Weed-free railways: Alternatives to Glyphosate

Specialized trains accelerating to 50 km/h and spraying herbicides directly on to the tracks is currently the cheapest and most widespread measure to keep railroad tracks free of plant growth. However, the negative ecological consequences of Glyphosate require a new approach. The task of the IZT is to develop an effective alternative vegetation management system for European trains. Three potential alternatives are emerging: first, we want to work on using small amounts of organic acids. Second, we want to consider killing off the plants with focused hot water jets. This method is already being used in municipal vegetation management. Third, "electro weeding", a practice from organic farming, may be transferred to the vegetation control of trains. Here, electrical fields are used to kill off the plants.
