The ’20s & ’30s Modular Model Railroad recreates the Golden Age of railroading modeled in 1:87 HO scale. Members build and transport their own six-foot-long modules which depict North American railroading during the period from 1920 through December 7, 1941, Pearl Harbor Day. Started in 1991 by Charley Hepperle, the club’s members have built over three dozen modules, which will be on display at the National Model Railroad Association’s National Model Train Show in Anaheim, California July 18-20 2008. Each module or group of modules meets standards for interface such as rail location, height and electrical connections so that each can connect with another. The club sets up at public shows in Southern California about six times a year.
