1949 gas-powered fire engineSan Franciscans gathered Tuesday to mark the 100th anniversary of the great earthquake of 1906. In front of City Hall, fire engines from the County of Los Angeles Fire Museum commemorated the firefighters who worked to save the city.
This 1949 gas-powered fire engine is a self-contained triple combination truck that carried ladders, water and hoses.
In the mid-19th century, firefighters used draft horses to pull steam-powered engines. The first self-propelled fire engine was built in 1841, but didn't become commonplace until much later.
