Spanning over 27,000 square feet of trains, trestles, and tracks we are in the heart of natural beauty framed by the majestic backdrop of Balboa Park. The San Diego Model Railroad Museum (SDMRM) is a space where imagination is beautifully engineered. SDMRM features both indoor and outdoor exhibits and programming for all ages.

 Our mission is to collect, preserve, and present the heritage of American railroading with scale models of California railroads. At every twist, turn, and tunnel we spark curiosity with developing educational programming that includes education milestones like critical thinking, creativity, and problem solving. Our exhibits transform little engineers to modelers who tinker with engines and nail down track to build and transform something from nothing.
