Editing Subterranean London (section)

==Utilities==
London, like most other major cities, established an extensive underground infrastructure for [[electricity distribution]], [[natural gas]] supply, [[water supply]] and [[telecommunications]].

Starting in 1861, Victorian engineers built miles of purpose-built subways large enough to walk through, and through which they could run gas, electricity, water and hydraulic power pipes. These works removed the inconvenience of having to repeatedly excavate highways to allow access to underground utilities.<ref>Antony Clayton (2000) ''Subterranean City'' {{ISBN|0-948667-69-9}}</ref>
