Thanks. Someone must have thrown the wrong switch somewhere affecting the
display at Bayswater.

I don't know for sure, but my guess would be that the message you described
is programmed into the system (1980s software, don't forget), and is so
difficult to change that noone has bothered. Either that, or noone realised
that the change in service patterns required a change in the software for
the describers.

A similar example occurred on the Northern Line in 1999, when the line was
closed between Moorgate and Kennington for several months for engineering
work. The DMIs at (at least) Euston and King's Cross continued to show the
message "all trains go to london bridge".
