Looks like an effort. But, if you had 100 guests (non-train nerds) view the board, I would imagine that there might be 2 who actually noticed the difference in the new vs. the other. Just an opinion from viewing my guests, and those that I have been with at other open house viewings. Kind of like putting passengers in cars- I do it, but I realize, most people never notice them! Good luck with your efforts, looks nice, but I think it needs to a lot "dirtier" to look closer the real stuff around here. Tracks seem to be mostly rust. and most ballast seems to be dark gray to black!
