As info, I also ran the same size 2 rail freight train on my 3 rail layout, and it was over 2 dB quieter, and indication to me that the 3 rail sintered iron wheelsets originate most of the noise, with the engine's pickup rollers adding the rest...
There have been several "which track to use" threads over the years. My recommendation has been Atlas 3-rail track with Ross turnouts. At the club, I run quite a bit of scale-wheeled equipment and I rarely get derailment issues with Atlas, MTH 2-rail and Weaver trucks (Intermountain wheels) UNLESS there's a gauge problem. Code 145 wheels will have issues if something is out of gauge. If you use the Ross #4 and 11-degree (#5) turnouts things should work pretty well. Atlas track and basic Ross turnouts are also insulated, so you can wire for 2-rail operation if you'd like.
MTH ScaleTrax, though a little harder to get, is also 2-rail compatible. The layout I'm working on right now will be using ScaleTrax. It's also quiet because it has smaller scale-profiles Code 190 rail and smaller ties. On the turnouts, you might want to make sure to insulate the frog from the closure and stock rails just in case something shifts.
Hope this helps.
