Arizona is the largest division of the NMRA‘s Pacific Southwest Region (PSR), both in terms of the number of members and area. The division encompasses the entire state of Arizona. Any member who lists their residence with the NMRA as “Arizona” is automatically a member of the Arizona division. Being known for winter visitors, Arizona has many guest NMRA members during the season.
The NMRA is the largest organization devoted to the development, promotion, and enjoyment of the hobby of model railroading. The NMRA was founded in 1935 in Milwaukee, Wisconsin in order to provide a service to the hobby of model railroading.
