Just like train graffiti in Odense the train graffiti in Copenhagen has risen. DSB spent 9 million DKR more in 2009 on the cleaning of trains than in 2008.
Last year in 2009 DSB spent 25 million DKR on cleaning 2177 train cars.
In the 10 first weeks of 2010 the rise can still be seen. To combat this they are proposing to begin video surveillance of their yards.
