If the Cleethorpes service is approved, this will make (un) coupling sets at Doncaster far easier. Honestly not bothered that it's more IETs, if they run, then they're certainly an upgrade to the current offering. They're also far better for the environment than running 180s under the wires for some 200 miles!


Depends on their paths for the ECML too!
IETS are also cleared for a a LOT of the route in which these would be intended to operate on, if not all, so introduction to service should be fairly straight forward. Just the usual crew training.

Personally I think speculating on class numbers is a bit pointless.

Having said that, all previous 26m Hitachi AT300s are numbered in the 80x series (800, 801, 802, 803, 805, 807), so in my view the obvious numbers to be used, assuming it gets a new class number at all and it isn't just another set of 802s or 805s, would be 806, 808, or 809.

The LNER CAF trains are Class 897 so I wonder if these new Hitachi trains will be Class 812, Class 880 or even the first Class 900 train?

Logically, 808, having skipped 804 (was that the original number given to the 810s?) and 806. All of the bi-modes are even numbered apart from the 805s. But class numbering is so weird now, they might be 802/3s, 370s or 140s. Who knows?

Went from "they need new trains" to "we've ordered new trains" in 6 days (obviously behind the scenes negotiations have been going on longer).
Wish Northern could be that fast in selecting their new trains, we've already been waiting years!
Exactly this, self imposed public sector procurement rules are damaging what needs to be swifter action.

Positive news all around it seems.

One person on the social media site formerly known as Twitter was very sweary as it was 800s and not a Stadler Flirt, for boarding and wheelchair reasons.

Stadler - 720, 555 and 777 delays
Bombardier/Alstom - 701 and 720 delays.

It is not just a hitachi issue with delays.

They aren't pressurised. They're pressure sealed, which is more about preventing pressure waves affecting the train as another passes, e.g. in a tunnel. The sliding doors are indeed cammed into a seal above 5km/h, but it's not like an aircraft and it can be done with plug doors - it's noticeable on a Voyager for instance if you're standing by the door.

it's just their preference because it's what Japan always does (the AT300 is basically a tweaking of an existing Japanese design). And I don't really see an issue with it to be honest - the doors are at least quick to open, far quicker than the really sluggish ones on Desiros. Yes, you end up with a door pocket, but that's an ideal place to put a luggage rack anyway (NOT seats!)
They also haven’t used Plug Doors because, until the ScotRail order, Hitachi themselves considered the plug door to be considered an unreliable outdated European feature. Had they got their way with the 385s, they too would have had sliding doors. It took for a lot of convincing from ScotRail, and IFE, that Plug Doors can be reliable. Had they won various joint tube or metro orders they’d have to have come up with some solution to that too. Though it’s only until the 385/ that they haven’t.

And the doors are the most common fault in the 385s. In fact it's the only fault I've ever had. Saying that, any fault is a rare thing on a 385. (Apart from the plug sockets which keep getting kicked and broken)

Is there any indication where these units will be maintained? Assume Heaton (As LNER use), Bounds Green (Home depot - imagine space as not LNER home depot) and possibly Neville Hill (Again as do LNER for light servicing)? I cannot see them using Crofton as this is an Alstom Depot or Tyne Yard.

How is it a bad commerical judgment? They get to charge more for a non-standard order and it keeps more people employed for longer. More non-standard orders would be great for them.
There has been no repeat orders from any regular operator (excluding private open access), so possibly they have lost reputation or discouraged others from getting a business case due to the higher prices.

Commercially they now have a troublesome order for 33 class 810s, which might result in lots of delay compensation, reducing profit (or even causing a loss). When Rock Rail accounts get published amount might become public.

Of course hindsight might have led to a different judgement about if the 810 order was worth it, compared to holding out for another 26m version order

Can anyone explain the difference exactly between plug and sliding doors? Apologies for my ignorance!
A sliding door opens by sliding along its centre-line into a recess built into the vehicle body and so is recessed in from the body side. A plug door opens by moving outwards from the vehicle body then sliding alongside it. When closed, the plug-door gives a more streamlined appearance and should reduce wind noise when the train is moving. Plug-door as on class 390, sliding door as on class 150.

There is little reason to believe they'll be anything except 80x. I imagine the tri-mode design of the units will prevent it from being part of an existing class, but until we hear otherwise it's probably going to be the next in sequence up from 800... If only Avanti hadn't broken it with the 805s and 807s.

So you're looking at the train sat on the platform.
The doors are open.
If you can see them - they're plug doors.
If you can't see them - they're pocket doors (what's been described here as sliding doors)

An example of two very similar trains where a clear differentiator is the doors is 375 (plug) and 376 (pocket).

Image description: Aforementioned doors.

Hitachi, being a Japanese company, typically use pocket doors and this is what the 80x have, and that will include this order by Grand Central. It's what you get on the Shinkansen, but it's not standard for intercity stock in Europe. 390, 397, IC225, 22x, 444, etc all have the more streamlined plug doors. It's also why the first set of seats on 80x have no window, because where the window would be is the pocket where the door hides when open.

As much as I want all new trains to have level boarding, it was unlikely to expect a "new design", and while a FLIRT was possible I'm not surprised it wasn't the option selected.

I would imagine they are cleared for the Sunderland route outright due to LNER running Durham Coast diverts, and probably already cleared for parts of the West Yorkshire route with a mix of TPE (i.e. Wakefield Kirkgate - Brighouse) & LNER (assuming LNER have run an Azuma via the Knottingley area).

Slightly easier than going for a brand new design which will cost more money to clear on the routes they run.

Presumably being OA they probably also didn't have to put anything up for tender, they can just order something and buy it?

Exactly this, self imposed public sector procurement rules are damaging what needs to be swifter action.

They were tendered, as per the law. And this has been several years in the making. But, obviously, GC have kept it quiet for reasons of commercial confidentiality.


The practical alternative for a 125mph bi-mode unit was CAF I would have thought, based on the LNER order, but maybe the battery option was not available.

The LNER CAF units are coming with batteries.

Trimodes are excellent news. Hopefully encouraging a retrofit to the older fleet to reduce in station emissions and noise.

That‘s ‘Durham Coast’ diverts. LNER have operated diversionary services on the route for some years, since soon after the introduction of their 80x classes, but although the Sunderland passenger service was withdrawn they still run through Sunderland to provide the ECS for their limited Middlesbrough services.

The Tyne Valley (also cleared) is the route west of Newcastle to Carlisle, also cleared for diversions to from Scotland.

We have unlocked the Speculative Thread so posters can post their suggestions as to what they would liked to have seen etc with this order.

This thread should be confined to discussion of the actual order itself.

thanks

Understand that so the question is public sector procurement legislation working?

Absolutely, whilst the IET is bland, its a proven product on the ECML, you can see why any "Long-Distance" operator would select them!

I believe that various iterations of the 80X have ran on all the routes that Grand Central operates. I seem to recall that a few LNER Azumas have been through Knottingley and TPE have sent one of their Class 802s to Bradford Interchange.

Apologies if I've missed an answer on this: what different power source combos can be achieved with this planned tri-mode fleet? Could say the battery and diesel each run on their own as well as simultaneously?

The second image of the exterior of the train shows 7 carriages, I assume this is either a rendering error or that they are indeed going for a mix of 5/7 carriages?

Goodbye, comfortable seats on Grand Central...

It'll just be the render. They are definitely going to be five-coach sets. There have been plenty of train renders (including those by Hitachi) which are incorrect in various ways.

I would think that the battery is particulatory useful.when running under diesel as it allows regenerative braking to be used to charge the batteries. The batteries would also allow the diesel engines to run at a more consistent level and when acceleration is required the batteries will kick in to provide additional power to the motors.

When the train is going more slowly the diesel engines can charge the batteries so that the diesel engines are operating in their most economic power range.

When entering stations at low speed the battery could power the train completely. Presumably also the batteries can provide hotel power when stationary so the diesel engines can be turned off completely.

I'm assuming that these units are likely to.be based on the 805s which are the most recent standard bimode units.

The 805s can accelerate more rapidly when running on electric than when the power is provided by the the three diesel engines so it is possible that with the battery pack and two diesels that train could get a bit more acceleration than a purely diesel configuration for short periods..

There may also be an ability to charge the batteries when running under the wires so that there can be a mains contribution when running off the wires but I would be surprised if the single battery pack per unit could drive the train for a significant distance. The regenerative braking charging the battery would be useful when running on OHLE.

( I don't have hard info on what has actually been ordered. This is a bit speculative based on the general performance of batteries )
