New WTTs in December

Well the District is definitely getting a new WTT, and I believe the H&C/Circle is too; so you might as well say the whole SSR is getting a new WTT in December.

As for the 'tube' lines, pass.... ....

NEW WORKING TIMETABLES
Metropolitan Line
All week
The Chesham-Chalfont & Latimer shuttle service is withdrawn.
Chesham services are now provided by the diversion of 2 of the 4 Amersham-Baker Street fast trains per hour. In consequence, Amersham services are reduced to 2tph and one less train is required for service.
During early morning and late evening periods when fast Amersham services operate at 2 tph, the 2tph Chesham service is provided by the diversion of 2 of the 6 Watford-Baker Street slow services per hour. In consequence services between Moor Park and Watford are reduced to 10/20 minute intervals and Chesham services will call at all stations.
As a result of revisions to the Amersham/Chesham service, there are significant alterations to the start and finish of services.
Mondays to Fridays
The southbound schools semi-fast train will depart later from Amersham at 16.16.
Sundays
The last train to Chesham will depart from Baker Street 13 minutes later at 23.24.

Circle and Hammersmith & City Line

This timetable introduces revised stabling arrangements and minor retimings to early and late train services. Service patterns, running times and frequencies remain unaltered throughout all days.

The stabling of trains at Farringdon Sidings is re-introduced.

District Line
All Week
Lillie Bridge depot will be used as a stabling location for 3 ‘D’ stock and 5 ‘C’ stock units. Due to S7 Stock enabling works, no trains will stable at Triangle sidings and 3 less trains will stable in Ealing Common depot. Lillie Bridge will be a stabling location for both District and Circle and Hammersmith & City Lines ‘C’ stock units.
Monday to Fridays and Saturdays
As a consequence of the stabling changes the early morning service on the Wimbledon branch has been revised.
