Puzzled by part of their customer advice -
Customer Advice
Elizabeth line are conveying passengers via any reasonable route until further notice. Arrangements have been made for Great Western Railway rail tickets to be accepted for these journeys.

Surely the Elizabeth Line uses the same signals/points, etc as GWR^▸ (Great Western Railway), so how come they are apparently running, but not GWR?

Elizabeth Line gets priority and/or points have been secured to enable Elizabeth Line trains to operate

Just checked National Rail, everything (all Elizabeth Line) between  0815-1000 from Taplow is cancelled.....if that's priority I feel sorry for those at the back of the queue.

GWR now advising disruption till midday.

That sounds more like a line blockage to allow for a fix to be implemented or testing of the signaling equipment to be carried out.

Disruption now expected "until the end of the day"

Dear......
 
We are writing to update you on the disruption to train services between Reading and London Paddington this morning, due to a fault with the signalling system. This impacted GWR^▸ (Great Western Railway) South Wales services, as well as Heathrow Express and Elizabeth Line services.
 
Network Rail teams are on site investigating but we wanted you to be aware that it now seems likely that the disruption will continue for the rest of the day and into this evening.
 
An amended timetable is now in place for GWR, Heathrow Express and the Elizabeth line services as follows:
 
Heathrow Express running every 30 minutes
GWR London Paddington to South Wales services running hourly
Elizabeth Line and GWR working together to run four local trains per hour - two to Heathrow and two to Reading
 
All other GWR services are scheduled to run but could be subject to last minute cancellations and delays.
 
We sincerely apologise for the disruption and we are encouraging everyone to to check before they travel – either on our website or through National Rail Enquiries.
 
Network Rail are working hard to rectify the fault and we will keep you updated.
 
Best Wishes
 
Heledd and Jane

Just spoken to someone stuck at Slough Station who's been advised that everything towards Reading is cancelled for the next 90 mins.

Clipping and scotching points to give access to the CrossRail depot.

Disruption now forecast until 1000 on 26 July, well over 24 hours since it began.

It sometimes feels the system is so fragile that a feather could knock it over.

Disruption now forecast until 1200.

1800 now.

It appears to be a proper head scratcher!  They are still suffering interference on both the datalinks. The system has two datalinks for system redundancy. If one goes down you can run still run on the one good datalink.

I would suggest it's probably time for the head scratching to be replaced by arse kicking!

NR^» (Network Rail - home page) have just posted on X (Twitter) that it's 6pm 'at the earliest' which doesn't fill one with much confidence that it will be resolved before the day is out.

No confidence whatsoever.....I'm wondering what the public/media reaction would be if a major motorway or airport was restricted in a similar way for what will most likely be 48 hours?

Looks like London to Didcot/Newbury services now starting/finishing at Reading........which just leaves customers with the challenge of getting to/from Reading.......

All a process of elimination. Every single equipment cabinet in the Paddington to Acton area needs to be examined and tested. You could strike lucky and the problem might be in the first cabinet you test, or worst case, the last one.

We all still have a good moan! 
Motorways with lane closures where you don’t see a single person working and those average speed cameras…….. or alrports when they’re hit by IT failures or air traffic control goes down.
