Most of the 125mph running is or will be under the wires though. Elsewhere, linespeed rarely exceeds 110mph.Beyond Reading that route isn’t 125mph; the MML is a 125mph railway.

The slightly shorter bodyshells (24m instead of 26m) may result in a small weight saving, so the same power plant as the 802s should give the new MML trains a slightly better power to weight ratio. 802s have been running on HST timings for months now and barring failures seem to be able to keep up ok. There's no doubt 222s, like 220s, have a markedly better headline power to weight ratio than the 80x series to date, but how much of this is actually used in anger? Voyager timings on XC in particular were eased markedly following the disaster of the initial Operation Princess timetable, so much so that the trains can operate perfectly satisfactorily with one engine out of service, so perhaps similar timing assumptions were used for the later MML sets.More power might allow hills to be climbed at higher speeds, but speeds on the most hilly bits west of Newton Abbot are restricted by curvature in particular. A higher-powered train is unlikely to improve much on timings.
Which would be a brilliant plan. They could even send one to Sheffield avoiding both Nottingham and Derby if they were to split trains. But I know splitting and joining on route isn’t liked anymore. Not sure why works in many places. Yes you get late portions. But that happens now on Norwich - Liverpool where the are just dropping a set.
Splitting/joining happens a lot on SWR services at a number of places including Guildford, Southampton and Salisbury.
There tends to be a good buffer built into the timetable to allow it to happen, but I've seen it done fairly quickly when the train is running late, which often involves shutting the connection for passengers at least 5 minutes out from the split and trelling them to walk down the platform to make the change.

I suggested something like this a few pages back (or it may have been on one of the other EMR threads). Response was that the franchise is required to run 4TPH between London and Leicester.
Maybe the future service is envisioned as a high frequency 5 car railway but coupling up into 10 car blockbusters so as make best use of paths in the section shared with Thameslink?Does anyone know whether with a bit of timetabling magic these will be able to run in 10 car formations on existing routes?
A failure right from the start under Virgin/Stagecoach, but wasn't helped when XC & VTWC were then split and VT got 20 x Class 221s for West Coast use and the XC services were already well under capacity with 4 & 5 car Class 220/221s plus half a dozen HSTs. Look how there services struggle now as i'm sure a lot of you have found out on your travels.
Did Stadler offer an achievable product that will attain 125mph in both electric and diesel mode, in time equal to, or quicker than a 222? Stadlers bi-mode utilises a "pod" in the middle of the train. What would be the impact of this on capacity, and restricted platform lengths? Did Stadler offer a variant with two sets of passenger doors per side per carriage?New post regarding this on my site. Thoughts appreciated, so I can add to any opinions.
I personally would have preferred FLIRT trains from Stadler, but I’m a fan of the Class 800 design, albeit not the way they have been introduced across some areas!
Back in topic, the 5-car length for EM is dictated by St Pancras - many EM trains are currently 5-car and not overcrowded. A uniform fleet should help with maximising its use.

Who says they are not overcrowded?
I have had many experiences on the 222 in my year of commuting and miscellaneous journeys, of many being full and standing, and I fear the same problem faced on these happening to the newly introduced trains that are replacing the 222s.
Notably the 16:27 and the 16:52 from Loughborough to London St. Pancras, both 5-car 222s, that are beyond capacity with passengers standing in the aisle. Worse on Fridays as people also have luggage. Some have resulted to standing in first class. Without a reservation, I can garunteed I'll be standing on my journey to London unless I can strategically stand in the center of a carriage and hope people get off in Leicester, 10 minutes from Loughborough. Should these trains be doubled up, I don't see how the load can be shared between the two without a gangway. The 16:24 only has two stops so there isn't much opportunity to switch trains, that is hoping the other isn't as busy.
That is my biggest problem with joined trains with no gangway. As mentioned by others who seem to have had similar experiences - I haven't been on a HST on the Midland Mainline without a seat - ever.
I do hope some of these trains to be introduced can be lengthened.
The MML has been historically unable to keep its train formations the same way round. Usually the units themselves are in the correct order when coupled together, but either unit can have First Class north or south. Having two coupled units may actually make this better, as you can't be more than five coaches from where you expected to be! Also both Nottingham and Leicester have entrances at the extreme London end of the platforms, as obviously does St Pancras, so particularly on Nottingham services the loadings are likely to be quite uneven.Those who travel regularly will know which half of the train is likely to be busier and so will position themselves accordingly.
Even if that result in just 10% being in the other set (& given people pre booking seats will be allocated seats in both units the figure will likely be higher, especially if the booking engine is required to mostly book seats into the quieter half first if things continue to be a problem) that's probably enough to remove the worst of the overcrowding, with the booking engine able to remove the rest with the way it allocates seats.
There are very few routes where travel against peak or during extreme hours would not bring the impression that capacity is sufficient. To suggest that the current length of trains is sufficient when never travelling at peak times is like suggesting that the M25 is always free-flowing based on journeys at 2am.Many services may be overcrowded - I wouldn't deny that - many are not.
5-car has been sufficient for almost all of the times I have been on a 222 but typically that is typically against peak flows. I hope they will run 10-car on those where a 5-car is not enough.
You make the key point that the Corby service will hopefully make capacity at the London end fit better to demand.

GWML timings are very slack - and this is seen in the new timetable. We know for instance that an 802 accelerating from rest to 125mph over 10 miles is about a minute quicker than an HST. But that's it! as both trains run at the same maximum speed of 125mph, the only further time gain is from the next station stop, or from low speed restrictions. But try and explain why from the December timetable Paddington to Reading will now be only 22 mins with no recovery time minutes as opposed to 25 minutes currently inclusive of 1 minute recovery time! In essence, HST's could easily meet a 23 minute timing with no issues en route, and 22.5 min is possible! But 800's on diesel couldn't do that - and with engines out - you are looking at 26 minute+!!!The slightly shorter bodyshells (24m instead of 26m) may result in a small weight saving, so the same power plant as the 802s should give the new MML trains a slightly better power to weight ratio. 802s have been running on HST timings for months now and barring failures seem to be able to keep up ok.

Which is for the simple reason that services to Sheffield/Leeds can run via Derby or with a reversal at Nottingham and a set arriving at Etches Park can be turned if starts from Nottingham the next day.The MML has been historically unable to keep its train formations the same way round.

Will the new IEPs just replace the HSTs?
I've read in this thread that people don't think 33 units will be enough. Don't want to bring back an old argument but surely they should be future proofing by providing more units.From my understanding, the IETs will replace both the HSTs and the Class 222 Meridian units.
