• Breakthrough in the fight against “track slip”

  Track slip caused by leaves on the track costs SEK 100 million annually, according to a study by the National Rail Administration. A solution to the problem, which according KTH researchers is most prevalent in the Stockholm area around late October/November, is however close to hand. The origin of this slipperiness caused by leaves falling on the tracks is unclear, and intensive research is now being conducted on how it can be most easily detected and best eradicated.
