What frustrates me is that there seems to be no joined up thinking.
FGW want 4/5 car trains
XC Need more than 4/5 car trains
GWR wants four-coach trains that can carry about 300 people, which is what a four-car, all standard class HST would shift - and that's with the low-density seating layout. Even if you converted a 220's first class coach to standard, you'd struggle to get many more than 220 seats in them.
The general consensus is around 15 years from the time they're modified with power doors and return to service. That takes you to around 2034 (end CP8) with the possibility of maybe managing through to 2039 (end CP9) depending on diagrammed mileages and ultimately their reliability.
Chiltern reckoned that on the basis of taking a long hard look at the bodyshells of their Mk3s during the power door work back in 2012 that they were good for about 20 more years, so I would tend expect the mid-2030s is really the outer limit of their potential lifespan.
It depends from whose perspective you are looking at it. All things considered, there is no satisfactory solution to the problem of running services above 110mph which have unequal loadings along the route. You can either:
- use portion working, or make passengers change to a shorter train, which is satisfactory for railway operators but not passengers, or
- you run a long train throughout and accept the light loadings over part of the route, which is satisfactory for passengers but not railway operators
Obviously, you have decided that it is more important for the solution to be satisfactory for operators, personally I would rather the solution was satisfactory for passengers, hence our disagreement.
I'm a passenger too and somehow, for my entire life, I have somehow coped with this terrible imposition on passengers, such as first generation dmus splitting and joining at places like Shrewsbury and Machynlleth, Turbos at Oxford, blah, blah, blah.
Give passengers the right information - when they book, on the platform and on the train - and they aren't all as dumb as you seem to think they are.
A modest number of passengers may be in the 'wrong' set ahead of a split, but when trains split, the front set doesn't usually take off like a scalded cat the instant the couplers part. Railway staff are, amazingly enough, also alert to the need to tell people what's going on and help them make the switch. And if you have large/heavy bags, it is usually a lot easier to get off a train and walk down the platform than try to struggle down a train through narrow gangways.
Some may ignore all efforts to tell them what's going on and end up going in the wrong direction but that can just as easily happen on services formed of sets with corridor connections.
By the way, it is the passengers who have to foot the bill for running around all the empty coaches you seem to find so 'satisfactory' - passengers might find a more cost-effective way of operating, which keeps down costs and their fares, a more satisfactory option for their bank balances.
Not pointless because the 5-car new trains could presumably be used on Cardiff/Bristol-Plymouth/Penzance services instead of the short IC125s, instead of on services out of Paddington.
Eh? What are you on about?
