I'm not sure when this started happening, but trains were running round

been updated.

I flew back from Bucharest on Sunday 17th and trains were running
around the loop then, as the press release said, but the diagrams in
the trains still showed the replacement bus service. London Transport
is usually pretty efficient about changing the in-train signage for
closures and openings, so this must have been a rare slip-up.
