This may be a better question for the DCS forum but I figured I'd check here first...
I've got an MTH/LionelCorp 4696 Brass Piper (Protosound 2) on the Christmas layout right now. I fired it up this afternoon and noticed the smoke unit fan was running really loud with the engine idling. It's smoking at max and doesn't seem to let up. If I turn off smoke via the DCS remote then the fan stops, as expected. If I leave smoke on and get the engine moving forward it smokes normally, with only intermittent smoke fan pulses in sync with the speed. But once the engine stops, the smoke unit fan spins up to max and it smokes continuously.
This isn't normal, right? I don't remember the engine doing this before. But my kids (whom I love *ever* so much) sometimes operate the trains and don't always do a great job shutting them down properly. I'm wondering if something got a little messed up here. I tried doing a factory reset on the engine via the DCS remote but that didn't change anything. Am I imagining this? The engine shouldn't be smoking forever at idle, right? Any other suggestions?
