Half the uk’s population live within this circle (note, quite a lot of it is sea). It’s probably right that half the money is spent there too..
So how much of that sweet, sweet ‘Southeast’ money gets thrown at Birmingham, Leicester, Peterborough, Northampton, Norwich etc?
Here’s a starter for one.
Whilst the government is tripping over itself to throw money at London-centric transport projects, the funding for electrifying the Midland Mainline (which runs through a fair bit of that circle) was cancelled. Its now going only as far as Corby and Market Harborough, failing to reach the 9th, 10th and 13th most populace areas in the UK (Nottingham, Sheffield and Leicester Urban Areas).
So whilst London benefits from the Midland Mainline electrification at the Thameslink end the rest of it has the prospect of 44 year old diesel trains being used for the foreseeable future and having to have their ‘fast’ services held up by (Thameslink) commuter trains as they’re being given priority.
