It does have a "Next fastest train to..." display, but Clapham

Yes - it's extremely stupid that it doesn't have CJ on it.

Actually, with these boards, I wonder whether they just work on the
timetable data or whether they account for delays to departing trains.
Personally I wouldn't expect them to be clever enough...



The ones on SET at places like Lewisham certainly don't cope. They
will tell you that the next train to London Bridge is coming at
whatever time the next scheduled train is likely to eventually turn up,
regardless of whether several undelayed ones might be going there
sooner. Even to the extent of showing that the next train to London
Bridge is cancelled, which doesn't really help with when the next one
is.

So it seems to work out when the next scheduled train is and then
simply repeat its expected time or cancelled status, with no reference
to any other trains coming sooner.

Shame - you'd think it would be easy enough to take the number of
minutes delayed, add it to the calculated London Bridge arrival time,
and then work out which train is fastest using that...
