High-tech devices make holiday travel more comfortable

5. Snow-melting device

Snow-melting devices have been installed at turnouts from Maoxian railway station to Zhenjiangguan railway station, a section of the Sichuan-Qinghai railway, formerly known as Chengdu-Lanzhou railway. The device can switch functions in light of snow accumulation and temperature, to ensure the safety of train operation. When the temperature drops below 0 C, its heating units start working.
