World War I railway gun
World War I railway gun
During World War I surplus Modèle 1893/1896 guns were mounted on both rotating centre-pintle, cradle recoil, and sliding-carriage mountings on railway carriages to provide mobile firepower on the Western Front. They fired shells weighing from 321–351 kilograms (708–774 lb) to a maximum range of 31,130 metres (34,040 yd). The railroad mounts had a maximum elevation of 40° which accounts for the extra range over the naval guns.

Description
The 12-inch/40 calibre Canon de 305 mm Modèle 1893/96 gun was a typical built-up French heavy gun of its period. It used a Welin interrupted-screw breech and bagged propellant with a de Bange obturator to get a good gas seal during firing. It was mounted in twin-gun turrets which had a couple of unusual features. First, most of the turret's operating machinery was housed inside the turret, with only an armored tube to protect the ammunition hoists. This made little difference in the overall weight of the turret, but did raise the machinery higher in the ship than the turrets of other nations, which did have implications for stability. Secondly, they used a hydraulic pivot to lift the turret when it rotated; this was lowered onto a seating ring when the turret was in the proper position to fire. Each turret had a nominal 300° of traverse, although each ship had its own specific limitations.
