Death lurks - plane or train

Maybe not the most pleasing headline, but please read this.

A digital info board at a Light Rail crossing near the Humphrey Terminal in Minneapolis flashes 'Security threat level Orange' on the morning of the foiled terror plot in London. Normally, this board displays the day's high and low temperatures, seat belt reminders, and the names of new airlines landing at and taking off from Humphrey.

Perhaps this board is doing two jobs at once - reminding citizens of the security threat associated with plane or train.
