Chattenden and Upnor Railway. A late nineteenth and early twentieth century military narrow gauge railway, connecting Chattenden Barracks (Monument 1545088) and Chattenden Magazines (Monument 1481790) with the Royal Naval Ordnance Depot at Upnor (Monument 1543146) and Pontoon Hard, on the Medway. The line, also known as the Lodge Hill and Upnor Railway, was constructed by the Royal Engineers beginning in 1873, when it ran as far north as Chattenden Magazines. In about 1892 the railway was extended eastwards into the Lodge Hill enclosure. In the early years of the twentieth century, this extension formed the central spine of the Royal Naval Armament Depot (Monument 1077634), with internal spurs serving the magazines, stores and laboratory. In about 1905 the railway was connected, via a transfer point in the Lodge Hill Depot, to the Chattenden Naval Tramway (Monument 1545591) and thereby linked with the main line at Sharnal Street to the east. The railway was used during the Second World War, although traffic declined after the end of the war, and it closed in 1961. The road from Chattenden Magazines to Upnor (Lochat Road and Upchat Road) follows the course of the railway. The railway as it existed in the Second World War has been mapped from aerial photographs as part of the English Heritage: Hoo Peninsula Landscape Project.
