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".

Er, what's the problem with changing 1980s software? At least if it's
software, it *can* be readily changed, as distinct from firmware or
hardware.

It's firmware. The controllers for the DMI look rather like a teletype!

Um, changing software often isn't as easy as you make out. In principle,
it's entirely malleable, but in practice, it's often incredibly difficult.

Yes, I know, I was doing it before you were born; but I can't imagine that
disabling one particular message would be all that difficult (though
regenerating it in firmware could pose problems with old kit).
