Fast Line running all day

There is an ongoing points failure at Wembley Park. Northbound trains from Baker St can only access platform one at Wembley Park and then run via the fast line to Harrow.
In order to maintain a northbound service for Preston Road and Northwick Park a number of Baker St services are being reversed via Neasden Depot. Trains from the depot can be routed to Wembley Park platform two.
Train 441 is one of those that has been chosen to reverse via the depot.

This has been the case since Wednesday. Off-peak it’s the Watford - Baker Street (4tph) service that has been curtailed. At peak times it’s a mix of Watford/Uxbridge/Amersham - Baker Street services averaging a combined 6tph on the Northbound Local.

Yes, that’s correct. The broadcast advice for northbound passengers to stay on till Harrow and then return south reflects this heavy imbalance

Are there no signs explaining what is going on at stations South of Wembley?

Posters should now be up at all stations south of Harrow

In my own assessment it does cause some slight queueing outside of both Harrow and Wembley on the southbound. Although, I don’t think it is a huge impediment to the service. All in all, I’d say given the present woes and how much potential this issue had to nuke the service, the control room staff have done an admirable job keeping the service running fairly smoothly.

Although, I do wonder how long it will be before this points failure is likely to be fixed?

And now we are back to NB Amershams and Cheshams all fast north of Harrow because points across from the local north of Moor Park have failed again. Second time recently.

IIRC the points at Watford South Junction were reconfigured in circa 2008, so not old at all but at the same point not exactly young enough to be under manufacturer's warranty (please pardon the ropey analogy). I wonder if anyone on here knows the root cause of the failures on these points; are the present problems a repetition of others we've seen over the past few months?

I recall the first incident being being a "Cracked wing rail" - this is obviously the fault not the root cause.

Not sure if the timescale to repair (multiple days) was due to getting a replacement part or the remedial track work associated with the root cause (track alignment,  tamping, fettling, sleeper replacement etc.)

Sometimes, the dice just aren't on your side!

Seems like a late finishing of engineering works is causing severe delays across the line.

Anyone know what specific work was being done and why it means trains can't stop at Northwick park and a Preston road?

They've failed again. Non-stopping Preston Road & Northwick Park on the southbound.

Issue affecting southbound trains is still on going. All trains running semi fast and stopping at Wembley

Also how good is the communication at Preston road and Northwick Park? You can see people waiting on the southbound platform!

Another issue is that the service shows as "Good Service" which is not true at all. Tfl need to describe this as Minor delays and notify customers that southbound trains are not stopping at these stations.

Which point specifically has failed? Is it the one just south of Wembley where the local and fast lines join together?
