Turkey Street station is being rebuilt... or maybe built is more
appropriate. But about a month ago, when they had built the roof and
installed glass in about a third of the structure, they stopped and have
not progressed since. I doubt that it's weather related.. Does anyone
know what's happening?

Since it's been an Overground station for a while now, I presume it's
manned the whole time, but prior to the completion I can't see where the
staff would be, apart from shivering all day in the open. (I haven't
been there in the hours when it's open.)
