TRU specced for 7*26 m or 8* 24 m sets. A 5* 24 m would be foul of various crossovers in a pair. Even on today's traffic levels 5*24 m would run heavily loaded with standees so one extra train per hour is doing a LOT of work on forecast in eight years time.
Remember it's moving to 6 trains per hour in the core from Manchester to Leeds. That's 1800 seats per hour. TRU is also specced to allow for future expansion. More carriages can be ordered in future.

It does rather look as though the large extra costs for batteries and charging at outstations has caused them to run out of money and spec to five vehicles per set rather than six.
Who knows? That seems an entirely speculative comment.

More than likely the 90 miles is contracted range including battery degradation
There should have been a complex bit of trade-off work here. I am sure the battery degradation risk sits entirely with Alstom. As long as the train leaves the depot with enough battery range and isn't overweight etc., TPE probably do not care. It's easiest to think of the extreme scenarios and then realise that there's a sweetspot somewhere in between. For example:

1. Just enough battery on day 1, but the moment they get a few bad modules/a bit of degradation they're straight into a rolling programme of pack/module replacement
2. Enough battery to meet the requirement after 40 or more years of service. However doing this means the train is - for most of its life - carrying around battery it does not actually need, that was probably cheaper to not buy for 30 years, and then stored on a shelf in the depot.

If it turns out this order isn't enough, how easily could an add-on be ordered?
I haven't seen anything today. The original procurement had options but haven't seen evidence either way on whether it has been included.

Even if not, if the idea is to extend existing trains than it's likely a new contract could be directly awarded to Alstom because nobody else can supply the additional carriages (Schedule 5 of the Procurement Act 2023 sets this stuff out). This might also work for a small number of additional trains because of the overwhelming disbenefits of a microfleet.

Yes how many times are these trains going to get re-announced over the next few years...
They might also be Class 810 levels of late, which may give several additional years for media reannouncements (and speculation here!)

i was just responding to a query as to whether Alstom (pre-the Bombardier takeover) had supplied anything to the UK in the past 25 years other than the extra Pendolinos.
My question wasn’t genuine – I was merely pointing out that it wasn’t fair to talk about suggested reliability of Alstom trains when the UK hadn’t received any for a long time (with a lot of Alstom reliability issues actually being mostly UK-centered).

New trains to suit upgraded infrastructure; GWR doesn't have an equivalent to the TransPennine Route Upgrade.
Although GWR do have routes that a similar spec train in would be ideal for eg Cardiff-Portsmouth or Bristol-Oxford

I realise former would need 750v dc to. (but of course GWR also serves Weymouth and Gatwick too in third rail areas)

And it's entirely possible that GWR will get something like the TPE train, the question is good much more electrification will be needed to make that viable.

And no, if NPR/HS3 ever goes ahead, these trains won't be running on it because they'll still be running on these routes.
At least some of the services that these new trains are planned to operate on will be diverted on to NPR. The classic line will maintain a service but it will be relatively limited (e.g. 2tph) with most services being diverted newly proposed infrastructure from Marsden to Manchester and onward to Liverpool. There's talk of the Manchester to Liverpool section opening in the early 2040s meaning these new trains won't even be 10 years old. It seems a strange decision not to make them compatible with NPR proposals.

Also, how many Redcar/Scarborough/Hull trains run as 6 x 185 today? I would guess most are 3 car, so at least off peak service seats are increased, with hopefully fares to encourage them to be filled.
In my experience from my recent and on-going Leeds-York commute, 6 to/from Redcar, 3 to/from Scarborough. I was in Selby on Wednesday, think I saw 802s to/from Hull.

I'm confident that there are shady torture chambers with more comfortable seating than 185s, so I'll come back to you on that one!
The last refresh improved the internals considerably on what we go from new. And they're better than the stained, torn cloth on the 802s.

My concern is that it's 29 units, which is approaching microfleet size in my book. Hopefully there will be further orders from elsewhere, which will keep the jigs running and possibly see extra cars built (and plenty of spares for repairs).

I bet someone at EMR is looking at this and thinking "we could have had them!"

2034 is a long way off.

Lots can happen. Especally with GBR.

I'm going to throw a ringer in here.

29 new 5car units.

There are 12 x 397s and 19 x 802/2s = 31 units all 5car.

A single fleet type is more efficient, 29 could replace 31, is it possible here this is part of a grander plan that these new units are for a cascade ?

Yes, there is no evidence for my suggestion - BUT equally there is no other evidence anywhere of any other cascade, within the current TP operation, or NT or anyone else, merely chatter suggestions. There may be a replan of services and operators that is not yet in the public domain.

There 110mph max on electric and 100mph on batteries?, without enough range for EMR, so not an option really.

The 110mph max speed rules that out, these units are for the Redcar / Scarbourgh / Hull services replacing the North TPE 185's.

You mean like I said in my post? ;)
You said there is one extra train per hour - that's not right, as the 5 trains per hour at the moment include the stopper that TP also runs but won't in the future.

Post-TRU, TP will run 6 fast and semi-fast trains, and the stoppers will be taken on by Northern with 2tph from Huddersfield to Leeds (not sure how many will run from Manc to Huddersfield).

So as far as the fast / semi-fast service goes, it's increasing from 4 tph, some of which are 3-car, to 6 tph all of which will be 5-car. It's a 50% uplift in long distance capacity, with all-stops capacity doubling at least (depending on what trains Northern runs).

I hope that the trains get busy and have to be extended. Some way off yet though.

That isn't correct though. The extra stopper isn't funded, it may still be more stops at peak times in fast trains. Same goes for Castleford - York.

The government is spending money on developing a business case for NPR currently and Rachel Reeves committed £45 billion to it. Doesn't mean it's definitely going to happen but the government should be at least be ordering rolling stock compatible with NPR.

If it turns out this order isn't enough, how easily could an add-on be ordered? I would hope quite easily before production begins, and maybe early on in production, but presumably much harder once the 29 are nearly finished.
How often is that said, in hope, and how often does it happen

People said the same about the 185 and they said the same with the 195s, they probably said the same about the Voyagers as well.

In reality the government of the day will procrastinate for so long that the option will expire, and then after about 10 years of overcrowding, they will order some sort of new micro fleet to be delivered 10 years after that.

I thought TRU was supposed to be game changing. If it was there wouldn’t be all this need for various posters to be doing all this mathematical gymnastics to explain how it’s actually just about ok

That's not really feasible though as there's nothing to be 'compatible' with yet.

So TPE have a bunch of 20 year old DMUs that still work fine yet are getting new trains, whilst GWR are having to deal with much older DMUs but seeminly have no hope of getting a new fleet.
GWR is still due to get new trains under Project Churchward, which is likely to deliver around the same time as the new TPX trains come onstream.
TPX is getting new trains because the route is being significantly upgraded and the existing fleet wouldn't be able to fulfil the objective of the upgrade.
GWR are in the position where they are actively having to cancel a tonne of services all the time and now have had to make a timetable change all because of their rolling stock situation.
Something tells me TPE aren't in a situation that bad - yet are getting new trains for upgrades.
GWR are in the process of receiving a bunch of class 175s – the only reason they are having the current problems is because the 175s are in a worse state after being in storage than expected. This was unforeseen and so of course they couldn't speed-run a 5-year procurement process for new trains in a few weeks – and it should only be a temporary hiccup anyway, the 175s should be brought up to full working order soon, meaning that GWR will again have a full fleet so no further cancellations needed.
And when the GWR DMUs (158s and 165/166's) would be coming upto 45 years old.
They are due to be replaced within that window.

As someone pointed out, we don’t know the operational set up as 5 car extra services between York and Manchester might grown the overall capacity.
Also would 10 with SDO and then split at York be options for Scarborough and Saltburn services?
Running services through the core at 5+5 and then splitting/joining at York would cause a number of problems, including (a) being too long for some stations along the way, (ii) increased risk of delays and disruption, including blocking platforms in York when waiting for a late-running portion, (3) unless you're going to then order more trains to run through the core, you're not increasing capacity, just consolidating it into fewer, longer trains instead of more frequent but shorter trains, so I'm not sure what the gain is. Splitting/joining is a real headache for the railways, even though it appeals to armchair planners, which is why it is used very sparingly.

This is a misunderstanding.

The announcement on Northern Powerhouse Rail on 14 January 2026 is here:


Government announces the biggest transformation to travel in the North in a generation as the Chancellor sets out new Northern Growth Strategy and promises the renewal of Britain to make all parts of the country better off.
The key paragraphs on funding say this:

Northern Powerhouse Rail will be kept within a fair funding envelope over its entire construction period to ensure it remains good value for taxpayers both now and in the future, avoiding a repeat of past mistakes where major projects like HS2 have gone significantly over budget.

A funding cap of £45 billion will be set for the programme. £1.1 billion over the Spending Review period is the first stage of this, allowing development and design work to progress and enabling the creation of a detailed delivery plan which will include timings.

The £45bn figure is a cap, not a commitment. The committed funding is £1.1bn.

Yes because you're can't commit funding that far into the future but the government's plan is to deliver this, £1.1bn in development funding is a big commitment, so rolling stock should reflect that commitment.

We don't know this government's plan, Rachel Reeves is no longer the Chancellor. There is no commitment beyond the design funding.

Given that the £1.1bn of committed funding has not yet produced a design, there is no commitment for this rolling stock order to reflect.

GWR are also getting 158s from TFW once more 197s enter service to displace the 158s.
One problem here is I'm pretty sure only two platforms at York would be usable for such a split/join, as all the other through platforms don't have a connection to the Scarborough line, which could be capacity-limiting overall.
You'd be blocking Platforms 5 and/or 3* to do this, both of which are used by LNER and XC long distance services as well as TPE from Newcastle.

*Platform 3 would need to be used instead of Platform 4 so the Teeside service could leave York. Platform 4 only has access to the Scarborough to the north. The train would need to be uncoupled on Platform 3, the Teeside service could still access the ECML and the Scarborough service would need to run up Platform 4 onto the Scarborough line. The same setup is not needed with Platform 5 as Platform 5B (northern end of Platform 5) has access to both the Scarborough Line and the ECML.

In short, too complicated with no gains. Running the two services separately throughout the core provides an enhanced frequency thus providing more journey options and spreads out demand.

A lot of people have missed that the existing six cars carry a lot of standing load. The layout changes aren't particularly important for that as what's lost in narrower doors will partly be made up for in removing the step at some stations.

What is a problem is the loss of a whole vehicle given the increase in seating is ~0. So all of the extra capacity is riding on the one extra fast train between Leeds and Manchester (provisionally a Hull - Manchester Piccadilly).

TRU specced for 7*26 m or 8* 24 m sets. A 5* 24 m would be foul of various crossovers in a pair. Even on today's traffic levels 5*24 m would run heavily loaded with standees so one extra train per hour is doing a LOT of work on forecast in eight years time.

It does rather look as though the large extra costs for batteries and charging at outstations has caused them to run out of money and spec to five vehicles per set rather than six. It proves once again that any savings of opex from going from DMU to battery are illusory, except for short, low speed routes.

By contrast the extra cost of speed above 110 would never have been justified for these units. TRU are only lifting permissible speed above this between Church Fenton and Colton Jn, so York - Church Fenton would be the only short section they could regularly run above 110, plus whatever very limited occasions they may run non-stop through Thirsk.

The DfT will have crunched the numbers. Without checking back through multiple threads, it seems a number of train length assumptions have been iterated through, over the TRU infrastructure development, and rolling stock specification and procurement exercise. When you sign on the dotted line with £££s written in front of you you don't just spend willy nilly. The fiscal signals are clear, there can be no largesse to the railway. The capacity requirement wasn't 6, it was 3+x, and the x could have been less than 3. It's clear x=2 became the best compromise answer given current fiscal realities and growth forecasts. Fast train frequency going up from 4 to 6tph is still a significant capacity boost even with 5-car trains.

At least some of the services that these new trains are planned to operate on will be diverted on to NPR. The classic line will maintain a service but it will be relatively limited (e.g. 2tph) with most services being diverted newly proposed infrastructure from Marsden to Manchester and onward to Liverpool. There's talk of the Manchester to Liverpool section opening in the early 2040s meaning these new trains won't even be 10 years old. It seems a strange decision not to make them compatible with NPR proposals.

And yet, the government has made a very conscious decision not to procure NPR-ready rolling stock. That tells you all you need to know. There will be no NPR this side of 2050, or 2060, or ever (in its currently published form).

Burnham is a big backer of NPR. It's not rocket science as to what the requirements will be. They've been fairly consistent over the decade.

What's the point of spending £1 billion on development of new lines and ordering incompatible rolling stock with line, it's an inconsistent decision. Its not as if procuring a 140mph train is going to cost a lot, it'll be far cheaper than ordering a new fleet. There may well be a plan that hasn't been made public yet, I know there are elements of NPR that haven't been made public, but it seems like a strange move.

That's really tremendous logic. Any rail upgrade that requires the deployment of... SHOCK HORROR!... mathematics!... to work out the capacity increase is basically pointless. How else do expect to do it? Vibes?

And yet? Borrowing rates have been edging upwards ever since Burnham became Prime Minister. Thankfully the occupier of No. 11 is a Westminster man through and through.

I'd be amazed if NPR as is published ever sees the light of day. It's too politically toxic to just cancel. £1bn development money is small change for keeping excitable local politicians shut up. And who's to say the £1bn doesn't include studies of alternatives?
