Metropolitan train line difficulties

The Metropolitan service has issued an apology, giving the following explanation:

“Unfortunately we’ve got a couple of big issues going on:-

We do have some train operator resourcing issues, we’ve had higher than expected attrition however we do have new train operators coming in so this should resolve soon.

We are also having to train all our operators on the next section of the 4LM signalling upgrade (SMA9) so this is not helping with our availability. We’ve reviewed the training programme to lessen the burden on coverage. Next week there will be less courses running and so should help with our duty coverage.

In addition there are some issues with the track condition so there are currently speed restrictions in the Wembley area. The whole area will be rerailed over the coming weeks which will mean the speed restriction can be lifted.”

Met Line temporary closure information 19‑22 February

A message from FOMLUC (Federation of Metropolitan Line Users’ Committees).

This is to remind you of the Met line closure over 19-22 February during part of the half-term week.

This closure means there will be no service between Harrow-on-the-Hill, Amersham, Chesham and Watford. Chiltern Railways services between Marylebone and Aylesbury Vale Parkway (via Amersham) will also be closed. Rail replacement buses will run to affected stations between Harrow-on-the-Hill, Amersham, Chesham and Watford.

This closure will allow us to test our new signalling system, part of the Four Lines Modernisation project.
