Most regrettable IMHO, though I cant see what else they could have done.

Network rail, who are, in all but name, a part of the government have proved themselves incapable of managing this project.
Costs have ballooned and the work has been endlessly delayed.

Politically, railway electrification has gone from a good thing that will win votes, to being a spectacular vote loser.

The routes planned to be electrified are lined with affluent NIMBYs, who may have welcomed clean and not so loud electric trains to begin with, but have now decided that the structures look so bad as to outweigh the advantages. THE NIMBYS HAVE WON

The work done so far has had a disastrous effect on punctuality in the Thames valley area, also a vote loser.

And the new trains for the West have gradually morphed from "high specification, inter city trains" to DMUs with underfloor engines and of course no buffet.

Crossrail 2: Support by government 'outrageous' after northern snub:
http://www.bbc.co.uk/news/uk-england-40708531

Government support for a new London rail line after scrapping projects in Wales and the north of England has been described as "frankly outrageous".
Greater Manchester mayor Andy Burnham said there would be "widespread anger" at the decision to back the railway line, which will run through London. Liverpool City Region's mayor said there needed to be "balanced spending". The government said it was spending billions on infrastructure elsewhere. On Friday it was announced that the rail link between Manchester and Newcastle may not be fully electrified, despite promises from the previous government.

'Northern commuters furious'
Greater Manchester mayor Andy Burnham said: "We can't wait forever, we need improvements now, that's why the electrification is important, and it's also why we need more capacity at Manchester Piccadilly. "People travelling [to Manchester] across the northern cities who will have a long commute home, I think, will be furious... that the government has cut back on rail investment in the north on the day that it's green light to Crossrail 2. "They're not governing for the whole country." Crossrail 2, a north-east to south-west railway, which would tunnel beneath central London, could be running by 2033. It is estimated the scheme will cost about £30bn at 2014 prices and construction could start in the early 2020s. It would link Hertfordshire and Surrey, passing through Tottenham Hale, Euston-St Pancras, Tottenham Court Road, Victoria and Clapham Junction. Announcing the decision to back Crossrail 2, the Department for Transport (DfT) said Transport Secretary Chris Grayling and Mayor of London Sadiq Khan had agreed there was "no doubt London needs new infrastructure to support its growth and ensure it continues as the UK's economic powerhouse". Mr Grayling said: "I am a supporter of Crossrail 2, but given its price tag we have to ensure that we get this right. "The mayor and I have agreed to work together on it over the coming months to develop plans that are as strong as possible, so that the public gets an affordable scheme that is fair to the UK taxpayer."

'Sub-standard rail services'
Last week, the government was criticised for scrapping the planned electrification of railway lines in parts of England and Wales. At the time, Mr Grayling said the government would instead introduce faster trains with more seats and better on-board facilities. On Monday Mr Burnham tweeted: "On Friday, Tories say they can't afford rail schemes in the North. "On Monday, they find billions more for London. Are these 2 things linked?" He said: "People here have had to put up with sub-standard rail services for decades and will simply not accept that spending billions more on London is the country's highest priority for transport investment.". He added that the fact the announcement had been made after Parliament had broken up for the summer was "denying any real scrutiny" of the decision.

'Future prosperity'
Liverpool City Region Mayor Steve Rotheram said that while he did not "begrudge" the investment in London and the South East, there needed to be balanced spending to "support growth in the North as well". London Mayor Sadiq Khan said: "Crossrail 2 is essential for the future prosperity of London and the South East, so I'm pleased that the transport secretary and I have reached an agreement to take this vital project forward." A DfT spokesman said that while it had agreed to work further with Transport for London on Crossrail 2, it said London needed to pay half of the upfront construction costs and that the government had not committed any public funding yet. The spokesman added that the government was spending £57bn on HS2, £1bn to improve rail infrastructure in the north of England and £800m on new road schemes.

Another setback to rail electrification is appearing.
All new schemes use 25Kv AC, sufficient clearance must of course be allowed between this voltage and nearby structures.

These clearances seem to be steadily increasing, due to EU regulation. I am not aware of any general reduction in the insulating qualities of air, so why do we now need much bigger clearances than those that have sufficed for decades on already electrified routes.

ONE of the reasons for ballooning costs is the need to raise bridges over railway lines, including bridges that would have been compliant until recently.

Increased clearances between the overhead and persons standing on the platform are also required, despite existing clearances having a good safety record.
Fatal accidents have occurred, but not many. And most of those involved stupidity.

No problem then, we won’t be in the EU for much longer.

I seem to remember 30kV per inch for air breakdown. Although that is dry air, peak voltage, no condensation on metal supports etc.
