Memorial Day has always been a time to honor the departed. For many decades in San Francisco, thousands of people paid their respects by streetcar. From 1902 until 1949, the 40-line ran out Mission Street and continued south all the way to San Mateo, passing the cemeteries of Colma along the way. So many riders would head for the cemeteries on Memorial Day that extra streetcars would be added, many of them running on an extended version of the 14-Mission line or (like the streetcar pictured around 1940 in Colma) a shortened version of the 40-line.
