But if it "may" not be correct what's the point of having it at
all ? Why not just switch it off until its fixed ?

A reasonable Q , but maybe they don't know it's incorrect until passengers tell them
;-)

But they already know the indicator boards "may" be incorrect. Thats why they put
up *Printed Notices* to that affect.

Printed Notices mark you, not ad-hoc notices scribbled in marker.

Just to run this past you again.

They use electricity to power up an indicator board,

They have also printed notices which say " The information on the
indicator board may not be correct.

So what's the point of powering up the indicator boards if there's no way
of knowing whether the information is correct or not ?

The reason, as with the bus and train announcements is that its all done
for the sake of appearence; rather than because its of any practical use.

A station platform with a nice indicator board with bright orange lettering on it
looks *nicer* than one with the lettering switched off. The fact that the information
is maybe wrong is purely secondary.


sometimes you get a bus that is not from the area and it announces stops that arent
where it;s stopping.

See above re. platform indicator boards.



if you
insist they could be switched on and off as blind people boarded and
alighteed from the bus -

Is that just the audio or the rotating message display too ?

the visual displays aren't annoying; and in any case your question borders on the
absurd when asked in respect of blind passengers.
