As I recall, the TPE issue was stated to be that the track/signalling enhancements were not fully coordinated with electrification works. This may have been untrue, but I believe it was stated.
I've no problem with that approach - same at Oxford - it's frustrating that we have a railway where one hand wanted to wire a route/station whilst the other hand wanted to remodel it rather than planning these things together in the first place though.
Co-ordinating these things should have been the procedure from day one.
And again I said a while back that bi-modes gave a perfect excuse to delay electrification indefinitely which is exactly what we have right now. If they had ordered EMU's you can bet they would have got on top of it. Instead of getting on top of it they have converted more IEP's to bi-modes and now deferred a lot of it. But because of the fact they ordered bi-modes there is no PR consequence! With bi-modes they can defer/cancel/delay electrification at will
Plenty of schemes have been delayed/ descoped/ ditched in recent years.
MML electrification, TPE electrification, Electric Spine, East West...
Most of these would have required "pure" EMU operation (if they were going ahead), yet they have been delayed/ descoped/ ditched.
They didn't "get on top of it" - they pulled the plug/ kicked the schemes onto the CP6 wish list.
If the commitment to bi-modes on the GWML had meant that it was so easy to cancel, with no PR consequences, then wouldn't they have cancelled GWML electrification first (whilst focussing resources on the pure electric MML etc)?
Bi-mode trains are the reason why yesterday's news isn't the end of the project - the only positive to take from the story - yet you are blaming bi-modes (whilst seemingly not noticing all of the other projects that were delayed/ descoped/ ditched, projects which didn't commit to bi-modes).
Also the other plan was to remove the extra engines from some of the 800's when electrification had finished and there was less need to have the full diesel capability on all trains
We should be thankful that the flexibility of bi-mode trains means that we can order more diesel engines to get through the NR delays (and then remove them at a later date if/when they become superfluous).
Great trains.
Not really the GW electrification project was planned to cover the core Thames valley, GWML and SWML routes only.
This would still have left golden valley, cotswold lines and Worcester-Bristol routes untouched all of which do see multiple daily HST services, golden valley is 1 per 2 hours, cotswold's ditto and Worcester-Bristol are peak time extensions of golden valley.
All of these would have in a pure EMU option needed a pure DMU ordering or loco's to haul the EMU's, some stations are short platformed so loco hauling with the EMU actually making platform in any meaningful way would be interesting.
Actually bi-modes incentivise continuation as finances are available rather than big bang total route modernisation.
The times four/five cost increase for a descoped GW electrification is kind of point where had the plan been pure EMU DfT would have long since gone back to the train builders to exercise whatever break clauses exist and kill the project, I suspect the 2015 review would have straight cancelled a pure EMU GW project. It would today be cheaper just about to cancel the project write off the current work as sunk cost to run DMU only IEP's, back in '15 even more so
Agreed - both re the flexible bi-mode trains allowing Hereford etc to retain their existing services (something which others haven't provided an alternative "solution" for) - and the fact that a "pure electric" GWML would probably not have seen any wiring beyond Crossrail's Reading extension - we'd now be debating whether to squeeze several more years out of HSTs or terminate a number of services at Reading instead.
The monumental cluster**** that is GW electrification will probably set back any rolling programme of electrification by a generation or more.
Had NR been able to deliver the vision and cost per single track km forecast for GW with claims of further reductions possible overtime then we would be looking at a rolling extension programme to address the bits of GW not planned and on to the XC network
Agreed - sadly.
We may be frothing about "what if the GWML had worked as planned and we'd gone on to make a positive case for wiring other routes in western England" in a generation's time - this feels like such a wasted opportunity.
Can't see the Marlow branch ever being knitted unless some company comes up with a viable 2 car AC unit or the branch goes over to using trams
We may need such a unit on other lines too (I appreciate that Cardiff Bay may not get wired any time soon, but there are a number of services in line for electrification that won't need anything like a 3x20m EMU).
The Government assumed (& told the TOC, apparently) that the money was coming out of the depot and stabling fund part of the CP5 settlement. NR thought otherwise.
So the DfT signed up to a franchise deal that had all these extra units being on Exeter each night without ensuring, through their wholly owned infrastructure subsidiary (NR), that the depot would be there in time to deal with them.
You couldn't make it up.
This isn't helping belief in a "nationalised" railway being able to solve things very easily (beyond the mentality of some enthusiasts who think that it'd mean The Government handing over bucketloads of cash every five years to some Proper Railwaymen and not interfering - which certainly wouldn't be the way that any politicians would treat a 21st century railway)
