25kV AC is a lot more efficient than 750v DC - less energy is lost through heat (high voltage, lower current) - the justifications you listed above are used by Network Rail, I believe.
That's right, but if as the previous poster said, the cost of electicity is relatively low, when does it become worth the cost and disruption of making a changeover?25kV AC is a lot more efficient than 750v DC - less energy is lost through heat (high voltage, lower current) - the justifications you listed above are used by Network Rail, I believe.

RAGNARØKR;1255254 said:As I understand it, but I have not been able to find references, there are TSI regulations which come into effect in relation to railways running at 160kph and over. I recall being on a train from Hamburg to Cologne around 2006 which never went above 160 (there are speedos inside the carriages).
I believe the Germans require cab signalling over 160km/h - but that is a local rather then EU regulation...
The French are fine running 200km/h on normal signals

So I guess that the Class 221's that are spare will either have the Tilt removed and be given to Cross Country or placed on other routes like to Holyhead where they are still needed?
Just turning this thread back to the future of the Voyagers, now that according to the latest Modern Railways that E-Voyager has more or less been dropped, what does the future hold for the Voyagers?
If you look at any plans that either First or Virgin had, they both had plans to have baby Pendolino's take over the Birmingham - Scotland services.

I've tried to take this thread back on topic a couple of times, but it keeps veering off in weird and wonderful directions
First were planning on keeping the WC Voyagers, but use them for increased Bangor services, new services to Shrewsbury etc. Virgin claimed that they weren't keeping the Voyagers yet seemed to manage to plan to run lots of additional services by replacing 21 Voyagers with 21 short Pendolini.
I'd love to see them used on the XC core, which really needs capacity - rather than some of the fanciful ideas on this thread - simple, boring but necessary.

I have to agree with you there, however I know it is a bit of fantasy where the core routes are OHLE, but the Voyagers should be run as e-Voyagers and not just be a fanciful idea by Arriva for the Cross Country Voyagers.
Unfortunately, it comes down to cost though and a lot of re - wiring of the Voyager Units apparently which I seem to remember has been done on both Mk3 carriages for First and many other trains in the past to keep them in service.........
Quite. My thinking for a while has been that when/if any Voyagers are released from the WCML they be cascaded over to XC to double up services that are currently single Voyagers. Then once we're in a position to introduce EMUs on some XC routes those Voyagers rendered surplus could be used to expand the XC network putting places like Liverpool and Portsmouth (for example) back on the map.

Haha Brighton, that was my first encounter with a Voyager. Sexy looking train, I though, then it got on the move and, combined with the engine vibration, you could feel bumps in the track that I never knew existed after travelling almost daily for about 30 years on the route, those days mostly in CIGs and VEPs.And also Brighton, if paths are available!!
It will, the topic interacts with all sorts of other related issues and the decisions that have to be made around them. And the Voyager has always been a controversial train.I've tried to take this thread back on topic a couple of times, but it keeps veering off in weird and wonderful directions![]()
If this was to happen would there be any (no XC) routes that would be suitable for 3 coach 22x's? The one that I thought of was maybe the Cardiff/Portsmouth service.
Capacity is the problem. I'd imagine a 3 coach 22x will have similar capacity to a 2 coach 158 on a route that often sees 3 coach 158s.

Not just capacity, but also lack of comfort, means 22xs are a poor choice for regional express routes, the class 158 'Alphaline' units and 175s are much better suited to the task.That's precisely my concern. If you freed up some IC DMUs from the existing mainline routes, the obvious cascade destinations are the inter-regional "Alphaline" type routes, so Cardiff-Weymouth/Portsmouth/Crewe. They're long distance, unlikely to be electrified any time soon and could stand to have faster journey times. The problem of course is capacity, especially in the driving vehicles.
Give ICWC an all-Pendolino fleet (with drags beyond Crewe/Chester to North Wales) and XC can have longer Voyagers (and the Meridians once MML wiring is complete around 2022).

If a 22x is a poor choice for a regional express route, just what IS it a good choice for? It's better suited to Regional Express services than it is to current long distance services, thats for sure. They'd work pretty well on Cardiff to Portsmouth Harbour services in 4-5 car form, freeing up 158's for other regional long distance services.
A four coach Voyager wouldn't be (much of?) an increase in capacity compared to a three coach 158 - due to the low seating capacity in the end Voyager coaches (crumple zones, First Class seating etc).
So you'd be putting on longer trains with no extra seats where the 125mph capabilities are never going to be used.
That works for me, for routes such as Transpennine North and Manchester to Bournemouth if these trains are similar to the SWT class 444s (In having end doors and buffets, etc) and if they might be five carriage units rather than six in order to fit the limitations of some of the platforms on the routes that they are used on (Newcastle, Reading if required).But how about 6x23m flat front 110mph EMUs (maybe with gangways but that is likely unnecessary as doubling them would make them too long) for TPE and XC?
It is likely to be able to fit the same number of seats as a double Cl220 if it only has one disabled toilet and a Hull Trains 170 style compact buffet, which is all TPE XC is likely to need anyway.
That way you can convert all the soon to be electric XC trains out of Manchester to the South Coast and free enough Cl220s to retire the XC HSTs and double up more workings.
And it means you can replace all of the Cl185s on electric routes with them and end up with buckets of capacity....
Just a thought.
What on earth would you do with the comparatively small space between cab door and the furthest forward passenger door other than the present (useful) purpose that it is put to providing luggage space or storage for the trolley? You couldn't realistically fit any seats in there.Although if the 22x's were re geared to limit them to 100mph or possibly even 110mph which would enable the full use of the end coaches, which would overcome much of the capacity problem.

End doors are not going to be on any new non IEP stock at this rate.
The supposed advantages of them have been largely erased by the improvements in dwell times offered by the third position doors, improvements in door seals have largely removed any draft problems.
Mid-coach doors are for suburban commuter trains IMHO and should not be fitted to medium or long distance stock. End doors give a far better ambience in the passenger cabin and as a result improve passenger comfort.
Not that this appears to be a high priority issue, sadly.
