I've increasingly little faith in the IEP specification offering anything that makes it comparable to being a direct replacement for HSTs...

I think the best we can hope for is a Pendolino style kitchen at the first class end with a shop/buffet somewhere in the middle of the train. I would also not be surprised if the 5-car bi-mode only had a shop/buffet in the style of the 180s.

The DfT and the TOCs are not interested in offering on board catering of anything like that which was available under BR, so why would they equip the IEP to be able to provide it?

Omitting a buffet?

On a long distance Intercity service?

Surely they wouldn't! :shock:






...Would they? :(
XC seem to think it's fine. I'm still very surprised that no TOC has thought of installing a vending maching though, would remove the need for a trolley and in any event there are often times when the trolley can't get through the train.

We don't know how much power the GWML OHL will be able to give. I'm sure you know that not all OHL instllations give the same amount of power.

Are you seriously suggesting that they're going to electrify the GWML so that it can only give exactly the amount of power needed for the IEP trains minus the 'hotel' power on the bi-modes. I'm not buying it - the OHL will be developed so it can supply ample power not only to IEP but to any other electric trains that might be running down there. So either the design of this train is fundamentally flawed or they've got it wrong (i.e. a civil servant thought it sounded like a nice idea).

I'm not I just know that not all OHL installations are the same, I don't know where the how many OHL supply stations there will be either. Is there any other reason you can think of that would require a diesel engine to power the auxilliary systems?

I think Zoe and Ainsworth74 have both hit the nail on the head here. None of this paints a particularly rosy picture for the future of Intercity rail travel in the UK beyond it being a basic mass mover of people from one place to another. We're talking about using these trains on the "Cheiftain" to Inverness and the "Northern Lights" to Aberdeen, and London to Cardiff/Swansea is hardly a short hop either, and yet it remains to be seen if there'll be much in the way of a provision for catering and on board comforts. Anything more than a "no frills" service seems to be an unfashionable objective to follow in the present day.

No! That's why I say it's ridiculous. :)

I seem to remember the Eurostars were limited to 100 mph on the ECML. Considering that bi-mode trains will be running on the ECML, could this be related?

People want these rock bottom airline style advance fares though. If you want no frills airline style fares then it's reasonable that you have a no frills airline style travel experience.

No, as has been discussed on another thread in the last couple of days, the power supply has since been upgraded.

I wonder, actually, if the idea of using the diesel engine to provide 'hotel' power is a clever (possibly the wrong choice of word!) cover up for the realisation that the diesel engine cannot simply be 'started up' at any time. I seem to recall reading in Informed Sources a while back that the DfT liked the idea of the diesel generator switching on halfway up hills and suchlike to give the train a boost, and he explained why this was not possible - the MTU engine in a Class 43, for instance, needs to be 'warmed through' (or something, I'm no engineer!) for around 40 minutes before the engine can be started up from cold - perhaps the bi-mode's engine will be similar to this, and therefore the only practical option will be to start it up in the morning at the depot and leave it running all day...

Another point: It's all very well having five or ten coach trains but just how much of this will be First Class? There will be times I expect when we see a single five car bi-mode train running and I do hope we don't end up with two coaches taken up with First Class.

It's not a long distance Intercity service. It's a medium-distance commuter service, which happens to continue to various extra faraway places. Look at FGW's HST interiors, and to some extent, what the XC network has become.

I doubt there will be any catering on the 5-car services beyond a trolley in one of the two units. If there are 10-car units then probably a mini-buffet style affair.

Also I hope to god that we won't have underfloor engines throbbing away even under the wires! :shock:

If we do it will only on the bi-mode and only one engine of the three engines.

As for platforms being too short, why don't they just build trains pretty much the same length as they are on the GWML now, though with an extra standard class carriage to take advantage of the space saved by not having two powercars? We don't have to get hung up on 'ten coaches'...

Even then, SDO would remove any such problem.

The stupid thing is that most mainline stations could happily take much longer trains - look how much spare platform space there is at Reading or Didcot - with the exception of Paddington, where platforms have been shortened to make space for a shanty town of greasemongers, charlatans and emporia of tat.

I beleive you'd need to employ more staff though, for example if one member of safety critical staff can deal with five coaches then a ten coach train you will only need one dispatcher on the platform as the guard can deal with the other five. More than ten and you'd need a second dispatcher.

OK, didn't know that - though on very busy services trains longer than 10 coaches would still be welcome (and justify the extra staff), since there is very limited capacity on the line.

How many staff are required to dispatch a 12 (or is it 15?) coach Desiro on SWT?

I'd like to know how the EMU version is going to meet the requirment to split en route. I would think the bi-mode version meets this requirment by splitting a 2 x 5 coach unit. We know that 2 tph will run from London to Bristol Temple Meads via Badminton so it's possible this could run as ten coaches to Bristol Parkway where it would split with five running to Cardiff and the other five to Temple Meads.

they would have to sort out the line up filton bank before running any more trains down it. it should be 3/4 tracks between Parson st & Filton Abbey wood

Not everybody is after the rock bottom airline style advance fares though. It’s understandable that the approach to design for on-train facilities has moved towards the “fit as many seats in as possible” approach, to seat as many passengers as possible who are attracted by low fares, raking in maximum revenue by providing a basic service with very few “extras”, but it is not always preferable.

It's not a long distance Intercity service. It's a medium-distance commuter service, which happens to continue to various extra faraway places. Look at FGW's HST interiors, and to some extent, what the XC network has become.

There seems to be a bias towards aiming train design at the journeys made over intermediate sections of the whole route, which is appropriate in terms of the number of passengers who make partial journeys compared to the number travelling the whole length of a train service, but by looking at medium to long distance services this way it makes it easy to forget the nature of the service provided as a whole: In my opinion trains should be designed with the needs of the passenger who is making the complete end to end journey in mind, rather than just aiming to satisfy the majority of passengers travelling the shorter intermediate journeys. Remember that these trains are earmarked for the lengthy London to Aberdeen and Inverness services as well as GWML.

Indeed but I find it's no coincidence that catering facilities started to decline at the same time as walk-on fares went through the roof and advance fares were widely introduced. It was also around this time that some TOCs decided to pack as manys seats as possible into the coaches. If advance fares were increased or even withdrawn in some cases in return for lower walk-on fares and better catering facilities you'd hear no end of complaints.

I quite agree with this - my point was that the service isn't designed for this purpose (for the simple reason of making as much profit as possible!). Better from the passenger's point of view to have different versions for the mid-distance routes (London to Oxford, Bristol, Newbury, even Leeds) and long-distance routes, but of course we have to have things "standardised"... even if this means ordering totally different designs for each train order, and two types of IEP!

I doubt there are many people in Bedwyn wanting to go to Pewsey.
Thats not what I'm saying! I live 2 miles out of Marlborough and neither of those do I use as my railhead!

It's has to be better than using HSTs on semi-fast commuter services out of Paddington though.

Wheres the market for 4tph to Bristol? and more importantly, the paths!

By running 4 tph you may attact some people from the M4 and National Express coaches. Remember that the extra services will run via Badminton and it's possible a ten coach formation could run to Bristol Parkway where it would split with five coaches going to Cardiff and five going to Tempel Meads. There wouldn't be any extra paths required via Bath.

I believe it'll need 20mins of warming up before applying traction power. Brilliant :roll:

So if you have one of the engines running all the time under the wires then you only need to start the other two 20 minutes before you need them.

Is the demand for Cardiff really only 5 coaches worth? Especially with a reduced journey time.

Plus what happens on the reverse - both haves have to arrive into Parkway at the same time. A delay on one half will mean either that the two trains will have to travel separately onwards (paths!) or require a lot of slack at Parkway (platforms!).

Don't forget you will still have the Swansea service. There was a proposal to scrap the half hourly service back in 2006 at the start of the Greater Western frachise as the loadings west of Swindon were not considered to be high enough. It's possible that they will run 4 tph to Bristol Parkway via Badminton though, I'm just trying to see a reason for the dft's requirment for the trains to be able to split en route.

"only" need to start them 20mins in advance? There shouldnt be any need to do it at all - they should be all-electric, lighter, cheaper and dragged by a loco if needed; using modified Bi-mode Voyagers where absolutely neccesary; while saving money and improving the business case for extending the wires. It wouldnt be so bad, but apparently all IEP's will be 5-car, and Hitachi wouldnt engineer the bi-modes so they could remove become EMU's in due course.

Perhaps the worst thing about this travesty is 200 'semi-skilled' jobs, probably only lasting while the government subsidises the factory, will only be putting together flat-packs shipped over from Japan - while at the same time putting at risk much of the workforce at Derby should they not get the Thameslink order. Genius!
