William Huskisson MP (Member of Parliament) was the first person to be killed by a train while crossing the tracks, in 1830.  Many more have died in the same way since then.  Don't take a chance: stop, look, listen.

On my first trip into London today (THA-PAD» (Paddington (London) - next trains)) since the Christmas break and noticed quite a few of those circular piles in evidence sticking out of the ground trackside between Reading and Theale, and also a few between Theale and Aldermaston. The work is spreading!

From GetReading

Quote

Network Rail had admitted to a Reading MP (Member of Parliament) that replacing decades-old infrastructure during the electrification process could cause more cancellations and delays.

Reading East MP Rob Wilson has published the letter from Patrick Hallgate, western route managing director at Network Rail which acknowledged problems suffered by rail commuters over the past few months.

Mr Hallgate, writing just before Christmas, does not rule out further problems.

He was responding to a letter from Mr Wilson concerning delays and cancellations around Reading Station in late 2014.

He referred to investment replacing signalling equipment - some 60-years-old - East of Reading and in Slough.

He said; "The most disappointing aspect of the investment this year has been the significant impact that the works have caused on the day-to-day operation.

"We have instigated a piece of work due to report back early January which examined what additional mitigations we can put in place immediately which would reduce the likelihood of these of these occurrences."

He referred to piling work in October which led to Mr Wilson's original letter.

He said: "Whilst we are content that this will reduce the likelihood that there will be further recurrence, we must also be realistic.

"There are 15,000 piles to be placed as part of the electrification programme and just over 1,200 of them are now completed.

"With a number of cables buried for decades, it is likely that at some stage we will cause another problem."

He went on: "The key is to ensure that the 'high risk' cables are treated as such, with additional mitigations applied to them and work carried out at a less disruptive point in time where possible."

He added: "Whilst our general asset performance for the inner Thames Valley has improved over the past six months, I appreciate this is scant consolation to those caught up in disruption. "We have been having less incidents, but they are causing increasing amounts of delay."

Commenting on his letter Mr Wilson said: ^m pleased that Network Rail acknowledges the impact that problems on the rail network have had on passengers and that action will be taken to lessen the impact of future disruption.

"I welcome the news that the re-signalling to the east of Reading will be completed by Easter, as well as pledge of additional mitigation, especially in high risk areas.

^It^s clear that the transformational changes taking place require massive upgrades to the current network ^ indeed this Government is overseeing the biggest investment in the railways since the Victorian era.

^It is therefore inevitable that errors will occur from time-to-time, however limiting the frequency of disruption and dealing with delays and cancellations effectively is absolutely imperative.

"During the latter months of 2014 the performance at times was completely unacceptable and this must be rectified.

^Apologies and acknowledgements of error cannot absolve poor performance; what commuters expect is an efficient, punctual service and that is something I will continue to push for.

"I hope that this will indeed be the case from now on and I will continue to liaise with Network Rail and First Great Western, feeding back to my constituents at every possible opportunity.^

This would give a new slant to electrification being "green". There are a number of straight stemmed trees strong enough for catenary support, with stiffening. It would certainly be much cheaper just to plant trackside seeds every 50m; by the time DfT» (Department for Transport - about) got round to approving the wiring, they would be to full height.

Is the new office and sidings on the north side of the track just East of Swindon station to do with electrification?

Yes, it's where the HOOP factory train lives:

Just saw the HOPS (formerly HOOP) unit as we passed through Swindon from PAD» (Paddington (London) - next trains). This is the first time in quite a few months that I have done the journey, and so much has changed!

...hmmm not so sure about that.  I thought the electrification 'factory' was on the South side of the line near Highworth Junction.

Ah! You could be right about the South side, thinking about it. I have definitely seen electrification equipment between Bruce Street bridges and the Highworth junction on the South and that's probably what I was thinking of.

Bit of news from an engineering update I've seen:

The HOPS train should start its first wiring runs in February, and the IEP (Intercity Express Program / Project.) test section, between Didcot and Tilehurst, is on time to be energised in August 2015.  That follows the IEP's arrival from Japan in March, testing at Old Darby from April and ECML (East Coast Main Line) testing between April and October, so we might just see an IEP doing testing runs on the GWML (Great Western Main Line) before the end of the year.

Test runs at quiet times between Paddington and Airport Junction before then perhaps?

Errrrrrrrrrrrrrrrrrr when?

The Didcot / Tilehurst will enable daytime test runs, the tests are I believe for ATP (Automatic Train Protection) also to allow some test on the OLE (Overhead Line Equipment, more often "OHLE") fault protection system (which for GWEP (Great Western Electrification Program) is new a novel IEC 61850 based system ie it ain't been used anywhere else in the world for rail OLE traction complete with Goose messages  Shocked )

From my informed sources  Cool the wires will be up however there is likely to be some "fine tuning" once the test runs are complete.
