A bit off topic I know, but I was astounded to see a display of when
the next bus was due in a bus shelter in Wandsworth.

The system is called Countdown, and about 2000 bus stops are equipped so
far (which leaves an awful lot still to go - I think only well-used
stops will be equipped).

London bus passengers have luxuries most of us can only dream about.

Of course, when Countdown goes wrong or displays the wrong times, or
doesn't display any time because some bus operators have not yet
equipped their vehicles, it can sometimes seem worse than no display at
all - but it does seem to be getting better at our local bus stop.
