Thank you Sully & RTR12 for the kind words.
I did learn a lot from this forum after starting my layout. From the beginning I knew I wanted to focus on the NYC Grand Central Terminal with as close a copy of the Met Life building behind the GCT. I am pleased how that scene turned out. I also knew what trains/accessories I had collected thru the years, therefore I wanted to use as much of my collection that I could. I accomplished using a lot, but I ran out of space. I also knew I wanted 3 mainlines to enable running a minimum of 3 trains at once. I can run 6 fairly long trains. I also knew I wanted as many yards I could squeeze into the plan to enable storage of cars/engines. I have some long yards, but I wish I had more. Backdrops were my hardest thing to find. I knew what I wanted, but couldn’t find it. What I ended up with is close.
I have been lucky to find vendors who helped me with accomplishing my wishes.
I basically knew what I wanted from the beginning, and for the most part have to date accomplished my wishes.
