Humongous Moves S01E03 - Gigantic Gun

A 200-ton WWI howitzer needs to be transported to a museum nearly 400 miles away in less than a week. The BL 18-Inch Railway Howitzer, displayed at the Royal School of Artillery in Larkhill, England, is the world's largest surviving railway gun. It is the only remaining one of this type out of five built and fires an 18-inch, one-ton shell almost 13 miles. The Spoorwegmuseum, the Dutch national railway museum in Utrecht, Holland, borrowed the gun in March 2013.
