Great Western franchise to be broken up?

Chiltern were looking to not terminate at OOC^▸ (Old Oak Common (depot)) (lack of platform space likely) but return towards their route via the freight(?) branch to the east of OOC, thus using OOC as a circular route back towards Ruislips. (Does that make sense? I know what I mean, just not the names of the lines invloved)

It sounds from those quotes as if the HS2^▸ (The next High Speed line(s)) plans are being altered even at this late stage; it's only a lean-to to the headhouse at Greenford that was the problem.

I take that back, having checked the drawing. The headhouse at Greenford is, as I said, clear of the NNML tracks. The larger outline sticking out and overlapping the tracks is the shaft, and shown as underground. So it must be an expansion of the shaft into a cavern at tunnel level. Vivat the NNML!

The shaft after construction will be capped off, the access for intervention purposes and service will be quite small in comparison therefore a line can be "bridged" over the top
