Looks like a great layout in the making, thanks for the link.
That line is close to home for me: my brother-in-law lives in Slocan, and my mother was born in Rossland and grew up in Trail (Tadnac) while her dad worked at the Cominco smelter. I remember many a summer in the late 60's heading up that way for holiday. We'd stay in Trail for a few days (I spent most of the time watching CP switch the smelter) then head up to Christina Lake. Good times.
