No, I don't think so. As part of the same programme, Eglinton Street was beefed up. This press release from Nov 2022 shows it, though it doesn't name Eglinton Street, and confusingly does name Ferguslie:
Yeah I believe the interventions were to install a cable from one of the Eglington supplies down to feed the route to a new TSC substation at Muirhouse South Jnc in order to feed the route to Barrhead/East Kilbride off of a separate supply to that which supplies the Glasgow Central area as far as Newton. Ferguslie is in many ways an upgrade to Eglinton Street as the west supply side feeds to Lochwinnoch and the eastern one feeds to Kinning Park TSC (and around to Bishopton). Previously Lochwinnoch/Bishopton/Paisley Canal to Kinning Park was fed by Eglinton Street via cables for each overhead line circuit going to the other side of Kinning Park neutral sections. I think putting in an actual TSC at Kinning Park was part of the upgrade as well.
So basically, Fergulsie took over feeding of the inner Ayrshire lines from Eglinton Street. Newton is currently the MPTSC between Gowkthrapple and Eglington Street so whatever it feeds will likely be taking something over from both of them.
But it'd be interesting to see what Newton ends up feeding as there are lot of lines snaking around there with Gowkthrapple and Greenhill's supply areas and alternate arrangements being quite complex. I remember seeing in a sectional appendix that there's recently-ish been a neutral section installed on the Kirkhill line at Newton West Jnc, this might have something to do with it. And another recently appeared at Haughead Jnc but confusingly placed to achieve nothing! Perhaps another will appear on WCML at Motherwell and make it all make sense.
Undoubtedly. (Edit: if that's the one named as Clyde's Mill on openinframap.)
My mistake sorry !
Of the six feeder stations named in #260, three are at new sites, and three (Currie, Newton and Portobello) are at sites where there was already a feeder station. I think at Portobello the new station replaces the old one? At the other two I'm not sure whether the new station replaces or supplements the old.
There aren't/weren't feeder stations at Currie and Newton although new switchgear/buildings are likely going in replacing the old. Both were midpoint TSCs. I think in the old layout, the lines east of Currie were fed by Portobello and west of there by Gowkthrapple via Carstairs TSC. Similarly, Newton is the midpoint between the other supply from Gowkthrapple and Eglinton Street and so probably dates from the 1970s.
At Portobello, I think new buildings/switchgear are being built, but the point of the work is to install a neutral section on the mainline at Portobello Jnc (and another on the Millerhill Loop at Monktonhall Jnc). I think the point of this is to allow the alternative supply at Portobello to independently feed the section Portobello Jnc to Longniddry, while the other feeds the route through Waverley to Haymarket and the Millerhill Loop + slight bit of borders railway. This probably has more to do with the ECML PSU than anything else.
Portobello FS, like most feeders, was originally installed with two supplies - but for whatever reason they didn't put in a neutral section so only one supply could be in use at one time feeding originally Longniddry to Currie (and then just to Haymarket once Currie FS was installed).
To my knowledge this is the current situation, hopefully this contextualises what a Newton feeder could do... (The red coming through Garnqueen and orange at Queen Street are from Greenhill FS)
