there's NO point in 9cars going all the way to PNZ
Perhaps not, but I'm sure some posters have said the IC125s do get well used in summer, so would a 5-car unit be sufficient, ALL THE TIME? I personally doubt it.
In lots of respects I consider brand new trains a must now. We can't keep on refurbishing 35-40 year old stock. New trains with a 30+ year lifespan are what's needed. Not Trigger's Broom.
The trouble is the brand-new trains being offered have alot of problems associated with them, such as:
- Underfloor diesel engines, both a discomfort to passengers and potentially an excuse to keep burning diesel and defer electrification for another 30 odd years rather than, at most, 20yrs if we keep IC125s
- Shorter sets, fewer seats, no buffets and thus potentially no hot food for standard class passengers
- Non-gangwayed multiple working and possible portion working (yuck)
- 26m vehicles, meaning they would be unable to operate some services where the GW▸ franchise's trains currently provide vital extra capacity
So yes, new trains would be nice, but let's have some more electrification first and a design with buffets, at least the 8 carriages currently provided and 23m vehicles that can fit on the whole GW
INTERCITY network.
I'm also a fan of a progressive forward looking rail network, looking to address capacity and meeting the needs and aspirations of all users.
I hope my list above makes clear that my objections are based on areas where I beleive the new trains would not meet "the needs and aspirations" of certain rail users. I'm even being forward-looking (see electrification).
Very simplified - I'm guessing many will be 2x5car to PLY» , splitting there.
To which I say 'please no'. Portion working without
UEGs▸ is something akin to the devil's own work in my book.
I know what I'm about to say is not very fashionable these days, but fashions tend to go in cycles. If a train is 5 + 5, what's to stop 5 cars being detached for another destination on the way? There are statistics out there that say between 40% and 46% of traffic is lost if you make a change of trains necessary along the way, so (looking at the positive) perhaps there's some possibiities?
Fashion has nothing to do with it (in my eyes anyway). I agree with what you are saying about removing the need to change trains, portion working is done day in day out at Machynlleth with class 158s between Birmingham and Aberystwyth/Pwllheli and I think it is a great idea. The difference is class 158s have UEGs, and (generally) helpful guards, so if you board the wrong portion you can correct your mistake. On a train without UEGs you cannot, in which case (assuming you have a helpful guard informing you of your mistake) you basically have to change trains anyway to move to the correct portion.
There's another thing about 158s as well, they are 2-car units. With shorter sets, it is easier to balance the capacity allocated to each route (153s are, in theroy at least, even better in this regard). While I don't know (for sure) of anywhere it is done at the moment, it is plausable to have a 6-car formation with 2 coaches detaching for one destination and the other 4 continuing elsewhere. With the 800/801/AT300 fleets, it is a choice of 5-car, 10-car or 9-car. So, using your example, you have to have 5-car for both Paignton and Penzance even if, for example (I have no idea of actual demand), Penzance trains need to be load 7 and Paignton only 3-car. The 125mph crumple zones and (first-class only) kitchens waste a heck of a lot of space in a 10-car pair of 800s too, just one more seat than a fixed-formation 9-car 801.
I say again, portion working is great for short
DMUs▸ with UEGs, but for 125/140mph
INTERCITY trains it is just plain silly. Just work out how to provide a robust DMU connection without leaving passengers waiting ages on a wet, windswept, platform.
(UEGs = Unit-End Gangways)
