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.
