This is a list of tram systems in the United Kingdom, along with references to them in OSM.
|Blackpool tramway||Not mapped|
|Croydon Tramlink||Complete - but order of stops on route relations is incorrect (use relation pages or öpnvkarte.de to verify)|
|Edinburgh Trams||(Under construction)|
|Great Orme Tramway (Llandudno)|
|Manchester Metrolink||In the process of re-vamping routes to reflect current pattern. Order of stops in some relations needs minor amendment. Arguably the Rochdale & Bury lines (north of Victoria), Altrincham and East Didsbury lines (south of St Peter's Square) should be re-tagged as Light Rail. Eccles is definitely correct as tram - Ashton and Airport lines are debatable.|
|Nottingham Express Transit|
