But I believe action will be taken one day, and once again a largely
graffiti and vandalism-free railway will return.

I'm inclined to believe this, but I wonder what the 'tipping point' will be
that will force the hand of the various railway stakeholders? I feel
vandalism couldn't get a lot worse 'south of the river', but I worry that
the thugs will turn to random (and endemic) attacks/muggings of passengers
and staff before any action is taken to restore order. What the 'answer' is,
I haven't a clue.
