Some of you are probably aware of the site already but Mr. Tony Cook has assembled a wealth of reference material pertaining to model trains in a variety of scales. Originally dedicated to HO equipment, he is now expanding coverage into N and O as well. Included are pictures of the models themselves accompanied by in-depth descriptions, copies of advertising materials and catalogs. It's well worth perusing and will bring back fond memories for folks who have experience with the models described.
