Hello Guys
I also use ATLAS TWO RAIL track in my NY City based Elevated Transit Line. In my yards I did use some brass rail on fiber tie track (as the track is hidden by lay-up extra trains most of the time) and in some places I cut and made my own ties and hand spiked-down rail to make tracks in another yard. I find ATLAS O-Scale (2 or 3 Rail) is the best looking track around for subway and elevated and surface R-o-W rapid transit (or interurban) based layouts. The tie "wood grain" detail and tie plates, spike heads, etc., make for increased realism. My curved track have additionally installed by me, both working "flange" check rail and outer safety guard rail - as well of course, the outer wood guard timbers used on all older era tracks on the EL. See my photos BELOW attached taken on my EL layout.
