IDK for sure, the latest scope of TPRU seems to be a secret.
But would seem silly not to include such a short section as a useful diversion route when both sides are electrified.

To me there are too many Priority 1 routes there.
Yes in an ideal world they'd all be done straight away, but that's not going to happen, and by making so many P1, it's not really highlighting the REALLY urgent ones to be done first.

I see that the analysis tables in the RIA report incorrectly give the service frequency on the Mid Cheshire line (Chester - Stockport) as only 0.5tph, when it is actually 1tph. This error no doubt contributed to the route being classed as Priority 3.
Wigan - Kirkby has been classed as Priority 1, despite having only 1tph. This appears to be based on an assumption that Kirkby services will continue to work through to Blackburn via Todmorden, which would not necessarily be the case in a future post-electrification timetable. The Kirkby branch might be well suited to battery trains.

I agree - a hierarchy/priority list would be far more useful
In decarbonisation terms that could be as simple as counting the number of train service KMs and ranking in order of most electrified.
It seems that most recent electrification programs have been driven by rolling stock renewals, which is kind of counter to having the stock flexibility that leasing provides, not to mention bi-modes.

Tables 4, 6 & 8 in the RIA report do give priority ranking lists for all the routes: 1 - 40 are Priority 1, 41 - 47 are Priority 2 and 48 - 69 are Priority 3 (Middlesbrough - Whitby being No.69).
The report explains how the ranking was determined:
I think this all means that the final priority ranking was down to the authors' subjective judgement!

But 40 schemes is far too high for "priority 1", when that's over half of all the schemes and 85% of the ones recommended for electrification!
40 in P1 and only 7 in P2 is an unhelpful way of splitting them.

Agreed. Carlisle to Newcastle Priority 1? That is extracting the urine!

Why is Electrification in England progressing much slower ?
Had a read of the new civil engineer blog this morning and in 2022 only 2.2km of track was electrified nationally, which is less than 1% of the expected amount which totals to about 448km annually. In Scotland electrification seems to be happening at a much more consistent rate with more miles...

Why Is New Overhead Electrification So Ugly?

12th January 2023, newly published by DfT a decarbonisation document, page 74
Not newly published. Right at the start it says crown copyright 2021, and has a foreword by "The Rt Hon Grant Shapps MP, Secretary of State for Transport" - which he hasn't been since October 2022.
It appears to be the document published on 14 July 2021.
Edit: it seems that the surrounding bit of the DfT website has been updated today for the reasons given here.

There may well be 38 per cent of UKR which is electrified but there are probably only about as many electric freight locomotives to use it. Ten 88s and probably about twenty class 90s with the balance taken up with a handful of class 92 freight workings.

Traction Overhead Line Electrification - Peter Dearman PWI Lecture 18 January 2023
The lecture begins at about 25:00 in the video, after some non-technical discussion.
I recommend this as a good, clear, down to earth introduction to the basics. Somewhat simplified, because aimed at track engineers, but very wide ranging. Covers grid supply points and phase balancing; track sectioning, booster transformers, neutral sections and section insulators; and the pantograph/OLE interface, including wire tension versus speed and how overlaps work.

Including somehow the fact that electrification of the branch to some places, say Windermere, would allow electric trains to run all the way to somewhere else, in this example Manchester (or beyond).

was any new 25kv OLE energised in 2022?
what is forecast for 2023 (probably not much if any) but plenty in 2024

The core section of Crossrail/Elizabeth Line opened in 2022.
Glasow-Barrhead is supposed to be completed by the end of 2023.
Colton to Church Fenton is already substantially complete but not due for energisation until 2024 due to tie-in works needed at Christmas/ new year.
Manchester to Stalybridge may be substantially completed this year but is not due for service until 2024 for reasons unclear.
Kettering to Market Harborough was I think due for completion this year but that may have changed following the start and integration of the works to extend to Syston.
2024 should see some completions in Scotland.

Yes for commercial service but was energised several years earlier maybe as early as 2018 and that was what i was interested to know.

PWI Part 2
The CILT represntative gave a well anchored presentation that suggested that it would be difficult to secure DFT/Teasury support funding apart from short infills at critical transition points such the life expiry of the 66's. The future would appear to be bi-modes/tri-modes.
