Buried trolley tracks salvaged to aid war program. Old tracks for new guns. One of the ways many American cities are responding to Uncle Sam's call for scrap is by pulling out abandoned trolley tracks. This apparatus, developed by an Asheville, North Carolina machine shop operator, is being used to tear out the old buried tracks in his city. With three men, the device can remove twenty-five tons of rail per day. Sourced from the Library of Congress.
