UPDATE FROM TFL: From Tuesday 3rd May the normal weekday timetable will resume. There are still a few trains to be repaired, therefore some cancellations will still occur during the day. We expect a full resumption of the weekday timetable from Monday 9th May.
Unfortunately, issues have been discovered in the wheelsets of the S8 stock which run on the Met Line and as a result, they will all have to be taken out of service and inspected, which will result in a shortage of operational trains. That being the case, an emergency timetable will be operating wef Monday 11th April.
In essence, it means that southbound Chesham trains will leave at 10 minutes and 40 minutes past the hour and southbound Amersham trains on the hour and half-hour and will terminate at Baker Street.
