This painting was created to mark the opening of the ‘Kettenreaktion’ project in the disused Attisholz industrial complex in the Solothurn region. The BTS association, which until then had been organizing graffiti and hip-hop events in the Solothurn region, was commissioned to create murals in the rebuilt space and occupy part of it.

The painting takes a humorous approach to the activity of graffiti artists on trains, personifying the carriages, appalled to see the graffiti artist approaching in the shadows while the police car is fast asleep.
