In the morning, there was added another strange chapter to the scandal of the aarhus light rail. Trains could not run because of ice on overhead lines.

This gave the sorely tried passengers the occasion to fear the frequent delays in the coming months, when Denmark freezer.
But the light rail director, Michael Borre calms.
– We have in Bergen in Norway have found inspiration for a good solution to the problem with ice on the overhead wires. From a special vehicle oil we glycol on the overhead wires, says the excited banechef.
Glycol is the means by which you also use to remove ice from aircraft wings.
It will in a viscous version to be applied from an amphibious vehicle – a small truck, which, from the tarmac roads can run out on the rails – in particular, it becomes relevant in the parts of the network, in which, owing to the absence of byvarme and buildings become very cold.
Via a specially designed pantograph (a device between the vehicle and the wires), lubricate the saw on the overhead, which is both deactivated and prevented against the ice cream.
Treatment lasts for two days and is considerably cheaper than the so-called iskørsler, explains Michael Borre.
Iskørsler is, where the empty train is running at night to keep the wires free of ice.
Michael Borre explains that there is no environmental impact by using Glycol.
