The Chattenden and Upnor Railway (also known as the Lodge Hill and Upnor Railway) was a narrow gauge railway serving the military barracks and depot at Upnor, Kent and associated munitions and training depots. It was preceded in the early 1870s by a temporary standard-gauge railway. The 2 ft 6 in (762 mm) narrow gauge was built in 1885, and continued in use until the end of 1961.
