Ice-free in winter owing to Ice Guard

Frost on the overhead lines can lead to serious timetable disruptions. Thanks to Ice Guard, ice formation does not stand a chance.

Daytime ice formation is not really a big problem, because the pantograph scrapes the accumulated ice layer from the overhead lines on each pass. However, ice and frost will get the opportunity to grow when fewer trains drive at night. The result: delays when trains start running again in the morning.


Ice and frost will partially stay attached to the overhead lines during the day, causing irregular conductivity. This creates sparks and ultimately causes the overhead lines to crack and split. In addition, the shower of sparks is harmful to rolling stock. Ice accumulation on top of the overhead lines can also cause power outage.
Many operators therefore opt to have an empty tram or train drive at night during periods of frost to keep the overhead lines free from ice and frost. A costly, time-consuming and wasteful undertaking.

"Train delays caused by ice and frost formation on the overhead lines will soon belong to the past"

The solution: spraying

Ice Guard is the solution to this problem. Treating the overhead lines with a special spray causes a thin layer to form on the lines that prevents condensation and water from adhering to the contact line. A special feature of this spray is that it needs not be applied every day. Each application protects the lines for a period of approximately 45 days. A few applications each winter therefore suffices.

Ice Guard keeps the railway free from ice

At the present time we still need to de-energise the overhead lines before treating. We are working on a new method for applying the spray even faster, while the lines continue to be electrically live, thus saving even more time.

Train delays caused by ice and frost formation on the overhead lines will soon belong to the past. Ice Guard keeps trains running, even during cold spells.
