the E&G quarter past the hour trains seem to be formed of a 4-car 380 every 2 hours, not sure where this extra unit came from.

Still all of the xx:00 services are formed of 7-coach 380s. Some xx:15 services, possibly all, are formed of 4-coach 380s.

ETA - I’m also still puzzled at where this extra unit came from.

I see that NR are tweeting that they are checking the OHLE between Greenville and Polmont via Grahamston, which suggests that it is all installed, and about to be energised.

excellent news- but what rolling stock can we use until the 385s come?

Well, I'm surprised it hasn't been said on here earlier, but ScotRail are looking to get 10x 365s up as a stopgap.
for the E&G via Falkirk High, yes. But what electric stock to use on the Cumbernauld-Falkirk Grahamston enabled by this new stretch of OLE? Not enough 365s to go round.

I had assumed that the new service from Cumbernauld via Grahamston wouldn't be starting until December at the earliest?

Great news! This has to be an important thing to have before the E&G can go all electric as with this in place, there's a diversionary route from Polmont to Cowlairs/Eastfield in case of problems on the main line. With this in place, I think the only "diesel diversionary route" that isn't available to electrics is Winchburgh-Dalmeny/Dalmeny-Haymarket... which will presumably happen soon? Or will it wait until the wires go over The Bridge?

Or will it wait until the wires go over The Bridge?

The Dalmeny Chord project was originally included in EGIP but was removed when they decided to run 8-car trains at existing frequency rather than adding more 6-car trains. That will allow trains to leave the E&G at Winchburgh Junction, then over a new chord from Kirkliston down to the Fife Circle line before continuing into Edinburgh via the new Gateway station. Electrification between Haymarket and Winchburch Junction via the new chord would be part of it. This new line would allow some express services to switch over to the less congested Fife lines through Haymarket, and meaning no reversal at Dalmeny for diverted trains. The junctions onto the E&G and Fife lines would be grade-separated to make this line as useful as possible.

It's unknown whether they would decide to wire up to Dalmeny at the same time. On one hand, the sidings wouldn't have a role for diverted E&G trains, but having an electrified triangular route north of Edinburgh makes it easier to turn electric trains around (e.g. if a windscreen breaks).

Electrifying the South Sub would achieve that. Trains could leave Waverley Eastbound and use the South Sub to turn and head west. (Newcastle works like that with its two Tyne bridges, allowing trains to depart in either direction and so effects turning of a train.) The South Sub would allow electric trains leaving the Millerhill depot to be turned by being given a choice of approaching Waverley from the East or the West.

As it is the lack of wires on the Winchburgh - Dalmeny section has already caused headaches.. Just last Saturday a points failure at Haymarket West meant the Up E&G couldn’t run although the Up Fife line was fine, so diversions via Dalmeny were available but because of the increased E&G electric service only a couple of Dunblanes and one E&G were able to take advantage of the diversion. One E&G terminated and started back at Linlithgow and quite a few were cancelled out and back at origin. It’s already tricky to divert via Dalmeny at short notice because of limited traincrew route knowledge but having to manage a mixed diesel and electric service as well makes things harder still. You really have to be on the ball so as not to run anything off the wires!

Yes, but that involves conflicting with more services and having route knowledge over the South Sub. In Newcastle it's easy enough for a train to be turned around in service since the loop is so small. Having the triangle would make it almost feasible to do in-service turns for trains via Linlithgow.

I think it'll just depend on how much it costs to wire up to and including those sidings, and how much benefit there would be. There would need to be overrun wires on both the lines heading to Dalmeny. If there are no major civil engineering obstacles in the way, the extra cost might be fairly minimal.

If/when the Almond chord is built, it would be ludicrous not to extend the wires to Dalmeny.

My crayonista vision is that longer-distance tickets to Edinburgh would include a plusbus/plustram ticket automatically, including the airport, and that semifast trains would run through to Gateway, and then turn round in the Dalmeny sidings.

I doubt LDHS services would do that, but there would be some value in electrifying them for peak Dunbar/Berwick services. At the moment there are some trains which run through to Haymarket, but that involves a shunt on the Fife lines to turn back. With the use of the Dalmeny loops trains could run through and call at Haymarket, South Gyle and Edinburgh Park before going off and waiting for a clear return path. Otherwise the only way of running past Haymarket is to go all the way onto the E&G via either route. That might be okay if you want to join up EMU services across Edinburgh, but having the turnback gives you most of the connectivity with less chance of delays propagating across the network.

There’s a Tweedbank-Edinburgh service that runs through to South Gyle in the morning peak, and obviously some go right through to Glenrothes. I’d be interested to know passenger numbers for Border line stations-South Gyle. Could possibly introduce a North Berwick/Dunbar peak service right through to South Gyle.

Having been on one of those services on Friday, it was reasonably loaded after Edinburgh but emptied out at Haymarket & South Gyle.

Before retiring last year I was an occasional morning Edinburgh to South Gyle user and there were quite a few getting off there. The train terminated there though.
