Yep, they are allowing 125mph in some sections but it requires a fast accelerating train (such as the AT300s and 397s).Isn't most of this route 110 for non-tilt stock anyway?

Non EPS max speed is 110Isn't most of this route 110 for non-tilt stock anyway?
Just seen a photo On Twitter of Grand Central livery 90 on a LE move from Crewe to Wembley.... so I guess you might be right??Does anyone know if the working below is to move the set currently at Wembley for storage?

Apologies if that working is nothing to do with the Grand Central Mk4 set
Will this be the first time a GC liveried 90 has worked with the Mk4 stock?Just seen a photo On Twitter of Grand Central livery 90 on a LE move from Crewe to Wembley.... so I guess you might be right??
Thanks where are they being painted?90026 & 90029 are the only two painted in GC livery at the moment, with 90020 currently being repainted at Toton
Toton is where they're being repainted. Please someone correct me if I'm wrong, but I think the other 90s due for GC livery are 90021 and 90039Thanks where are they being painted?
I heard the same!Toton is where they're being repainted. Please someone correct me if I'm wrong, but I think the other 90s due for GC livery are 90021 and 90039
90020, 021, 026, 029 and 039 are the GC Class 90s (I’m pretty sure)
I agree, it really stands out from the generic looking livery’s, looking forward to seeing them working on the wcml!I initially thought that GC's livery was too American and had no place in "lil ol' England"
Now I like it and it'll be grand to get to ride one of these nearer me.
It's annoying that the orange is slightly different to the orange on the Class 180s.Photos have been posted on Twitter of the first Mk4 sets in Grand Central livery. Unsure of the source.

Off topic slightly but photos of 90001 in InterCity Swallow have also been posted.

Widnes is doing the overhauls/repaints on the GC sets so presumably this is the next set in.Does anyone know if the working below is to move the set currently at Wembley for storage?

Lets put that into context. A Class 90 with a shorter load will accelerate faster than a Class 90 on load 10, but a Class 390 is no slouch either. So how much faster the short loco hauled set will accelerate to a given speed (in the dry) - may only give it a few seconds advantage to 100/110mph over a 390. And I reckon any driver that has signed both 90's and 390's will tell you the 390's brakes are far more responsive than the loco hauled set. That also applies to starting off - where the loco hauled stock has to wait for the brakes to release. whereas a 390 will not suffer anywhere near such a delay.No, because the 110mph loco is faster accelerating, which is far more useful than the potential to run 15mph faster for some amount of track (which isn't continuous either, meaning that the time saved by the 125mph running is not particularly big as you have to first accelerate to it and then decelerate again to meet the next PSR)

That also applies to starting off - where the loco hauled stock has to wait for the brakes to release. whereas a 390 will not suffer anywhere near such a delay.
And until the 'revised' speed profile has been released, there are many places that loc0-hauled stock will need to brake to a lower speed, whereas the tilting 390's carry on straight through.
Even after some 'straighter' sections of 110mph track are upgraded to 125mph, some of the more severe curves will require non-tilt stock to brake to take those curves at a lower speed - albeit i imagine there may be some marginal improvements in places if the track geometry and cant levels can be adjusted.
As an example - LNER's Class 800's have been running over the EPS sections of the WCML from Carlisle to Corsairs. Now the 800 is a train that actually does accelerate a bit quicker than a 390, but still lost almost five minutes to the tilting 390's due to the higher EPS speeds allowed for 390's - over a distance of 70 miles or so IIRC.
So no - the short Class 90's rate of acceleration will not be that useful at all. In fact i would say that in the all important 60 to 110mph speed range, the 390 is likely to be superior too - which will be important when slowing down from 110mph to lower speed restrictions of 90mph and back again.
That's always assuming there is still some sort of market for Open Access operations once the lockdown is over. If the "franchised" TOCs are all under Government control, why would anybody want to allow private operators to undermine the publicly-funded operators? Right-wing free-market ideologues, yes, but not very many other people would agree with them methinks?
They'd have to specifically revoke the EU TSI legislation that's automatically copypasted into our own law. I'm not sure how politically palatable that would be.
Very true, they tried to order new build ones but they would require modification to be compliant for new builds. I can't remember exactly what was an issue.I'm sure they'd love to use 390s but they can't
All well and good, but the discussion is about why GC chose 90s acceleration over 91s top speed. I'm sure they'd love to use 390s but they can't, so EPS performance is completely irrelevant.
