Welcome to the Pacific Southwest Region of the National Model Railroad Association

The Pacific Southwest Region (PSR) officially began on June 1, 1982. Originally part of the Pacific Coast Region (PCR), the Region consists of four Divisions; Arizona, Cajon, Los Angeles, and San Diego covering the entire state of Arizona and the southern portions of California and Nevada.
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.
