The 10.7 km long track with a gauge of 760 mm connects two locations of the Breitenau Magnesium Works, and daily freight transport takes place on it. The two endpoints of the line are Breitenau and Mixnitz. The mine and the grinding mill are located in Breitenau, in the narrow valley of the Breitenauer Creek, where building a standard gauge railway would have been too costly. The storage capacity at the grinding mill is also very limited. In Mixnitz, there used to be silos, but bulk transport no longer takes place; the goods are now transported on pallets and in big bags, with loading done by simple forklift trucks. The narrow-gauge railway could easily be replaced by trucks, but its maintenance is more environmentally motivated. Short-distance transport is carried out by trucks, but overseas shipments still rely on rail transport to the ports, with the narrow-gauge railway serving as a feeder. A daily 3-4 freight trains, each carrying 120 tons, would be a lot for road transport; moreover, the trains descend by gravity, requiring only braking, and the empty train going uphill has very low fuel consumption. Environmental protection, accident risk, and operating costs are all more favorable for the narrow-gauge railway. Therefore, the narrow-gauge railway is primarily an economic issue, but it is also significant from a PR perspective: the mining operation, by its nature, is destructive to the environment and does not wish to burden the surrounding roads with dangerous trucks that also cause more damage.
