Walking past Alexandra Palace station this afternoon, I noticed that
the standalone Oyster reader (on the pavement, next to the outdoor
ticket machine) has had its neoprene jacket removed, and was inviting
passengers to touch in or out of the station, and had an orange LED
lit.

I can't see any mention on the TfL or First Capital Connect website
that PAYG is now valid from this station - does the working reader
mean that it probably is, but they've just not told anyone about it
yet?

(I'd have tried it out for myself, but was on my way to the park...)
