Copenhagen Trains : Vandal Tactics is a recently released film documenting the trains of Copenhagen’s transport system and the graffiti work that has appeared on them. The film covers (in the main) the work that was completed over a 10 year period between 1997-2007, see an example below from Cres & Cave, photo taken from Cold Crush.
At almost an hour long, it is quite clearly a pretty comprehensive piece of work, featuring footage of train painting in action. Check it out here;
