Last weekend I attended the Greenberg show in Richmond, VA. Normally I don't find much other than a book at these shows, but last weekend I hit the jackpot. A dealer was selling off three BTS kits and I was happy to buy them. A wood rack (2 pack), boxcar with radial roof (3 pack) and a flat car are now sitting in my to be built pile.
Also, this week I broke down and ordered large prints of the City Point yard and the Line out to the trenches. These charts are a great resource and should allow a closer inspection of track arrangements with the caveat that they need to be cross-checked against photographs as the two don't always agree. Also, they should make great wall decorations in the train area.
I added a link to another user who is doing City Point in HO. He has done a lot of cross-checking against photographs. The plan shown on the link is over 30 ft long in HO. In O that would make mine 60 to 70 feet which is way too long for my small space. Time to rethink some of my assumptions. More on this later.
