Very nice, I never heard of Sn3 before, but thats why I joined the board, to learn new things. I only remember the old Lionel Flyer S gauge trains.
I have always admired Sn3 modelers. They are kind of like a breed of their own. I have often said to myself that if I ever switched out of N scale, that I would go into Sn3 in a heartbeat. Great Job! Keep up the good work. Looking forward to seeing more pictures of your layout!
