How London centric can you be? Strange how people in Manchester and Birmingham are supposedly major beneficiaries because they can get to London quicker but people in London don't benefit from getting to Birmingham or Manchester quicker. Getting somewhere a bit quicker isn't everything or even the most important thing. It removes long distance services from existing routes thereby increasing paths available for more services from the Home Counties into London. It's a London project. As I said it does have some incidental benefits for the North but it is a project that mainly benefits London and the South East.
Creating extra platforms in Manchester, Leeds and Birmingham (OK they were/are due long distance services only, but that didn't stop local services from using then) benefits the South East how exactly, especially given that they also could have been made to be useful to the full NPR scheme (further removing long distance services from the existing platforms)?
Yes this does full in a lot of the gaps in what's happening with the existing network which could have been filled in, however much like there's a lot of scepticism about what's happening in 2040, the same way have been true about 2030 of it was announced 10 years ago.
Also whilst a lot of the headlines were about London to Northern City stations there had also been some information about journey time improvements between Birmingham and those cities and between cities in the Eastern arm if people looked for them.
My overall view of this is:
We're building the first bits of HS2, but to appease those opposed to HS2 we've cancelled the Eastern Arm.
We're still looking at how we can get HS services to Leeds (including keeping the HS2 route as an option by protecting it, but shhh don't tell stopHS2).
We've raised that we need to keep doing what we're doing with improvements to the existing rail network, so here's some electrification of lines were should have done years ago.
We've realised that HS2 cut off XC services from connecting to it so have fixed that.
Overall there's still plenty of scope for more things to be added, including a lot of detail. Likely to be announced at times which suit us politically.
