring multiple trains. Running for four hours once in a while is OK provided the locomotive is properly lubricated, not run too fast, not overloaded, and the smoke unit is off or refilled as needed. I did lose a speaker on a 5-volt GP7, though, but that's unrelated to the run-time.
