Gauge: 1ft 6in (460 mm), 2ft 6in (760mm)
The first line between Chattenden and Upnor was standard gauge and was constructed in about 1870 to serve an Army camp at Chattenden. In 1872 its trackbed was used to lay a 1ft 6 in gauge railway for use as a training line by the Royal Engineers based in the Barracks. Between 1875 and 1878 magazines were built at Chattenden by convict labour brought in from Chatham by the railway.
In 1891 the Admiralty took over from the Army full responsibility for supplying armaments to the Fleet and consequently Upnor Depot, theTudor fort, and its associated depot on the shore of the River Medway were transferred from the War Office to the Admiralty, followed by Chattenden Barracks and the railway in 1904. By that time an extensive new armaments depot had been built at Lodge Hill and the railway line had been re-gauged to 2ft 6in. The Admiralty took over the railway system in 1906 and the RE Railway School moved to Longmoor in Hampshire.
The line was officially titled in 1906 “The Lodge Hill and Upnor Railway” and it was used for the carriage of munitions discharged from warships entering Chatham Naval Dockyard for repair or refit. The railway took the ammunition inland from Upnor Pier to magazines at Lodge Hill. There was also a timetabled service for naval staff taking in Chattenden Barracks, the railway workshops, engine sheds and stores. The line closed completely in 1961.
A wide range of rolling stock types was hauled by fourteen different steam locomotives and later diesels. Battery electric locomotives were used for shunting ammunition wagons on the sidings.
