Installation Of OLE Begins In The Valleys
The title of this post, is the same as that of a short article in the September 2021 Edition of Modern Railways.
This is the first paragraph.
Construction of Core Valley Lines (CVL) overhead electrification equipment commenced on 26 July, when the first piles for masts were installed on the Aberdare branch.
The article appears has several small stories buried in the text.
Was This Good Project Management?
This is a paragraph.
The work, between Penrhiwceiber and Mountain Ash took place a year later than Transport for Wales had aimed for prior to the Covid-19 pandemic. However, TfW does not expect significant delays to completion, because the CVL transformation has been rescheduled and revised.
It certainly sounds like it to me that good Project Management has brought the electrification back on track.
I have seen this happen many times over past decades.
Yesterday, at Whitechapel station, I asked one of Crossrail’s Senior Managers, who in the past had used Artemis, if good project management was bringing Crossrail under control. He gave a knowing smile and said that there’s still a lot to do with the trains and gave me the official First Half Of Next Year answer.
But I do wonder, if we’ll get a surprise!
Battery Power To The Rescue
This is a paragraph.
Less overhead line electrification will be needed than was expected when the plans were announced in 2018. Improvements in battery technology enable the battery/electric dock to run further without OLE than had been assumed.
There must be an optimal point, where the extra expense of battery/electric trains are paid for by the savings and disruption of not installing overhead line equipment.
Using The Pandemic To Advantage
This is a paragraph.
TfW also accelerated preparatory works between Radyr and Pontypridd with a three-week blockade last winter taking advantage of low passenger numbers during the second Covid-19 lockdown.
It sounds like another case of good Project Management.
Dealing With A Level Crossing
This is a paragraph.
A crossing on the Rhondda Line will be permanently closed as a result of TfW purchasing the only building accessed by it! Deputy Climate Change Minister Lee Waters said it was more cost-effective for TfW to acquire the former army barracks at Pentre than spend an estimated £450,000 to bring the nearby crossing up to the requisite safety standards.
This Google Map shows the site.
It strikes me, that Transport for Wales will have to be very innovative to find a sensible use for a site hemmed in by the railway on one side and the River Rhondda on the other.
Conclusion
As we do more electrification in the UK, hopefully we’ll get better at it.

In the Valleys costs can be cut by having OHL installed only up the hills, but none down the hills or on the flat, using battery if necessary.

I proposed that in a post in June 2018
I would have thought that with regenerative braking to batteries was obvious engineering.
