Iron ore train slowdown in Narvik
Up to 68 wagons loaded with iron ore are to be braked downhill. Each wagon is equipped with a brake mechanism and the heavy sparkling noise can be heard over large parts of the city, in some places dominant and in others as an atmospheric spice. The sound is a powerful story about trains, iron, industry, and the heart of the region. The target for the train is the major port of Narvik from where the ore is to be shipped.

A wide green boardwalk dominates Kungsgatan in Malmö. This is an example of how broader transit routes might look if you choose to deprioritize traffic in future cities. A greener city provides many benefits, including acoustical ones, since it brings out the local and more relevant sounds.
