Any sign of these being used yet?

I saw a report elsewhere that a couple of dozen were supposed to have been
brought into use yesterday...

The barriers on the high numbered platforms have been in use for
around a fortnight.

It was never intended that the Oyster reader yellow roundels would
work immediately. They will follow once all the gates are in
operation. The gates on the overbridge are some weeks away still.

Are there any plans to install gates at the top of platforms 15/16, to
separate tube from national rail platforms?
