I have a new H-10, this was my first Lionel Legacy engine.
I was having problems with the unit, not smoking flashing lights etc .... really dreading having to send it in for service.
Reading through this forum I found some useful advise and was able to reset the engine today and get her running again. Then after a few minutes she starts smoking.... pressing my luck I tried the whistle steam and for first time saw smoke from that option.
Thank you to all those who provide helpful insight
