The Pacific Southwest Region of the National Model Railroad Association (NMRA) consists of four Divisions in the Southwestern United States. 

• 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.

Pacific Southwest Region Convention

The biggest annual event for the Pacific Southwest Region is the regional convention. Any NMRA member is invited to join us at the 2022 PSR convention, as are members of the public. The convention has many model railroad activities including an array of clinics, prototype tours, contests, layout tours and a swap meet. The next convention, Back on Track in 2022, is September 7-11, 2022 in San Diego, CA.
