Deutsche Bahn (DB) has painted around 1km of the track on the Hanover and Würzburg high-speed line with environmentally friendly white paint to see whether it could prevent the serious problem of overheating rails and warped tracks during heatwaves.
The Rhaetian Railwayexternal link in the eastern Swiss canton of Graubünden is testing a technique commonly used in Italy to fight the distorting effects of heat on metal: painting the tracks white.
The goal is to keep the metal tracks from deforming or buckling in the heat, which has affected the whole country in one of the hottest Julys on record.
The white coating is currently being tested on a 300-metre (984-foot) section of track in Graubünden, between the villages of Küblis and Fideris. The paint was applied in mid-June, just in time to exert its effects in the full summer heat.
In theory, the temperature of the tracks could be reduced by as much as seven degrees as a result of the treatment, Yvonne Dünser, a spokesperson for the Rhaetian Railway, told the Swiss News Agency, ATS. The results will be assessed when it is less warm. Rail research A study by the Swiss Federal Technology Institute ETH Zurich showed that white paint had a positive impact in strong sunlight. The researchers then turned to the Rhaetian Railway as a practical test subject.
