Was due to a damaged faraday cage on a signal (which protects those attending to a signal from the overhead wires).  It had come loose and was a danger to passing trains.

That I actually find to be more concerning. These cages are very low-tech constructions of steel frames and steel mesh. It should not be that hard to devise suitable fixings and to install them correctly so as to prevent them coming loose.

Imagine the consequences of a train hitting one Sad Apart from the potential danger at the time, imagine the disruption whilst the line is closed to examine each one.

A proper intercity train has a minimum of 8 coaches, gangwayed throughout, with first at one end, and a full sized buffet car between first and standard.
It has space for cycles, surfboards,luggage etc.
A 5 car DMU (Diesel Multiple Unit) is not a proper inter-city train. The 5+5 and 9 car DMUs are almost as bad.

Due to urgent repairs to the track between Ealing Broadway and London Paddington fewer trains are able to run on some lines.
Train services running to and from these stations may be delayed or revised. Disruption is expected until 10:30 30/09. ................what on Earth has happened?

Engineering train ran through a set of points during an possession of the line. Seemingly, this is becoming a regular occurrence

Also:
Due to a fault with the signalling system at Swindon trains have to run at reduced speed on some lines.
Impact: Train services running through this station may be cancelled, delayed by up to 60 minutes or revised. Disruption is expected until 11:00 30/09.

(Amongst other things this lead to the cancellation of 1L08 which left a bit of a gap in departures from Reading to Paddington during the morning peak)

I've lost track of the what work has been completed where but has all the signalling work been completed? There still seem to be signal failures but is this due to work to upgrade them or problems with the new system?

There's lots more signalling work to be done between Paddington and Hayes (Stockley Bridge) and at Maidenhead, for Crossrail.  The last stage is at Easter 2018 (or thereabouts Roll Eyes Tongue )

See this thread for details of the work at Christmas/New Year 2016: http://www.firstgreatwestern.info/coffeeshop/index.php?topic=17494.0

Modern electronic signalling is not quite as robust as the 'old hat' relay technology that existed before, and its design life is much shorter.  There is also the 'Bath Tub Effect' which most electronic systems suffer from whereby if its going to fail it has a higher chance when its new and then towards the end of its life.  Electronic systems also don't like being disturbed, which of course is occuring almost daily at present.

Another morning of joy on LTV (London [and] Thames Valley).........................Due to a fault with the signalling system between Slough and London Paddington fewer trains are able to run on some lines towards London Paddington.
Train services running to and from these stations may be delayed by up to 15 minutes or revised. Langley, Iver and West Drayton will not be served.

Apparently a fault at West Drayton. Up Main traffic diverted onto Up Relief.

Delays to services between Didcot Parkway and Oxford
Due to a speed restriction earlier today between Didcot Parkway and Oxford trains have to run at reduced speed on the line towards Oxford.
Train services running through these stations may be delayed by up to 40 minutes. Disruption is expected until 19:00 12/10.

Emergency track repairs just south of Oxford caused disruption for most of this afternoon, culminating in no northbound services - through or terminating at Oxford - for an hour between 1620 & 1720.

[Thursday am] - just realised 1545 Reading - Newcastle started from Oxford on platform 3. Realtime Trains suggests nothing coming from south of Oxford from 1545 to 1722

Emergency repairs took longer than expected.  Fortunately the High Speed Train (HST (High Speed Train (Inter City class 43 125 units))) to Moreton ran all the way as control wanted to terminate it at Charlbury.  After the cancellation of the previous train, sheer weight of passenger numbers forced a change of mind.

Not sure if a broken down train counts as infrastructure but anyway...

"Cancellations to services between Didcot Parkway and Oxford
Due to a broken down train between Didcot Parkway and Oxford the line towards Oxford is blocked.
Train services running through these stations may be cancelled or delayed by up to 60 minutes. Disruption is expected until 19:45 13/10."

Seems several Oxford bound trains currently being held at Reading.

Was a failed Class 70 on a Freightliner at Radley.  After a bit of coaxing from the driver it managed to limp into Hinksey Yard and out of harms way.
