New oversize trailer for war workers. Interior of the new oversize bus trailer, built almost entirely of non-critical material and designed by Office of Defense Transportation and War Production Board (WPB) officials with cooperation of private companies. Containing eighty-seven fixed seats (twenty-four drop seats will be installed later), the trailer has a seating capacity nearly three times that of an ordinary city bus and twice that of the largest type of street car. It's one solution to the problem of transporting defense workers from cities to outlying industrial plants. Sourced from the Library of Congress.
