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.

I've never seen these printed notices, I've heard the statement over the tannoy never seen a printed notice.


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

I've yet to see those sort.


Just to run this past you again.

They use electricity to power up an indicator board,

and this indicator board does it just conatin info for 1 line or 1 train or 1 service ?


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

Not seen them either.


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 ?

Because you might what to know what is running, for instance at Mile End the hammersmith line might be out but NOT the district line and they share the same notice board. The fact that the next train might only go half way or it might go the whole journey is more useful than a blank notice board which will tell you nothing.



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..

When reported I find it useful. What I don't find useful is notice boards with NOTHING on them.


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.

But it could also be right.




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.

Blind passengers can't read notices that say this indicator board might be wrong, either.
