What does that mean for XC services though?
Construction commencing before the end of 2021. The section from Tweedbank to Bowshank Tunnel wired initially.Borders line is slowly getting worked out
I also find BEMU 2030 & EMU 2035 in that map baffling.If I’m understanding this screenshot from the video correctly the pink sections will be wired by 2030 is that correct?

I also find BEMU 2030 & EMU 2035 in that map baffling.
In the south west, I can totally see the ambition to wire filly to Kilmarnock and then operate BEMU to Dumfries. But why on earth would Dumfries be wired fully to Sanquar but not to Gretna, as the latter has more than double the traffic and I can't think of any major structures. And then connect the discontinuously electrified GSW mainline at Mauchline with full wiring to Ayr?? No passenger service and, apart from when the WCML is shut, not enough weekly freight movements to warrant the use of a second hand to count them.
Isn't it the other way around? The EMU by 2035 sections would be wired after the BEMU by 2030 ones. So, a Glasgow-Dumfries service in 2030 would be a BEMU using wires to Barrhead, then battery power to Kilmarnock, wires to Sanquhar, and then battery to Kilmarnock.
BEMUs require a quite different pattern of electrified sections. A traditional electrification scheme can only be done incrementally - e.g. you'd go to Barrhead, then Kilmarnock, then Dumfries, then Carlisle. At each stage, EMUs would stretch further and further. With a BEMU, you're optimising for the battery capabilities alongside the easiest sections to wire up. You want the batteries to be fully charged at the end of the wires, and then you'd need to start them again before the battery would run out. The Kilmarnock-Sanquhar wiring is long enough for a BEMU depleted after reaching Kilmarnock to be sufficiently charged to reach Dumfries.
Leaving the Barrhead-Kilmarnock section alone is a good demonstration of what BEMUs can do. It means you don't have to worry too much about redoubling that line ahead of electrification. We will probably see similar wiring gaps wherever there's something that might pause a straightforward wiring team, like the need to remodel Perth station.
No as a general rule there are of course always exception. Scotland goal is to electrify most so no point. If you are going to the expense of extension leads you might as well wire.With regard to the discussions above about feeders in little islands, would there be a case for extension leads a-la Stalybridge, or do the "gaps" and obstacles exceed distances that can be handled by something like that?
What does that mean for XC services though?
It's important to note that in England, while we may see something similar, there hasn't been a commitment to do the middle bits as well. In Scotland, the government wants wires everywhere possible because it's cheaper to run an EMU, and so has committed to coming back for the difficult bits by 2035.
I guess the advantage of that approach is that, if for some reason it turns out to be impossible (or there's no money) to do the difficult bits by 2035, then you can leave them and you've still achieved the primary aim of, no running on diesel. I wonder if set against that there's a minor cost disadvantage that you have to commission BEMU trains that can run for 30-35 miles on batteries, only to then presumably rip the batteries out a few years later once you have electrified the entire line?

Barrhead to Kilmarnock needs doubling before wires
I'm not sure why Barrhead/Kilmarnock needs (more) redoubling for electrification ? The current infrastructure is perfectly adequate (as long as Lugton SB is switched in !) for a half-hourly service, would electric trains generate a need for a more intensive service ?
This isn't really ScotRail's problem. It's more a problem for GBR when that spools up.
If the Scottish government turns around and says "no more diesel trains north of the border beyond 2030" then the UK government has to pull its finger out and decide on bimodes or cutting services at Newcastle.
Yes, I have advocated heavily for XC to continue running to Edinburgh, but 2030 is high time to have started thinking about switching to bimodes anyway. It would be a heavy loss of connectivity to cut services, but I can kind of see ScotGov's point. What the UK government does or doesn't do is outside its remit, instead it has to concentrate on how to better the situation north of the border.
Worst case scenario, I could forsee a derogation for five years or so, until 2035, to run as far as Edinburgh, but nobody wants voyagers trundling around for much longer than that anyway. Sooner or later replacements will be needed, and bimodes are the best solution as long as the UK government dithers on electrification. I suspect we'll see a battle of wills between the two, and I suspect this argument may come down in favour of the Scottish position.
I can see them pushing for 100% bio-diesal in all rail refuelling points in Scotland in the next 5 years.There will still be petrol & diesel engines in use, it's only new ones banned from 2030, & for private vehicles & small vans.
I also can't see ScotGov barring them until all of ScotRail is operating non-ICE services.

The plan is 2tph semi-fast and 1tph fast as far as Kilmarnock, with the fast continuing as far as Carlisle and one of the semi-fasts a distance down the line (Dumfries has been suggested but I expect it will be new cumnock as after that it gets a bit sparse)

Thats fine provided the bio diesel gives similar fuel range to now otherwise there might be problems.
I don't think Scot Gov has any say in what the long distance operators use, in fact I think that domestically being able to point that 'they' have achieved 'decarb' while the operators managed by DFT/Westminster are still using diesels would play well to their supporters.
When the WCML was closed in 2015 due to the storm damage at Lamington Viaduct, Virgin Trains ran a shuttle service between Carlisle and Glasgow Central via Kilmarnock. In order to path these services, Scotrail had to cancel their stopping services between Kilmarnock and Barrhead. Some of the Virgin Trains services called additionally at Kilmarnock. TPE were unable to run their services to Glasgow.Interesting, thanks for the info, however personally I am not sure the traffic to Kilmarnock, let alone from there to Dumfries, can justify such a level of service. Obviously passenger numbers are well down now (but who knows when or if they will recover ?), but this morning, at Barrhead at around 0920, a 2-car 156 on a Kilmarnock-Glasgow service was more than adequate, while the 4-car 156 I caught going south had perhaps 4 or 5 passengers per coach. Still, nothing wrong with ambition !

A graduate in geography and urban design, John Yellowlees spent seventeen years in the Departments of the Environment and Transport mostly in London before joining the railways in Scotland where he latterly led ScotRail's ‘Adopt a Station’ programme before retiring last year into an honorary role. A link between the two parts of his career was provided by Michael Portillo for whom he worked thirty years ago on transport for London Docklands, then in recent years provided support on filming the Scottish legs of Great British Railway Journeys.
Going Round in Circles
John will look at history of the Caledonian Railway and the development of Glasgow's South Side.
When the WCML was closed in 2015 due to the storm damage at Lamington Viaduct, Virgin Trains ran a shuttle service between Carlisle and Glasgow Central via Kilmarnock. In order to path these services, Scotrail had to cancel their stopping services between Kilmarnock and Barrhead. Some of the Virgin Trains services called additionally at Kilmarnock. TPE were unable to run their services to Glasgow.
John told us that Network Rail anticipate a long blockade of the WCML when they upgrade it for HS2 services and this is why they were (at that time) considering upgrade and electrification of the G&SW / Glasgow Barrhead and Kilmarnock Railway for diversion of freight and passenger services.

Working in Glasgow Control during the Lamington closure I am only too well aware of the pathing difficulties via the GSW ! To clarify, some Scotrail services were withdrawn (a suggestion I made very early on) to provide paths for diverted trains, but not all; A service was still provided, albeit reduced.
That's interesting, although to be of any use the entire length of the GSW would have to be electrified throughout, which does not appear to be the current proposal. Wiring Mauchline-Newton Jc might also be necessary to accommodate freight.
Interesting. Without wanting to go too far off-topic, what kind of upgrade are they anticipating? I was under the impression that the plan was for HS2 trains to run on the existing WCML North of Preston, with the lower max speed (due to HS2 trains being non-tilting) compensated for by their quicker acceleration compared to Pendolinos giving similar journey times to today, and therefore no extensive upgrade required. Is that not correct?

The proposed upgrade of the WCML for HS2 would be to ease the radius of curves through Annandale. Major civil engineering.

Getting my long since retired crayons out, I always fancied a tunnel between Elvanfoot and Abington, under Mid Hill. Would enable a 2 minute saving. Although it would cost quite a few quid!
