To add to what starmill has said, having visited on 8th June and again on 13th, the area is also now significantly more landscaped with a number of plants now in the non accessible areas with woodchip covering the area. Quite how they have managed to get the screen going with completely the wrong time goodness only knows, but when I went through yesterday (14th) it was the same, just now displaying a time nearer to 20:00!
Someone on Friday evening did ask if that was the right time - maybe they were hoping that the first train of the day to Whitby wasn't too far away :P
It seems the whole place is still run off some generators (can hear them from the footpath over the other side of the bridge which we walked along from Marton) - hopefully they will get it mains wired at some point soon.
I was slightly concerned to find that, whilst tapping around on the TPE TVM at Middlesbrough, that inputting "James" gets you James Street (Liverpool) and nothing else, so unless it is under a different name, tickets cannot be bought from TVM's to it. I tried a Northern machine at Morpeth too, to the same effect - not good on any count!
Middlesbrough also didn't use the automated announcement system for the Whitby service (whilst it was in use for a Saltburn and Bishop Auckland service around the same time), opting instead for a manual override - so maybe the system are not yet programmed for it and to avoid blanks, they have just stopped them altogether.
