Metropolitan Line

The Metropolitan Line is a line of the London Underground. In its present-day form, it functions much like an overground suburban commuter railway: Baker Street station is its terminus, and as it reaches the outer suburbs of London it progressively branches off into several directions.

The line's operation is quite complex: fast services skip stations and overtake slower services. During peak hours, some trains run beyond Baker Street, further into London along the tracks of the Circle Line through to Aldgate.

The line has a complex history, and has seen many changes to its layout. It began as part of the low-level network which is now split into the Metropolitan Line, the Hammersmith & City Line and the East London Line.

The Metropolitan line is the only London Underground line to operate fast services that miss out certain stations. The current off=peak service pattern is as follows

• 6tph Uxbridge - Aldgate (all stations)
• 6tph Watford - Baker Street (all stations)
• 4tph Amersham - Baker Street (all stations to Moor Park, then Harrow-on-the-Hill, Wembley Park and Finchley Road only)

(tph=trains per hour)

In the peak other services can run, including through trains to Aldgate from Watford/Amersham, semi-fasts to Watford/Uxbridge missing out Northwick Park and Preston Road and through trains to Chesham. There are also a few trains from Rickmansworth to Watford very early in the morning and vice versa late at night.
