I,am not sure if I,am doing this right but I guess I won,t know unless I try. I model the Toronto Hamilton & Buffalo RR (TH&B) in Ho gauge in mid 1950,s I have been working on my layout off and on for a few years but now that I retired I should more time. Computers are new to me and just discovering these forums I think they are great. there is so much info out there and no matter how long your in the hobby you are never to old to learn from others.
