Hello all.
I am beginning to plan a new layout in N and will be moving from HO to accomplish this.

I am curious as to the expieriences of other users and what brand and code of N to use.  I know that with my old HO set (all Fleischmann) there were issues of some brands of rolling stock and locos not accepting the Fleischmann track very well, and want to avoid any potential problems before they happen

Because it is so readily available, and somewhat reasonably priced, I am considering using Atlas track, however the code to use remains elusive at the present time.  Tru-Track seems to optimim as far as being realistic, but beyond that, would I be better off with 55, 80 or 83?   This is going to be a fairly large N scale layout measuring approximately 4687.3mm X 2438.4mm and for a large part of the track I plan on using flextrack.  I want to be sure that all of the track is capable of running different brands of rolling stock with the least chance of derailment because of the track.

Any suggestions or comments will be most appreciated.

John
