Effort needs to be put into driving down the costs - I notice there was a thread on that subject lately. Other countries produce both urban and rural railways for a fraction of th costs of the UK. What exactly is the point of the the so-called National College for Advanced Transport and Infrastructure if not for training British engineers in best practice both domestic and overseas.
It's not the actual engineering/building of things where the cost increases occur, it's the overly exacting, complex, slow, public sector procurement processes, & this expensive obsession with accounting for every penny of public expenditure. (We will spend £1 to account for 50p)
Because the processes take so long (years & years & years) then you have to deal with inflation, & the shiny new stuff that gets chucked in by politicians.
Then every few years you have to get the consultants in to check the workings on stuff that was correct when it was originally written 5 years before.
Have you ever looked at the costs of getting something done on the highway, like a zebra crossing?
"Zebra crossing (including high friction surfacing on approaches) typically costs between £21,500-£34,000.
(Costs quoted are approximate and do not include fees involved with the design and implementation of the scheme or the cost of any legal procedures involved unless stated.)"
Yet we already employ, & pay, the council officers who are doing the design etc works, so why are they being charged for again?
Now, back to the Eastern leg.
For the Eastern leg to get the go ahead, then the first phases need to be seen to be a success. So those in the area need to be positive about the first phases, so that they can then say to the politicians 'HS2 works, we would also like it'.
If all you do is put it down, then it's easier for the politicians to turn around & say 'why would you want something that doesn't work?'
