The Pacific Southwest Region of the National Model Railroad Association (NMRA) consists of four Divisions in the Southwestern United States. Click on the divison logo to the left to go to the selected division website.

  • The Arizona Division covers the state of Arizona
  • The Los Angeles Division covers the Metropolitan Los Angeles area, Ventura and Palmdale to the North, and Claremont to the East
  • The Cajon Division includes Orange County, San Bernardino County, and Riverside County, in California, and Southern Nevada
  • The San Diego Division covers San Diego and Imperial Counties

Each Division has its own meetings and activities. Those activities include visiting model train layouts of the Division members and of model train clubs in the area.  The meetings can be very informative for the model railroader and most Divisions include clinic presentations at their meetings covering modeling topics such as weathering model railroad cars and building structures for model layouts. Your membership in the NMRA will bring you a wealth of knowledge about model railroading and improve your techniques in building a model railroad layout.
