Tiny trains are back! Hosting its first model train show since March 2020, the 74-year-old Columbia Gorge Model Railroad Club is once more giving tours of its 2,000-plus-foot network of double-laid track. CGMRC owns the largest model train layout in the Pacific Northwest. Painstaking models of track to Wishram, Wash., and Bend include a miniature steel arch bridge that spans the mouth of the model’s Deschutes River and a tiny but bright neon stag sign that lights the model’s downtown. The show concludes this weekend, but there are more opportunities to see the collection by making a reservation for Saturday or Sunday, Dec. 4-5.
