The Pacific Southwest Railway Museum Association, Inc. is dedicated to preserving the physical legacy and the experience of rail transportation. Programs address the historical, social, economic and technical impact of railroading with particular emphasis on railroads of San Diego County and the larger systems with which they connected in the United States and Mexico.
The Museum stresses a living history approach in interpreting railroad history to the widest possible audience. PSRM's programs are designed to increase public appreciation, education and enjoyment of the significance of the railroad heritage through:
-Operation of a demonstration railroad
-Establishment of a research library available to the public
-Educational facilities which are maintained and operated for the instruction of the public in railroad history, railroad operations and general rail transportation technology.
