I’m not convinced a parent who didn’t notice the pram rolling towards a moving train, and who hadn’t strapped the child in, is going to notice an extra sign… Hopefully this lucky escape will be enough of a wake-up call :/.

It’s like the number of kids who get left in the back of cars (most dangerously in hot climates) led to dashboard warnings to check the rear seats. These work for a week or so, and then also just become wallpaper.
