Arizona Big Train Operators was formed in the mid-1990's to promote the hobby of "G" (garden) scale model railroading in Arizona. Over several weekends each December, the members make their backyard layouts available for public viewing during the organization's Holiday Open House Tours. The displays are incredibly large and detailed, including a variety of tiny rail yards, lakes, mountains, bridges ... and towns. These photos, taken during the 2009 open house, show a few of these tiny towns.
Directions: Various private residences in the greater Phoenix area. For location maps and hours, go to the Arizona Big Train Operators web page and click on "Holiday Tours." No admission fee is charged, but donations for charity are accepted.
Last visited: December 2009.
