I wonder if Eye readers might have chanced on this natty little graduate brochure from NR.
If you turn to page 13, you will see a nice picture of a most unusual set of wigwag lights.
Could this be a new standard pioneered by one of NR's recent trainees and now being rolled out nationally?
If so, perhaps it accounts for some of the crossing abuse that we see so much of these days.
Perhaps time NR had a quiet word with the graphic designers.
