Hello John and others. Noticed the nice guard rails above, which are not a stock option for out of the box track (like Atlas). Prototypical question: when are guard rails usually implemented? Bridges, tunnels and crossings mainly? I don't see any of these in the gorgeous photo above, but maybe they are just slightly out of shot. Anyways, I think it really adds to the realistic look of the track.
