Nice work. it's very cool of you to build this in his honor, and to share it with others.
The Thompson River Canyon layout is done. Well, half of it; I ran out of time to do both sides of the 2 x 7 portable layout. But it is now ready for display at this weekend's train show in Winnipeg, in honour of my brother-in-law, Ken Epp, who died last October before he could build his own version of this, his favorite railfan location.
In this last post, I describe how I painted the canyon and the water. There are links in the articles to all 6 posts, so you can follow along from start to finish.
