Neil Williams:
It would also have been better if TfL had moved on from their
archaic insistence on the use of roller blinds, when the rest
of the country has moved onto the vastly superior LED technology...

Vastly?

Yes, an LED display is programmable and therefore wins on cost and
flexibility when it has to be changed. And multiple displays on
the same bus or train can all be made to change at once. But the
roller blind still wins hands down in terms of legibility, it seems
to me, and that's worth quite a bit.
