The Los Angeles Live Steamers Railroad Museum (LALSRM) is a non-profit public-benefit corporation founded in 1956 by live steam enthusiasts for the purpose of educating the public about railroad history and lore, and to promote live steam and scale model railroad technology. The museum is located in Griffith Park in Los Angeles, California and is open from 11 a.m. to 3 p.m. every Sunday weather permitting. In 1956, all of the model locomotives were steam-powered, hence the name "Live Steamers". Over the years, gasoline-powered models of diesel locomotives and battery-electric locomotives and trolleys have also become popular. The museum operates a 7+1⁄2 in (190.5 mm) gauge miniature railway on which these locomotives pull trains that the public can ride.
The museum also has multiple smaller gauge railroad layouts for members usage in 4.75" gauge, 3.5" gauge, elevated 1 gauge, and g-scale. In addition to live steam layouts, the museum also operates a stationary 19th century steam plant every 3rd Sunday with a variety of vintage restored steam appliances. The museum hosts two live steam gatherings per year for visiting live steam hobbyists, the Spring Meet on Memorial Day Weekend in May and the Fall Meet on the first weekend of October. The museum has also hosted a number themed fundraisers and charity events over the years for Halloween, City of Hope, PADRES Contra el Cancer, and many organizations.
The museum also hosts exhibits related to Walt Disney and his passion for trains, including a full-size barn once located on the ridable miniature Carolwood Pacific Railroad in his backyard. The Carolwood Society, a separate entity from the Los Angeles Live Steamers Railroad Museum, provides volunteers to host the Disney-related exhibits. Walt Disney's Carolwood Barn is referred to by the Carolwood Society as "the only free Disney attraction in the world".
