It’s no secret that painting a subway line is the ultimate goal for most graffiti writers, and this is true worldwide. In fact, the “clean train” movement (named for the act of painting trains that are typically kept pristine) has exploded across Europe over the past several years, in countries like Poland, Italy, France, Germany, Switzerland, etc., and the access to European systems attracts travelling graffiti writers from all over.

Some transit systems do very little to stop graffiti writers, while others go to extremes, even shooting at vandals with pellet guns. In Sweden, they have come up with a new tactic, borrowing from the writers themselves: the conductors are allowed to carry their own paint (typically yellow) with them, and paint (read: scribble) over any graffiti they find on their cars!

Below, a conductor gets loose with it, followed by two examples of the “improved” cars:

Seems reasonable.
