Thank you Ron That describes what happens to me, I keep all my sounds at 20%, smoke set to light.
Another thing that happens everyday with single locomotives and MU, after shut down the next startup... engine sounds and accent sounds go from 20% to 70% and sometimes smoke from off- to- on.
When running if power is cut for any reason the locomotives lock up tight !! what happened to 1960 technology of flywheel coasting drive ? they use to coast.
