- "Wet-rail" syndrome (water mixed with oxides) accounts for 50% of Autumn train low-adhesion incidents. Replicating the phenomenon in the laboratory has, until now, not been achieved. This paper, co-authored with Virtual Vehicle Research in Austria, details the development of a new technique for studying wheel/rail interface friction that allowed close control of oxide/water mixtures and achieved low friction. A unique friction model that clearly pin-points the small range of conditions over which the effect exists was also developed. Both are now being used in Siemens(Austria) and Rail Safety and Standards Board projects focused on friction enhancement (contact: Vehicle/Infrastructure Interface Engineer).
