There are a lot of great layouts in Canada. One of the best, in my opinion, is the Kicking Horse Pass layout of Calgary. What makes this 24 by 42 foot representation of the CPR's world-famous Spiral Tunnels all the more amazing is the the layout is portable.
I was fortunate enough to bring it to Winnipeg in 2005 for Golden Rails, the 50th anniversary of the Winnipeg Model Railroad Club; I have posted some photos and information about this remarkable layout on my blog at
