Britain used Roman numerals to denote Marks (i.e. models) of ordnance. Hence these were the third model of 14-inch gun in British service.〕 naval guns mounted on railway carriages, used on the Western Front in 1918. The guns had a very brief service life and were scrapped in 1926, but their railway carriages were re-used for mounting guns in World War II. ==Design and development== The guns were built by Armstrongs (Elswick Ordnance Company) and were originally intended to be mounted as a pair in a twin turret on the Japanese battleship ''Yamashiro'' but the order was not completed. Hence the breech of the left gun, which became known as "Scene Shifter", opened to the left which was unusual for a British army gun, while that of the right gun, "Boche Buster", opened to the right.〔Hogg & Thurston 1972, Page 196.〕 Work on mounting them on railway carriages began in 1916 but was not completed until 1918. The gun was fired from curved sections of track off the main line which allowed it to be pointed in the required direction, and the gun mount could traverse 2° left and right for finer adjustments. To adjust more than 2° the entire gun car was moved forward or backward along its track. The railway mounting was of the "cradle and rolling recoil" type : the gun was mounted high up in a standard cradle with hydropneumatic buffers which allowed the gun to recoil 34 inches on firing at maximum elevation without striking the ground, and the remaining recoil force was expended by allowing the entire railway car to roll backwards 20–30 feet until stopped by its brakes. The gun car had a winch at the front attached by cable to a strongpoint further ahead, and the winch dragged the gun car back to its firing position. The advantage of this system was that no special track preparation was required and the gun could fire from any position along its curved section of track.〔Miller 1921 pages 65–69〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「BL 14-inch Railway Gun」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
