All features on my Dreyfus Hudson worked this summer (I run DCS). After many months on the shelf I recently tried to fire her up. Initially the sound / lights / smoke came on as expected, but after a few brief seconds the sounds and smoke quit. All other features work fine including the lights and basic operation (the loco runs fine otherwise in DCS). I made sure the wireless drawbar was connected well at both ends, but that did not help. Any suggestions for how to get the sound and smoke working on my Dreyfus Hudson? I purchased the model less than a year ago from Trainworld so it should be under warranty from MTH correct?
