Fair enough. It's a fact that the WCML has had vastly more money spent on it in recent times than either the North & South Transpennine or the Calder Valley lines have.
That may just possibly have something to do with there being vastly more people who use the WCML every day than use the Transpennine or Calder Valley lines.
Why is an already comically expensive high-speed rail link from a regional capital to the national capital needed in addition to the fast rail links that already exist, and how will it help to rebalance regional economies? What evidence is there that these existing rail links have helped the economies of Darlington and Doncaster to develop in a way comparable to London? I'm not saying we should get rid of the existing rail links; I'm saying if we're serious about rebalancing regional economies and improving the transport infrastructure in those areas, let's spend some serious money predominantly in those areas, instead of always prioritising London and connections thereto. Not everyone starting in Birmingham, Manchester and Leeds wants to go to London. Large numbers of them want to go to Leeds, Manchester and Birmingham. But because those places aren't London, they don't seem to matter. I'm not the only one who's tired of it.
Several issues in there. Firstly, you seem to be arguing as if the
only purpose in building railways is to re-balance the economy. It isn't. We build railways in order to achieve many different outcomes. Balancing the economy better is one useful outcome. Others are to make it easier for people to get to where the jobs are, to get cars off the road, to reduce pollution and congestion, to enable more mobility, etc. etc. And also - importantly - to attract enough new custom to pay for itself. You need to consider how railway investment impacts all of those. I would
suspect (without knowing any calculations) that HS2 wouldn't do as much to rebalance the economy as say NPR on its own (if that were possible) would do, but because it frees up so much capacity along very well used and overcrowded routes, will do far more £ for £ for all the other aims.
Secondly, you seem to be implying that there hasn't been much rail investment in the North. Maybe you're unaware of the vast expansion in Manchester Metrolink recently, or of the extensive electrification in the Manchester/Liverpool/Blackpool area. Or of the new train fleets that both Northern and TPE are in the process of introducing. Or of the significant frequency increases that are happening across much of the Northern network (some of them postponed until later this year because of the timetable meltdown last May). Or of the new links that have been/are being built to run services Liverpool-Runcorn-Chester and Manchester-Burnley-Blackburn. Or of the electrification of the Chase line. Or of this little thing called Northern Powerhouse Rail that is being worked on (and which is likely to depend on HS2). Of course, there are good arguments for doing a lot more than that, but making out that places that are not London don't seem to matter for rail investment is just miles away from reality.
Thirdly, you also seem to have missed that HS2 will - once phase 2b is built - enable much faster and more frequent journeys between cities in the North/Midlands. Birmingham-Leeds for example is likely to go from a 2-hour journey to less than 1 hour. Sheffield-Leeds and Manchester-Birmingham are also likely to become much quicker, while the new line into Manchester will take pressure off the overcrowded Manchester-Stockport corridor.
