A dose of nostalgia and workwear for your weekend. This 1950s film about the development of the U.S. railroad system is a great looking little piece of history. “America is the living symbol of the miracle of modern production.” Well said Mr. Industrial Propaganda Film announcer. Check out those brand new Caterpillar dozers at the 2:03 mark, the plaid work shirt at 6:19 and all of those factory scenes. Great stuff.
