World War 1 , Europe, Western Front, Railway Operating Division, 1918

The Railway Operating Division (ROD) was a division of the Royal Engineers formed in 1915 to operate railways in the many theatres of the war. It was largely composed of railway employees and operated both standard gauge and narrow gauge railways. The ROD operated their first line on a section of the Hazebrouck–Ypres line.
The ROD requisitioned many diverse locomotives from Britain's railway companies and leased several Belgian locomotives sent to France in 1914, but as the war dragged on adopted the Great Central Railway's Robinson Class 8K 2-8-0 as its standard freight locomotive to become the ROD 2-8-0. Some locomotives were also purchased from Baldwin in the United States. They also operated narrow-gauge engines (meter gauge or 600 millimetres (2.0 ft) gauge trains).
