I was on a North/Eastbound Circle or District from Notting Hill Gate to
Paddington on Thursday. As we approached bayswater, there was an
announcment "The next station is Bayswater", followed by "This train will
not stop at the next station".

The eastbound has been closed for a while and is sealed off with high
corrugated barriers just behind the yellow line.

According to thetube.com it is due to re-open on tuesday and the westbound
will be subject to closure until the end of the month. Not sure what's going
on, "refurbishment" it says. I guess doing it this way they can complete
quicker rather than being restricted to engineering hours, and station users
can still travel, albeit by using the west / changing either side.

Cheers,
Dave
