When is the automated annoucements going to be updated to inform us Change
here for Overground @ Shepherds Bush on the Central line?

However long it takes them to record new messages, plus however long
it takes to update the data on each train. Could be months. I've never
known them to be in a particular hurry.

(eg The Jubilee Line was still advertising the Canning Town-City
Airport shuttle bus long after the DLR extension there opened)

Updating the trains seems to take years. I am sure that we are now
into years since they started replacing the "spank" announcements on
the Central and Northern, but many trains still have them.
