National News // Aug. 1, 2018

Swiss Federal Railways says the heatwave is causing some lines to buckle as the rails expand. Speed limits have been imposed on some lines around Zürich and canton Aargau.

Some lines are being cooled by using fire trains, which pour water on the tracks.

One train company, the Rhaetian Railway in Graubünden, is experimenting with painting the lines white to reflect the heat. It’s a trick sometimes used in Italy. It’s thought the move could lower the track temperatures by 7 degrees.
