It suddenly dawned on me that the 805s will presumably be 5x26m like the other 80x's. That'll be a less flexible fleet for Chester services - a 5 car will be too long to terminate in the bay platform so would have to occupy 3a while turning around. A 10 car set will be too long for Prestatyn, Colwyn Bay and Bangor unless SDO was used.

5.221 is too short for almost every WCML service, so while that may be operationally inconvenient that's no bad thing.
As long as they don't foul anything, SDO can just be used, this is no great issue in itself.

Will the class 805s be able to change from electric to diesel on the move just like the current GWR and LNER 800s / 802s?
Also, I assume the changeover between the two modes will be at Crewe for Chester & North Wales services, and Wolverhampton for Shrewsbury services.
One final thing, knowing what happened to the TPE Hitachis (originally going to be 803 but changed to 802/2 at the last minute), I have a feeling that the new Avanti WC trains will be at the last minute have their class numbers changed from 805 to 800/4 (for the bi-modes) and 807 to 801/3 or 803/1 (for the electrics).

Definitely not 800 or 801 because those class numbers are only for the DfT spec units. 802/ is still entirely possible.
800/801 were specifically for the IEP program so would be 802/803 most likely's
i've never been a fan of separate classes for different TOC's versions of the same model of train

Yeah same here. It makes no sense to have a completely different class number for a train where there would be no differences at all.
No, and the same with subclasses - that's resulted in some class 66s getting renumbered multiple times when transferred between operators.

Is SDO single door operation?
Using a single door at Bangor would be a nightmare. Can they not use the front or rear half at Prestatyn, Colwyn Bay and Bangor? Or did I miss something and the 10-car sets are not two 5 car sets coupled together?

It’s Selective Door Operation i.e. that only those doors at the platform open.

Oh good. Learned something today 
My local station is Llanfairpwll, where the guard opens a single door.

Avanti are still using 805 and 807 in any correspondence I have seen.
Why not? The class numbers are for operational convenience, not the whim of enthusiasts.
So long as the rolling stock library is happy and it meets the required standards, it really doesn't matter what class number is allocated.

Yeah true. After all it's a Hitachi AT300, the best ever train in the UK! (For me of course)

Don't get it wrong, there are also some things I don't like the AT300 - the unsuitable seats and the weird noise that it makes when it leaves the station that sounds like a plane overhead locker being closed.

That's the sound of the door seal engaging; essentially there's a mechanism which shoves the door leaf up against the frame so that air can't get in (for aerodynamic purposes).
The interiors in general feel like they've been done on the cheap, which they probably have, given it was a DfT spec. The horrid flickery PIS displays, poor quality speakers, nasty lighting and plasticy fixtures.
Here's hoping Avanti have specced something nicer inside. If they have, they might just be among my favourites on the whole network.

Voyagers FWIW have something similar.

I don't think so. Last time I caught a Class 220/221 Vogager I haven't heard such thing.

They do, it's not as audible but you can tell because when you stand by the door you can hear engine noise when stationary but not when it sets off.
Voyagers have plug doors, so should be sealed anyway once fully closed.

They close loosely, then a blow-up seal surrounding the door seals it when you go over 5km/h.
