I originally posted these pictures on my old website on January 7, 2007, as part of my “The Life & Times of A.C. Gilbert” feature.
In 1984, the "Holidays at the Capitol" decorating committee at the Oregon State Capitol commissioned the Vocational Training Section of the Oregon State Correctional Institution to build a winter-themed model railroad for use as part of the holiday decorations in the rotunda of the state capitol building. This layout uses American Flyer S-Gauge trains and features models of historic buildings from the Salem area, including A. C. Gilbert's childhood home and the home of his uncle, A. T. Gilbert. This layout appears annually in the rotunda of the Oregon State Capitol building during the month of December, and at other model train shows in the state throughout the year.
Here are pictures and a video of the layout in the rotunda of the Oregon State Capitol building on December 22, 2006.
