So it seems that 357 210, 357 205, and maybe 357 325 are in the GBR | Anglia livery now, if there are 8 of them in total, those having been the units under preparation.
Oh that does bring up a valid question, will GBR have 'celeb' trains (like that charity livery one you mentioned) or will they just stick to their standard livery? Would be a shame if there's no celeb liveries so I hope there are, but it will be interesting to see.
c2c is under GBR | Anglia now, and this new Gold Geese livery is more minimal than the previous all-over-golden-yellow-wrap one, which was replaced by the GBR | Anglia livery on 357 008 (which was originally said to be one of the last trains due to be re-painted, since it was carrying the special charity livery):
New, apparently 357 010:
Previous, launched on 1st September 2022, and done by Stewart Signs Rail (who also wrapped the GBR Class 701, and have also done work for Southeastern, TPE, CrossCountry, ScotRail, London Underground, Eurostar, Virgin Trains, Luas, and Edinburgh Trams over the last decade) - I’m a bit surprised that they didn’t clean the dirty body-work before just putting the vinyl on top of the dirt, though they did take the Trenitalia logo off first rather than covering it with the new vinyl, since you can see the clean shadow of where it used to be:
Given that LNER have been publicly-owned for quite a while now and have had quite a few special liveries, and I think Northern, which has also been publicly-owned for quite a while, has also had some I believe, perhaps that’ll continue under GBR.
c2c under public ownership also renewed their sponsorship of Southend United football club, which I was a bit surprised by, since the c2c brand is set to disappear.
