Winds halt train times

Since spring, many parts of the country have experienced a wave of windy days.

During the May Day holiday, strong winds even affected trains.

On May 1, strong gales in Baoding, Hebei province, caused a foreign object to be caught in high-speed rail overhead lines, leading to the delay of trains.

Some passengers were even stuck on their trains mid-travel.

High-speed trains are powered by electricity, and they receive power from overhead wires strung along the overhead lines, according to Worldwide Rails, a rail news website.

As an important part of the power source for high-speed trains, why are rail overhead lines so fragile in face of wind?

The overhead line equipment itself has strong stability, but there are too many light objects floating along the line.

"These foreign objects are extremely dynamic and difficult to control. After all, except for some tunnel sections, the railway is an open-air environment," He Changlin, deputy head of the Catenary Technology Section of the Beijing Power Supply Section, told Beijing Daily.

Kite wires with a metal core are one of the troublemakers that haunt railway workers every year.
