The original group was started by local Southern California model railroad manufacturers in the early 1970s, as a way to display their products at hobby shows. Organized as the Southern California Module Builders, the club met at the Campbell Scale Models factory. They displayed their first operating modular layout in 1973. At various times in the club’s history it was known by several different names, including The Orange County HO Modular Group and Module Railroaders – Orange County Division. In 1997, we streamlined the name to simply Orange County Module Railroaders.  We are often referred to as OCMR.   In 2005, A separate corporation, Orange County Module Railroaders, Inc. was formed as a nonprofit, nonstock mutual benefit corporation and the assets of the original club transferred to the corporation.

We continue taking the hobby to the public, setting up operating displays at museums, fairs, seasonal exhibitions, model railroad shows, conventions and home shows throughput Southern California.

Ask any member about the unique advantages this form of module railroading has to offer — beyond a static display.


Our club has two regularly scheduled meetings each month except for December where there are no meetings scheduled.

The first is our regular business meeting on the SECOND Tuesday of each month, held at the Duck Club at Irvine Ranch Water District (click here for map and directions).

The second is the meeting of our Executive Committee (also called “the E-board”) which meets at Denny’s in Tustin (click here for map and directions) on the last Tuesday of the month.  

Both of these meetings start at 7:00 p.m..
