During World War I surplus Modèle 1893/1896 guns were mounted on both rotating centre-pintle (Batignolles) 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.
