.....Does the great western line have a track security problem?

The volume of graffiti, AKA^▸ ('also known as') criminal damage, along the railway between Paddington & Acton, indicates the answer to that question is a resounding 'Yes'.

Ah but Bob that graffiti is "art", and yet another benefit of our increasingly progressive, diverse society (....or something!)

What has happened?
-
There has been a points failure in the Southall area. A points failure is a fault with the movable pieces of track that enable trains to change tracks.
-
There is also a defect with the track in the West Drayton area which means trains are having to run at reduced speed on one of the four lines towards London Paddington.

And even more misery, must be because the weather got a bit warm today.

Due to a fault with the signalling system between Oxford and Didcot Parkway all lines will be blocked.
Impact:
Train services running through these stations will be cancelled or delayed. Disruption is expected until 20:00 08/04.
Customer Advice:
-
What has happened?
-
Some axle counters, part of the signalling system, have stopped working in the Oxford area. Axle counters tell the signalling system if a section of track has a train on it. If an axle counter stops working, trains need to stop at the affected signal so that the Driver can speak to the Signaller to confirm if the track ahead is clear.
-
What are we doing about it?
-
All lines are blocked for 30 minutes to allow Network Rail to access the site to resolve the issue.

Now pushed out to 1100

"The problem affects 2 of the four lines between London Paddington and Reading, so we are having to reduce the train service through the area to avoid congestion. Local stopping services between London Paddington and Newbury will only run between Reading and Newbury. Most longer distance intercity services will continue to run between London Paddington and Reading, but may be subject to delay.
We are working with Network Rail to be able to return to running our normal timetable as soon as possible".
