[[Southgate tube station|Southgate station]] is in a tunnel, with tunnel portals to the north and south. Due to the difference in terrain, [[Arnos Park Viaduct|a viaduct]] carries the tracks through [[Arnos Park]] to [[Arnos Grove tube station|Arnos Grove]].{{sfn|Horne|2007|pp=78–79}} The line then descends into twin tube tunnels, passing through [[Wood Green tube station|Wood Green]], [[Finsbury Park tube station|Finsbury Park]] and central London. The central area contains stations close to tourist attractions, such as the [[London Transport Museum]], [[Harrods]], [[Buckingham Palace]] and [[Piccadilly Circus]].<ref>{{cite web |url=https://media.timeout.com/images/105275094/image.jpg |title=Out and about on the Piccadilly line |publisher=[[Transport for London]] |access-date=4 October 2020 |url-status=live |archive-url=https://web.archive.org/web/20201004100724/https://media.timeout.com/images/105275094/image.jpg |archive-date=4 October 2020}}</ref><ref>{{google maps |url=https://www.google.com.my/maps/place/Leicester+Square+Station/@51.5482801,-0.329954,28158m/data=!3m1!1e3!4m5!3m4!1s0x487604cd91e8c0f7:0xde0fdd0b8f9a7fcb!8m2!3d51.511451!4d-0.1281439?hl=en |title=Piccadilly line |access-date=4 October 2020}}</ref> The {{convert|15.3|km|mi|2|abbr=on|order=flip}} tunnel ends east of [[Barons Court tube station|Barons Court]], where the line continues west, parallel to the [[District line]], to Acton Town.

The Heathrow branch remains at surface level until the eastern approach to [[Hounslow West tube station|Hounslow West station]], where it enters a [[Tunnel|cut-and-cover tunnel]].

Traversing terrain with cuttings and embankments, it continues to Uxbridge, sharing tracks with the [[Metropolitan line]] between [[Rayners Lane tube station|Rayners Lane]] and Uxbridge.{{sfn|Horne|2007|pp=43–44}} The distance between Cockfosters and Uxbridge is {{convert|31.6|mi|km|abbr=on}}.{{Sfn|Horne|2007|p=99}}
