The Los Angeles Live Steamers Railroad Museum (LALS) 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 modelrailroad 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. 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 71⁄2 in (190.5 mm) gauge miniature railway on which these locomotives pull trains that the public can ride. The museum also has multiple railroad layouts with smaller gauge track.
Walt Disney's Carolwood Barn, his personal workshop building and creative space for his miniature Carolwood Pacific Railroad, was loaned to the City of Los Angeles by the Walt Disney Family Foundation in 1999. The barn, as well as a combine car from the first passenger train of the Disneyland Railroad, are located within the Los Angeles Live Steamers complex. Complementary public admission to these exhibits is available on the third Sunday of each month from 11 a.m. to 3 p.m., which coincides with LALS demonstrations of the stationary steam plant. Docents and volunteers of the Carolwood Society are on hand to answer any questions, offer informal tours, and elucidate displays about the intimate relationship Walt Disney had with railroading.
