===A separate identity===
The Hammersmith & City line was shown on the [[tube map]] as part of the [[Metropolitan line]] until 1990, when it became separated, and the Metropolitan line became the route from Aldgate to Baker Street and northwards through "[[Metro-land]]" to Uxbridge, [[Watford tube station|Watford]] and [[Amersham station|Amersham]].{{sfn|Rose|2007}}<ref name="T90">{{cite web|title=London Underground map 1990|url=http://www.clarksbury.com/cdl/maps/tube90.jpg|work=The London Tube map archive|access-date=21 November 2012}}</ref> In 2003, the infrastructure of the Hammersmith & City line was partly privatised in a [[public–private partnership]], managed by the [[Metronet (British infrastructure company)|Metronet]] consortium.
