A pile of spoil has appeared in the car park where the station is going, I imagine they're digging it up? I'll try and get a picture tomorrow.
Other than that, nothing visible has happened on the site (although of course that doesn't mean nothing has actually happened!).
One thing I've noticed is that the site is lit up at night by two diesel powered portable floodlight units. Apart from making a fair bit of noise (canal boat chugging along at full throttle, with added rattly washers, I'm sure you've heard it before!), it does seem a bit pointless given that nothing is happening overnight, and the neighbouring road (Vincent Drive) is lit up. I suppose it's to discourage theft?* The generators are also pumping out visible emissions (although I'm a fan of the smell myself!), which should surely be discouraged in a built up environment. What makes it worse is that the carpark already had "mains powered" floodlights, but these have been turned off. Although I suppose the lampposts and wiring may interfere with the construction work.
*Not very effectively: as I was walking past about half an hour ago, there was a group of 3 girls maybe 50m in front. One of them nipped across the road by the entrance to the site, but then was spooked by the light being on in the "site office" (small container with two tiny toilets and an adjoining room). Instead, a traffic cone was liberated from the NHS blood donation place car park next door. The group also had a road sign with them. I wonder why traffic cones, road signs (and shopping trolleys!) are specifically not permitted in the university accommodation contracts...
And where did this group end up? That's right, university accommodation...
As promised, here are some pictures.
Nothing much appears to be going on at the southern end of the site:
There is evidence of work going on here...
Including a pile of stone to the left of the roller
And a wooden fence being installed:
