Ralph Walker is 64, retired from the Smithsonian Institution as a computer programmer, with a

particular interest in Switzerland and Swiss narrow-gauge railroads. With his wife Jan he has visited Switzerland 24 times and maintains a web site with Swiss photos (especially train photos) at www.gruetzi.com
(Editor: The cow picture is my favorite!)

He has been involved in model railroading for 10 years, and is more interested in design, control systems and tinkering than in scale modeling or gardening. His outdoor layout in Arlington, Virginia is an elevated platform with 4 concentric oval tracks.
