That is the same place I've arrived, I've just had a hard time finding the time to implement the layout portion. Been slowly collecting the equipment since 2012, but need to find the time and figure out how to fit a 2 rail layout into my space. I do so hate duck unders and all the 2R is roughly mid 50's NY&LB based - CNJ / PRR. I think I can get away with an 48" radius on the inside track. That might work. And since it is a commuter road, It will be a loop with two mainlines like the real road with the various turnouts that served some of the industries along the way on the minimal freight service the PRR and CNJ provided.
I picked up an old Brass Alco NE5 New Haven caboose at a show a many years ago for $50.00 and it is gorgeous. The scale flanges sold me.
My home 3R layout is just simple modules that were given to me. A nice running layout, but nothing special in terms of the true art of model railroading. Since I won't be able to build what I want for a while, my 3R club has a wonderful scale oriented layout that is very enjoyable regardless of how many rails it has. It is not Kadee friendly though. I've dropped a few too many passengers at prior to their destinations in the dips.
