Welcome to the online home of the Pasadena Model Railroad Museum!

Founded in April 1940 as the Pasadena Model Railroad Club, PMRRM has been part of the model railroad community for over eight decades. PMRRM is located in Los Angeles, California (we moved from Pasadena decades ago, but the name stuck), and operates one of the largest HO scale model railroads in the world, the 5000 square foot (70′ x 72′) Sierra Pacific Lines.
