Regarding the topic title 'Best UK Train Manufacturer' I'm not really sure there is a UK Manufacturer anymore - Bombardier/Alstom is probably the closest though so that's who I voted for.
I'd consider the Pendolino the exception to prove the rule, looking at the other things Alstom has produced.
It's not like other manufacturers can't build tilting stock. We just haven't seen any of it in this country because there is only a very limited scope to use the tilting capability.
The Pendolino isn't the only tilting stock in service in this country - the Avanti Super Voyagers tilt and were built by Bombardier. Of the two types, I actually think the Super Voyager is the superior design (because the Pendolino windows are pathetically narrow slits) but unfortunately they were built for the underinvested routes and hence are diesel powered and too short. Such a shame we didn't get 9-car and 11-car EMU versions of the Super Voyagers instead of the Pendolinos.
while I do quite like the 397 and 80x, I'd take a GA IC FLIRT any day, it's just a better quality product with a far better ride, plus the game-changer of level boarding. And I'm not sure how the very comfortable FISA LEAN isn't an InterCity seat, it's far better than the Sophia as in 397s and 80x.
There are two different things here, there is the train and there is the seat. The Fanisa Sophia is
not (or shouldn't be seen as) an InterCity seat, but the class 397s and 80x could still be an InterCity train design - they just need the seats replaced. I've not used them much, but I think with decent seats (and ideally plug doors, but it's presumably too late for that now) the 9-car 80x could be a good InterCity train. I've yet to go on a 397, but again the design in general should not be judged solely on the seats (although their suitability for long-distance services in their current guise certainly should - we need GBR to start the fightback against awful seats promissed in the Williams-Shapps plan ASAP).
There's no demand for such a train.
GWR and LNER had to take the government ordered-80x; TPE, EMR and Avanti have gone the same way in slightly modified form.
HS2 will take the Hitachi-Alstom HS design.
That sorts out inter-city stock for a generation.
There isn't anybody else, unless a new open access operator starts up.
Maybe XC at some point? Scotrail's HST replacement? SWR to Salisbury and beyond?
It would probably depend on what happens to the Voyager/Meridian fleets.
The 222s will be due for replacement around 2040, XC, GWR and ScotRail will all need something to replace IC125s. The nearly 200 (it could be 200 if the diesel engines from the 801s were removed and repurposed) Hitachi InterCity bi-modes already ordered should be plenty if sense finally prevails and the mainlines are scheduled for electrification - units (or the diesel engines from under them) from routes nearest the front of the queue for wires (eg. Oxford, Bristol and Swansea) could be cascaded to XC with new electric-only 80x built for the likes of GWR. Either way there will be some more InterCity stock needed, but please god no more diesel engines for InterCity stock.
I think if ScotRail had to opt to purchase new trains for their intercity fleet then they would likely opt for another of the 80x series simply because it's a proven design that you can order off the shelf. That is unless there are conditions unique to their network that Hitachi somehow couldn't meet.
Hopefully ScotRail will order straight EMUs for that purpose (perhaps with temporary batteries if they want to retire the IC125s before Aberdeen-Inverness is fully wired and want to maintain full InterCity stock throughout the transition rather than stepping down to regional express units for a bit). Also, one hopes that as with the EGIP units (Hitachi AT-200) ScotRail would insist on plug doors for any future 80x for ScotRail rather than the sliding type used on the existing 80x which give a cheap-and-nasty impression.
As for SWR to Salisbury my first instinct would be that they just ordered more Aventras. As the operator of some of the busiest commuter networks in the country they would probably want a train they can also use for stopping services around London. I could be wrong but I trust more knowledge forum members will correct me on that.
The Aventra hasn't got a diesel/bi-mode option.
The new Alstom might offer something different, of course.
Bombardier offered bi-mode Aventras for the MML but EMR went with the class 810s from Hitachi instead.
I think it will likely be years before operators take interest in hydrogen powered Aventras. The fact there is also an option for bi-mode Aventras probably doesn't help the case seeing as bi-mode trains are already a proven technology for operators wanting to run on electric and non-electric routes.
This makes me think of the East Midlands franchise commitment to trial hydrogen trains on the MML. Obviously wasn’t going to come to fruition - emergency measures effectively ending franchising aside, I couldn’t imagine any of those Aventras running MML IC services!
Would Melton Mowbray - Derby count as being 'the MML' sufficiently to cover that commitment to trial hydrogen units I wonder? That said, the 10 hydrogen Aventras proposed as a speculative build have a fatal flaw if you ask me in that they are
not multi-mode units. Apparently, no pantograph is planned meaning they would be 'burning' hydrogen under the wires. The only routes where Network Rail's TDNS recommended hydrogen units without running under the wires for miles and miles were some GA services out of Norwich.
Very nice travelling environment and comfortable too. I just wish they'd stop locking the internal doors open on the 745s, they are much cosier with them shut, almost like being in a compartment.
Do they even have internal doors? If so where and how many?
