No Ron you are confusing rail guns with railway batteries. Railway batteries were artillery usually of about field gun to medium size mounted on railway trucks often armoured, and used to cover a section of the front or coast. The French were great users of these and I've posted a photos earlier in the thread. There were usually two or three guns per battery. As I've also said earlier in the thread soldiers often conflated rail batteries and armoured trains. The big rail guns were as you say usually over 9 inch and quite a different matter. Again as you seem to have missed I also covered some of the recoil issues earlier in the thread. Only the the French allowed them to recoil back along the track (as I said about 2 metres). German and French railguns had a proper recoil mechanism and many German rail guns were mounted on a turntable fixed in the ground and the railway trucks completely removed for firing. The Turkish mobile batteries were railway batteries, NOT rail guns, running on sections of track probably just long enough to cover the area they were protecting. They appear to have been under the control of the Fortress commanders. Interestingly some Turkish fortesses had Gruson mobile turrets (Fahrpanzers) which ran on 60cm track and I wondered if some of these were linked together to run on the narrow guage track that is photo'd near the major Fortress of Kilid Bahr. With a QF 6 pounder these would have been ideal for engaging the mine sweeping trawlers.
are talking about two slightly different creatures here. The first, the armoured train proper, was equipped with guns of 6-inch calibre or less, and usually also with machine guns. It was used to protect rail communications from raids, and occasionally to provide a mobile response to attack, especially along coastlines or borders. The British used small numbers of these trains in France and Belgium, Egypt and Palestine, and Mesopotamia. They were also used in the South African War and in India.
The second type is rail-mounted heavy artillery, of calibre 9 inches and more. The history of these weapons is covered in Rail Gun by Ian Hogg and John Batchelor. It provides a number of interesting photos and scale drawings, and also covers such points as the use of curved gun spurs (plus a limited degree of traverse on the mount itself) and the various methods of absorbing recoil (using outriggers to anchor the gun, often including jacking up the wagon to lift the wheels from the track). It covers the period from the American Civil War to the Second World War, and includes American, British, French and German examples.
The authours assure us that the use of the recoil to send the loco back along the track, to return carrying tea and rations, is apocryphal!
