Editing Metropolitan line (section)

==Services==
The Metropolitan line is the only London Underground line to operate non-stop services through some of its stations, although since 11 December 2011 these only run on weekdays during peak times (southbound in the morning peak, northbound in the evening peak).<ref name="autogenerated1">{{Cite web |url=http://content.tfl.gov.uk/wtt-340-metropolitan-21-may-2017-.pdf |title=Working timetable 340 - Metropolitan line. |access-date=5 May 2018 |archive-url=https://web.archive.org/web/20170521010101/http://content.tfl.gov.uk/wtt%2D340%2Dmetropolitan%2D21%2Dmay%2D2017%2D.pdf |archive-date=21 May 2017 |url-status=dead }}</ref> Depending on the stopping pattern, services are advertised as either ''all-stations'', ''semi-fast'' or ''fast'' on platform information boards and on-train announcements. The stopping pattern of each type of service is as follows:
*''All-stations'' services call at all stations en route<ref name="autogenerated1" />
*''Semi-fast'' services run non-stop between {{lus|Wembley Park}} and {{stn|Harrow-on-the-Hill}}, and call at all other stations en route<ref name="autogenerated1" />
*''Fast'' services run non-stop between Wembley Park and Harrow-on-the-Hill and between Harrow-on-the-Hill and {{lus|Moor Park}}<ref name="autogenerated1" />
*In the southbound direction, ''fast'' and ''semi-fast'' trains do not usually call at Wembley Park, and instead run non-stop from Harrow-on-the-Hill to {{lus|Finchley Road}}<ref name="autogenerated1" />

Owing to the track layout, ''fast'' services can only run to/from {{stn|Amersham}} or {{lus|Chesham}}. The {{lus|Uxbridge}} branch diverges from the rest of the line before the "fast" section, while the {{lus|Watford}} branch is not directly connected with the fast line at Moor Park.<ref>[http://cartometro.com/cartes/metro-london/ Detailed London transport map] - Carto Metro</ref>

No Metropolitan line trains call at any intermediate stations between Finchley Road and Wembley Park. These stations are served by the [[Jubilee line]] which runs parallel to the Metropolitan line along this section.<ref name="autogenerated1" />

===Frequency===
{{Update|section|date=January 2025}}
During the off-peak the service pattern on the line, in trains per hour (tph), is as follows:<ref name="autogenerated1" />
*8{{nbsp}}tph {{lus|Aldgate}} - {{lus|Uxbridge}} (all stations);
*4{{nbsp}}tph {{lus|Baker Street}} - {{lus|Watford}} (all stations);
*2{{nbsp}}tph {{lus|Aldgate}} - {{stn|Amersham}} (all stations);
*2{{nbsp}}tph {{lus|Aldgate}} - {{lus|Chesham}} (all stations).

These services combine to give a total frequency of 16{{nbsp}}tph between Baker Street and Harrow-on-the-Hill. Of these, 12{{nbsp}}tph run between Aldgate and Baker Street which, together with the 6{{nbsp}}tph frequencies on both the [[Circle line (London Underground)|Circle]] and [[Hammersmith & City line|Hammersmith & City]] lines,<ref>{{Cite web |url=http://content.tfl.gov.uk/wtt-35-circle-and-hammersmith-and-city-21-may-2017.pdf |title=Working timetable 35 - Circle and Hammersmith & City lines |access-date=27 March 2020 |archive-date=15 June 2021 |archive-url=https://web.archive.org/web/20210615053902/https://content.tfl.gov.uk/wtt-35-circle-and-hammersmith-and-city-21-may-2017.pdf |url-status=dead }}</ref> gives a total of 24 trains every hour on the central-London section between Liverpool Street and Baker Street.

In the morning peak, the southbound service pattern is strengthened to the following:<ref name="autogenerated1" />
*4{{nbsp}}tph {{lus|Uxbridge}} - {{lus|Baker Street}} (all stations);
*6{{nbsp}}tph {{lus|Uxbridge}} - {{lus|Aldgate}} (4 all stations, 2 semi-fast);
*6{{nbsp}}tph {{lus|Watford}} - {{lus|Baker Street}} (3 all stations, 3 semi-fast);
*2{{nbsp}}tph {{lus|Watford}} - {{lus|Aldgate}} (1 all stations, 1 semi-fast);
*4{{nbsp}}tph {{stn|Amersham}} - {{lus|Aldgate}} (2 semi-fast, 2 fast)
*2{{nbsp}}tph {{lus|Chesham}} - {{lus|Aldgate}} (fast).

The northbound frequencies in the morning peak are similar on each route, except most trains run as ''all-stations'' services.

Similarly, in the evening peak, the northbound service pattern is strengthened to the following:<ref name="autogenerated1" />
*3{{nbsp}}tph {{lus|Baker Street}} - {{lus|Uxbridge}} (all stations);
*7{{nbsp}}tph {{lus|Aldgate}} - {{lus|Uxbridge}} (all stations);
*4{{nbsp}}tph {{lus|Baker Street}} - {{lus|Watford}} (2 all stations, 2 semi-fast)
*4{{nbsp}}tph {{lus|Aldgate}} - {{lus|Watford}} (semi-fast);
*2{{nbsp}}tph {{lus|Baker Street}} - {{stn|Amersham}} (semi-fast);
*2{{nbsp}}tph {{lus|Aldgate}} - {{stn|Amersham}} (fast);
*2{{nbsp}}tph {{lus|Aldgate}} - {{stn|Chesham}} (fast).

The southbound frequencies in the evening peak are similar on each route, except all trains run as ''all-stations'' services.
