A railway gun, also called a railroad gun, is a large [[artillery]] piece, often surplus naval ordnance, mounted on, transported by, and fired from a specially designed railway wagon. Many countries have built railway guns, but the best known are the large Krupp-built pieces used by Germany in [[World War I]] and [[World War II]]. Smaller guns were often part of an [[armored train]].
