Thank you Michael - that is absolutely fascinating, especially the mention of the underpass lift access and the PV side improvements.

However, the main crossing does not get a mention in this section of the framework. (There might be more info in section 4.3.5.)

There is an artist's impression though, showing our barrier-less island and people waiting to cross, but there does not seem to be any pedestrian signalling at all at this point!
I think I'm meant to be ogling at the concept of the new station and plaza rather than crossing details.
