I had no problems with my original Precision Craft (now Broadway) GN E-7's one DCC one not. DCC loco is slower on DC layout,but sound works fine. I recieved two Broadway DCC UP E-8/9's. On Wasatch N Scale club layout at last show they ran very slowly on DC power hesitated at some spots on the layout and did not pull a 12 car train very well. Contrast this to running them in DC on my medium size home layout "Go Figure!' They start slowly,but diesel and brake squel sound work, they run smoothly with no stalling and they pull a dummy B and 12 cars no sweat. I have had no dealings with Broadway,but have to assume they will make it right. Nate Goodman (Nato). Salt Lake,Utah.
