Hi. I was one of the people who drew up the list of stops to have Countdown II. There were a lot of competing criteria (and some stops which everyone would want to have Countdown physically can't for reasons that aren't always obvious) but we'd got a list including removing from stops which had made sense when Countdown I was installed but no longer did and a handful where it wasn't clear why they'd ever got a sign (all boroughs were to see an increase in the number of signs). Then we received an edict from the Mayor that every stop with a Countdown sign was to keep it. He refused to speak to the head of our department about that.I've always thought that the choice of stop where Countdown was installed was a bit random. In my area, only one stop has Countdown, when it would be much more useful for other stops in the area, which have more routes passing through them
I spent a fortnight recalculating which stops would get Countdown II, knowing that the list I was producing was worse than the previous one.
The 2 stops which at the time (and possibly still) had the largest number of buses potentially calling did not have power and could not easily have power. 2 of the 10 busiest stops could not have them as they had narrow pavements, narrow bus shelters and assessors were concerned that people would back out into the road to see the sign clearly. One Countdown I sign was removed as it was being used by a local drug dealer to store his wares (causing intermittent faults every time the sign was opened with full power on).
