A railway gun, also called railroad gun is a large artillery piece, designed to be placed on rail tracks. 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. Some of these were so large that they required two parallel sets of tracks to support the gun.

A railway gun, also called railroad gun is a large artillery piece, designed to be placed on rail tracks. 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. Some of these were so large that they required two parallel sets of tracks to support the gun. Smaller guns were often part of an armoured train.
Railway guns (like their seagoing analogues, battleships) have been rendered obsolete by advances in technology. Their large size and limited mobility make them vulnerable to attack, and similar payloads can be delivered by aircraft, rocket, or missile.
History
19th Century
The idea of railway guns appears to have been first suggested in the 1860s by a Mr Anderson, who published a pamphlet in the United Kingdom titled National Defence in which he proposed a plan of ironclad railway carriages. A Russian, Lebedew, claimed to have first invented the idea in 1860 when he is reported to have mounted a mortar on a railway car. The first railway guns were used by Robert E. Lee when he used a 36 pounder mounted on rails to interfere with General George McClellan's plans for siege operations against Richmond during the Union advance up the peninsula during the American Civil War. France also used improvised railways guns during the Siege of Paris in 1870 and the United Kingdom mounted a few six inch guns on railway cars during the First Boer War intending to bombard forts around Pretoria, but Pretoria was captured before they could be deployed.
In France, Lt. Col Peigné is often credited with designing the first railway gun in 1883. Commandant Mougin is credited with putting guns on railcars in 1870.
The French arms maker, Schneider offered a number of models in the late 1880s and produced a 120 mm gun intended for coastal defense, selling some to the Danish government in the 1890s. They also sold a 20 cm model to Peru in 1910.
World War I
The outbreak of the First World War caught the French with a shortage of heavy field artillery. In compensation, large numbers of large static coastal defense guns and naval guns were moved to the front, but these were typically unsuitable for field use and required some kind of mounting. The railway gun provided the obvious solution. By 1916, both sides were deploying railway guns. The most famous railway gun of the war is probably the Paris Gun.
Baldwin Locomotive Works delivered five trains for the United States Navy during April and May 1918. Each train transported and supported a 356mm naval rifle mounted on a rail carriage with four 6-wheel bogies. These guns were the Mk 4 14"/50 caliber guns used on New Mexico and Tennessee class battleships. The locomotive, ammunition cars, supporting equipment cars, and accommodation cars for the crew were under the command of a United States Navy lieutenant, and under overall command of Rear Admiral Charles Peshall Plunkett. After delivery by ship, these trains were assembled in St. Nazaire in August and fired a total of 782 shells during 25 days on the western front at ranges between 27 and 36 kilometers. The railway carriages could elevate the guns to 43 degrees, but elevations over 15 degrees required excavation of a pit with room for the gun to recoil and structural steel shoring foundations to prevent caving of the pit sides from recoil forces absorbed by the surrounding soil. The train included cars to transport recoil pit foundations constructed by Baldwin. One of these guns is on display outside
the museum at the Washington Navy Yard.
Baldwin constructed six similar gun carriages and two of an improved Mk II type designed to permit firing the gun at all elevation angles without transferring weight to a separate foundation. These eight guns were completed too late to see combat, although some were stationed through World War II in special coast defense installations at San Pedro, California (near Los Angeles) and at the Panama Canal Zone where they could be shifted from one ocean to the other in less than a day. Improved carriages were designed to allow transport to several fixed firing emplacements including concrete foundations where the railway trucks were withdrawn so the gun could be rapidly traversed (swiveled horizontally) to engage moving ship targets.
The United States constructed approximately fifty smaller depressed center railway carriages on two 6-wheel bogies for 203mm naval rifles made surplus by the Washington Naval Treaty. Approximately a dozen of these were used for the defense of Oahu. Others were stationed through World War II for coast defense of Manila, Bermuda, Newfoundland, Puget Sound, the Columbia River, Chesapeake Bay, Delaware Bay, and Fort Hancock, New Jersey (near New York City).
World War II
The Second World War saw the final use of the railway gun, with the massive Schwerer Gustav 800 mm gun, the largest artillery gun to be fired in combat, deployed by Germany. The rise of the aeroplane effectively ended the usefulness of the railway gun. Similar to stationary battleships, they were massive, expensive, and, in the correct conditions, easily destroyed from the air.
Both Germany and Great Britain employed railway-mounted guns that were capable of firing across the English Channel between the areas around Dover and Calais. Germany employed a number of 40 cm guns. Britain employed three railway mounted guns on the East Kent Light Railway, located around Lydden and Shepherdswell. These were known as Gladiator, Sceneshifter and Piecemaker. 9.2 inch Mark 13 guns were located near Canterbury and Hythe; an 18 inch Howitzer, Boche Buster, sited on the Elham Valley Railway, between Bridge and Lyminge; and 12 inch howitzers, Mk 3 and 5, located around Guston.
