Thanks Jeff.  I do run DCC but have not changed any decoder settings.  I'll take all your suggestions and see what happens.  Appreciate the help!  I should say that at very slow speeds (at which I prefer to run the trains) the noise is considerably less and tolerable.     

I have a brand new Forney with about 8hrs of running time.  It tracks like a champ, just crawls along steady and smooth.  However, in forward motion there is a very loud almost static like sound.  I can't determine if it's electrical or mechanical in nature.  It is much quieter in reverse.  It's becoming so loud that even with the sound turned on I hear the noise.  Any thoughts?
