What are the effects of thunderstorm weather on Qinghai-Tibet railway in Qinghai-Tibet Plateau?

When the Qinghai-Tibet Railway was built in the special geographical terrain and geological structure environment of the Qinghai-Tibet Plateau, the plateau thunderstorm was an extreme weather that did great harm to it. In the plain area, due to the mature defensive measures, the harm of thunderstorms can be avoided to some extent; However, in plateau areas with high altitude and relatively low clouds, the harm of thunderstorms to ground facilities and electronic facilities is far greater than that in plains. The Qinghai-Tibet Railway is a high-incidence area of plateau thunderstorms, especially the Wudaoliang-Lhasa railway section, which is three to five times higher than that of Wuhan and Shanghai at the same latitude. Naqu area in the middle of the plateau is the area with the highest frequency. According to statistics, the frequency of thunderstorms along the route is much higher than that in coastal areas of China. Especially in July and August in summer, there are a large number of plateau thunderstorms along the Qinghai-Tibet Railway, which easily affects the operational safety of the railway. ?
