A couple of times over the last few days I've seen a blue plus symbol printed out to fill an A4 sheet of paper and stuck on the inside of the windscreen in the cab, facing out towards the direction of travel.
This is on 379s on the Stansted Express route.
What does it signify?
Curiosity will get the better of me one day...
Thanks!
