Appreciate that this thread may only get a few replies, but I was struggling to fit it in to one of the already existing threads so was left with no choice but to create a new thread entirely.

In essence, they've been fiddling around with the destination displays. Again.

This time it seems to be to make the route-varying letter smaller (see here: https://flic.kr/p/2kw3c9k). I've seen a couple of other photos this evening of a couple of 1As of which both had the smaller number so they must be seriously considering rolling this out.

What's the theory behind this one? Is there a small glimmer of evidence that suggests that passengers may find it easier to read the *full* route number when displayed in this way?
