San Diego County Municipal Code · 2026-09 edition · updated 2026-10-02 · San Diego County
9.3.1 Existing Uses¶
PSRM houses over 80 pieces of railroad equipment, including steam and diesel locomotives, passenger cars, freight cars, and cabooses within its approximately 128.98 acre grounds located in the northwestern portion of Camp Lockett. The PSRM site currently includes the restored Campo Depot, which functions as a train station and gift shop, and includes exhibit halls and display areas showcasing historic railroad cars and locomotives, as well as the Southwest Railway Library. Other facilities include a display area, library/theater, train depot, restroom, rental house, and horse barn. PSRM receives approximately 15,000 visitors per year and operates three trains using diesel-electric, each Saturday and Sunday. The train rides travel four miles one-way, with between 12,000 and 15,000 rides provided annually.
9.3.2 Planned Uses¶
PSRM intends to expand the existing Campo museum and preserve and maintain nearby open space areas adjoining the historic SDG&E rail line. The property is unimproved, except for storage tanks that were formerly used for a propane distribution system.
Figures 9 and 10 classify the constraints related to the PSRM Planning Area into the following five categories: no impacts, potential issues that require additional analysis, potential issues that involve higher level of analysis/difficulty, potential significant impacts, and significant impacts – no build possible. Constraints were generated from a variety of sources including available GIS files, field-verification, and surveys. Constraints such as cultural resources, archaeological resources, biological resources, vegetation, steep slopes, 100-year floodplain, and liquefaction were evaluated. Once constraints were identified, Figure 11 and 12 were developed to depict the zones governing the site.
The PSRM Planning Area is divided into the following four subareas:
