Green Cargo AB
Green Cargo is a sustainable logistics partner and crucial for Scandinavia’s trade and industry. We are rooted in the origins of Swedish rail traffic and we are Sweden’s most experienced operator in rail logistics. Round the clock, our freight trains transport raw materials from forests and mines to the process industries, and consumer goods to the retail sector.
Green Cargo is owned by the Swedish State. We transport 21 million tonnes of freight, have 1,800 employees and annual sales of about SEK 4 billion (2020).
Electric trains make up over 95 percent of our ton kilometrage, meaning the climate impact is next to zero. Every 24 hours, some 400 freight trains depart, replacing 8,500 truckloads on the road network. We serve close to 300 locations in Sweden, Norway and Denmark through our network, and with our partners we reach all of Europe. Our efforts are not only about a comprehensive reduction of carbon dioxide emissions, but also about space efficiency and safer roads.

The maintenance procedure for railway brake discs is highly complicated, time-consuming and costly. Firstly, the entire wheelset is separated from the wagon and then the bearings and the wheels are separated from the axle followed by the brake discs. For this reason, brake discs are preferably changed at the same time as the wheels. This procedure involves a risk of damaging the wheels and the axle during removal and reinstallation. The axle might develop scuffs or scratches, leading to replacement of the entire axle. Such incidents cause increased life cycle costs of these wagons. A segmented brake disc can prov
