I guess that the difference is that the 345s and 700s are being built to do very specific jobs for routes that they will be stuck on for the next thirty/forty years - and the high frequency "metro" services they operate aren't going to have any joining/splitting - not can I see any need for shorter trains at off-peak times.

Surely that was an operational choice. After all the commuter trains running on similar lines and services to the Thameslink ones south of the river will operate with varying lengths depending on the time of day, and the previous 319s and 377s on the Thameslink routes weren't fixed length units either

I was under the impression from what I read on Abellio's website that they planned to run the new trains as 2 lots of 5 car sets making 10 coaches on most services.

https://www.abellio.com/news/abellio-invests-ps400-million-new-trains-east-midlands-railway

"Regularly" does not equal "most". At an extreme they could be planning to double one service per day and that would qualify as "regularly" (I don't think it will be that bad but equally I don't think it'll be most).

With the current formations that run, has it been determined that there will be enough trains for when the HSTs are withdrawn with suitable capacity, and later after the Hitachi trains are introduced and the 222s are withdrawn from the franchise?

Agreed! - 'Regularly' does not mean 'most'. It could mean daily on one service. Even 'often' would be subject to the same get out clause . It would have been best for them to say, 'mostly' if that is what they mean or otherwise say, 'sometimes' or on '[x]% of services'or something like that.

As it is they have left it in marketing babble speak which is pretty pointless but to be expected.

Will the new trains for East Midlands railway be similar to the Nova 1 trains for TPE? If not, what are the major differences? TIA

Apparently they will be two metres shorter at 24m per coach, with a "slightly modified nose profile" (Make of that what you will!) with four engines per five car set, so more powerful.

Maybe for another thread but I wonder if we'll see an IET variant on the WCML
What makes you think the Aventra design would have been better than the AT300?
They might even have used the same MTU power pack in the design.
Hitachi has the advantage of an existing bi-mode design and production capability, and supply chain, and that is probably reflected in the price.
Bombardier would have had to set all that up from scratch.
In the past, Bombardier has benefitted many times by having run-on orders for existing EMU designs.
Hitachi is now benefitting in the same way for bi-modes.
The DfT also gets to continue its multi-supplier policy.

I hope my post didn't suggest that I beleived the Aventra would have been better a better choice, because that wasn't my intention

The other advantage, to the train builder, of going for 5 coach units is that if they do find that someone does need then to be 9 coach units they can always sell then some more coaches at a later date.

This would depend on the layout of each set - I'm assuming the layout will be DPTS-MS-MS-MC-DPTF, but with 2 engines in the 2nd & 4th coaches (rather than 1 in each intermediate vehicle).
A 9-car set would probably be DPTS-MS-MS-TS-MS-TS-MC-MF-DPTF, like the 800s, 801s and 802s, but probably with 6 engines rather than 5 (as used on the 800/1s, 800/3s and 802/1s).

Nottingham looks like the poor relation compared to Derby, why not put the Kettering stop from the Nottingham 'fast' service in the the Sheffield semi-fast instead.

I would agree. As proposed in the schedule plan it could actually need three changes of train say from St Albans to Sheffield, at Luton, Kettering and Leicester.

Didn't they say four engines rather than five? That to me suggests a provision has been made with one of the driving vehicles but not the other (due to taking the place of the transformer and/or disabled toilet).

would a coach wth 2x gensets not be too heavy? I suspect there will be only one pantograph trailer vehicle, perhaps in the middle of the consist with driving motored cars each end: DMS-MS-PTS-MS(or MC)-DMF. We'll just have to wait and see what appears from Newton Aycliffe.

Aw, I like the HSTs and 222s. I'm extremely annoyed that Abellio have taken over East Midlands, now things are gonna be way more expensive and they're getting rid of the good trains. Damn it <(

HST speed differentials are more to do with braking performance than weight.

I'm surprised by that.

I recall being told by a BR engineer many years ago that DMUs were determined as being suitable for SP speeds by taking account of factors such as weight, un-sprung/sprung mass, etc, and more recently an Adtranz engineer involved with the development of the Turbostar design told me of some of the problems the company had had in getting 170s approved for SP speeds, and it was far more complicated that just braking performance.

I know Terry Miller used the ability of the original HST concept to be able to brake from 125mph in the same distance as a loco-hauled train took to brake from 100mph, but I guess I automatically assumed that what I was told by engineers about determining which DMUs would be suitable for SP speeds would automatically carry-over to other enhanced speed classifications, and I'm pretty sure that I've seen in print that the reason why 185s can't use HST, SP. MU, or DMU enhanced speeds is primarily because of their weight.

I presume, therefore, that as no 8XX series trains (or class 395 EMUs) are listed in the enhanced permissive speed table in the Sectional Appendix, all have poor braking characteristics; as it another example of a DfT "c**k-up" in issuing a spec which limits the performance of new trains on existing infrastructure, or are they all non-compliant designs?

Awarding the contract for the bi-modes to Hitachi instead of Bombardier was front page news in today's 'Derby Telegraph'; report on line at: https://www.derbytelegraph.co.uk/news/business/derbys-bombardier-misses-out-big-3153355

Another article at:https://www.derbytelegraph.co.uk/news/jobs/shocked-union-fears-derby-job-3154989; anyone know anything about the claim by the Unite official that Bombardier "had the best price, technical solution, and best package overall"? Any foundation for this claim?

The CGI artwork still shows a pantograph on the driving vehicle. I'd agree that a single pantograph on an intermediate vehicle would be more sensible, though.

The trains were getting replaced regardless of who won the franchise, it was part of the Invitation to Tender.

I think the CGI artwork probably shows a standard 80x. A pan on each driving car would provide a bit of redundancy if the rear pan were used and to become damaged, the leading one could be raised. Not that important when you have a diesel back up I know. Not sure why a pan on an intermediate vehicle would be beneficial over the existing position though. Does pan location make a difference?

Yeah it depends how much stock you put in a computer generated image - Though to my eyes the driving car does look a little more "compressed" than previous artists impressions of AT-300s for Great Western and Hull Trains. I was more thinking that a single pantograph car wouldn't result in one of the four diesel engines vying for space with a transformer, rather than specific location in the train: I suppose there'd be nothing stopping having a single pan on one of the driving cars, though as you say having two offers increased redundancy.

The artist's impression also features the revised front, so I would presume that it is the updated version. ;)
