I’ve now had a more detailed look at the line of route ‘virtually’, to get a better idea of the challenges to be overcome were this project to be taken forward to the next stage. I should have done this years ago.
This would be a big, big job. Much of the formation and main civils has gone. That which hasn’t would almost certainly need to be replaced. And there’s a lot of it. Then there’s some all new elements required, for example flood defences (the line of route has clearly washed away in places, or in danger of doing so); to get over / under roads that were formerly level crossings; to get over / under the ‘new’ A66 at least twice. Then there’s a lot of ‘new’ property on the line of route, and with much open country around it is likely to be necessary to build a route that avoids it, even if that is more expensive, which it almost certainly will be. The scale of works required is bigger on a per mile basis than, say, East West Rail.
It’s almost certainly going to be over £30m / mile in cash prices, and probably nearer £40m. So £500m-£700m.
No one with any intelligence can possibly argue that this would be the best way to spend this sum of public money on transport, or even anything, in the Lake District.
