railway gun
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.
Not to be confused with railgun.
