From the longer Wikipedia article [1] The Royal Victoria Dock is the largest of three docks in the Royal Docks of east London, now part of the redeveloped Docklands. It was opened in 1855 on a previously uninhabited area of the Plaistow Marshes, it was the first of the Royal Docks and the first London dock to be designed specifically to accommodate large steam ships. It was also the first to use hydraulic power to operate its machinery and the first to be connected to the national railway network via the Eastern Counties and Thames Junction Railway section of what is now the North London Line.[1] It was initially known as "Victoria Dock"; the prefix "Royal" was granted in 1880.
