GWML electrification dates revealed

Sir Peter Hendy has revealed the completion dates of each element of the delayed Great Western Main Line electrification programme in an updated report today (22 January).

All elements of the programme will only start seeing electric trains running in CP6 (2019-2024), but the dates set for infrastructure authorisation are:

  • Maidenhead to Didcot: December 2017
  • Didcot to Wootton Bassett Junction: December 2018
  • Wootton Bassett Junction to Bristol Parkway: December 2018
  • Reading to Newbury: December 2018
  • Bristol Parkway to Cardiff: December 2018
  • Didcot to Oxford: June 2019
  • Wootton Bassett Junction to Bristol Temple Meads: February 2019-April 2020
  • Filton Bank: Early CP6

The update comes two months after his long-awaited review of all CP5 projects was published, under which no projects were cancelled, most would go ahead as planned, but many “unrealistic and undeliverable” milestones were pushed back into CP6.

Part of this portfolio was the Great Western electrification scheme, which had already suffered a series of setbacks due to poor productivity linked to buried cables, inefficient use of midweek access, permissions and design standards, and many other issues. The costs also swelled massively.

At the time of his November review, Sir Peter said work to update the programme was “being concluded as this report is completed”.

As already indicated then, the Network Rail chair reiterated in today’s report that electrification beyond Cardiff will be kicked to CP6. Works between Bristol Parkway to Cardiff, originally expected for 2017, will see infrastructure completed by December 2018 and the first electric trains introduced in CP6 (providing trains are completed in time).

All of these dates are also based on a series of assumptions, including that signalling renewals projects will be completed on time, as well as the remodelling of Bristol East Junction and Oxford.

Currently, Hitachi’s InterCity Express Programme remains on schedule to deliver the new Class 800/801 fleet on the GWML by 2017. Given that the electrification scheme is running late, the Class 800 bi-mode trains will not be able to use their electric capabilities. The Class 801 fleet will be entirely electric.

Also today, the Department for Transport has launched a consultation on Sir Peter’s re-plan report, set to run until 18 March. Subject to feedback, transport secretary Patrick McLoughlin MP is expected to accept the review’s reformed milestones.

No date for Heathrow Junction to Maidenhead? I know this comes under "Crossrail" and not "GW" but would be interesting to know when this is expected to be comissioned

By the time(if) its all done the trains will be wedged from day one,this mob couldnt run a bath!

A little disappointing that Bristol has been pushed so far back, and will now be delivered after Cardiff. With those dates, and the new dates for other re-profiled projects, there is also going to be quite an impact on the amount of new work that can be added in CP6 - even if NR does manage to lift it's productivity. I suspect that NR will loose control of major projects, with the capital budget cut along with the cuts anticipated with the funding changes that are also being discussed. We may not see NR get such a big wish-list from teh Government in future years.

May I ask what is happening to the Oxford - Bletchley line? It seems portacabins were on site at Verney Junction for work to begin, but they have now disappeared again.

The Hendy Plan update referred to in the article has dates for all NR projects and is available via the Network Rail website. For Oxford - Bletchley (part of EWR2) it shows the design work (called GRIP 4) to complete in December 2019. Construction will start after this. Last I heard the disused track to Bletchley is to be rebuilt with twin track. The portacabins were probably related to preliminary groundwork investigations to drill boreholes, test pits etc to collect information for track design.

I have to agree with Jakjaye above. The new oxymoron is clearly 'British efficiency and competence'! This whole farrago is utterly pathetic. How ON EARTH did we ever build the railways in the 19th century? (Answer probably: Fewer politicians meddling!)

David Kerr   12/02/2016 at 14:40

Why are there so many people only too ready to decry this project as it is really down to the economic downturn throughout the world which governs the monies that can be made available during this time of fiscal restraint!

Stalinisation of GWML! Thrilled about electrification until I saw the OLE marching towards Didcot. I found photos of ECML, WCML, HS1 & proposed HS2 and all have OLE looking streamlined, modern and with much less adverse visual impact. Why and how have we ended up with this ugly industrial grade OLE reminiscent of Stalin's 1930s rush to industrialise the Soviet Union? Talk about disfiguring the countryside! Is this the South's punishment for not bearing the brunt of the Industrial Revolution?

Paul Jones   24/08/2016 at 19:22

There will be no class 801 on the GWML all trains are going to be class 800 bio mode because of the Network Rail fiasco regarding electrification as for the class 387 emu for the thames valley they are going to be used between London Paddington and Hayes and Harlington so by the time they get down to Reading they are half way to be being ruined what a shambolic shambles

I used to work on Computer projects 25 years ago. They went in on time and on Budget. In those days we had no idea if we could do it to the Published Dateline as we were working on new Technology and Software. However Railway Electrification is a totally known quantity. Its been done many times before. Even the cost of the wire and steel is known to the nearest £1. All Projects need a little wiggle room of possibly 5 to 10%. But this scheme is hopelessly out. I have watched the pylons and wires go up from my home Station in Tilehurst and it does seem horrendously slow progress. All I can guess is that someone 'improved' the original Plans to get the Government to sign up for the scheme. I really can't believe that the Team that did the original design could be so hopelessly wrong.
