Can we confirm whether this new West Coast Partnership will still have Network Rail in control of signalling and infrastructure?
As I recall mentioned in some rail rags particularly a few years ago that the DFTs plan is to trial giving operation of signalling and infrastructure management to some TOCs in the future, possibly on the East Coast to begin with in the next franchise on that route.
These are 2 different things.
HS2 is not NR infrastructure (nor is HS1).
However NR signal and maintain HS1 under contract to its owners (as they do for the Heathrow branch).
While eventual ownership, control and regulation for HS2 hasn't been determined I expect it will follow a similar model, with NR doing the practical work.
Separately, the government wants private money into NR, particularly for new projects.
The aim was for the newly-autonomous Routes to put up projects that could be funded externally, somewhat like the way Crossrail was funded in London.
Like HS1, they want the huge funds of pension schemes used to capitalise national infrastructure.
None of that has been confirmed, and it's still early days for the NR Routes.
The WCP model combines the operator for the WCML and HS2, but nothing has really been said about the nature of the partnership as far as infrastructure is concerned.
Given that HS2 Ltd will be buying the rolling stock rather than WCP, it doesn't look like a deep partnership to me.
The ECP model is supposed to generate a single management team for the route, but I doubt the TOC will have any day to day control of infrastructure.
They may well influence upgrade priorities though, and share the business case (investment/return).
I doubt DfT has thought it all through yet - meanwhile the roof is falling in on the current operation.
