There was about of standard gauge railway line within the perimeter fence. The factory had its own fleet of nitric acid wagons and diesel shunting locomotives. The latter were used to move wagons between the transfer sidings and various locations within the site. In addition, ROF Bishopton had some of narrow gauge railway lines for transporting explosives around the site. There was a large fleet of rolling stock and a specialist workshop for maintenance of the locomotives, which were kept in excellent mechanical condition. Much of Bishopton’s narrow gauge railway equipment still exists, and can be seen at locations such as the Almond Valley Light Railway (six assorted locomotives) and the Amberley Museum Railway (locomotive No. 12 and several wagons).
