Will heavy rain have any impact on the high-speed rail?

Heavy rain has an impact on the safety of high-speed rail operations. It is not uncommon to hear that high-speed trains and high-speed rails are subject to speed restrictions or suspensions due to weather conditions. The train suspension is related to the heavy rain weather encountered in the country; weather processes such as lightning and strong winds also often bring challenges to the normal operation of the trains. Rain will not cause EMU trains to be suspended. EMU trains will only be suspended during severe weather such as thunderstorms and strong winds that may cause damage to railway facilities and equipment.

Compared with aviation, waterway, and highway transportation, railway transportation is indeed least affected by weather. However, to ensure the safety of high-speed trains and high-speed trains, weather factors cannot be ignored.

Disastrous weather such as strong winds, thunder and lightning, heavy rains and floods, hail, snow, heavy fog, as well as extreme high and low temperatures may have an impact on the operation of high-speed railways, high-speed trains and their roadbeds, bridges, power grids and other facilities.

Even if the railway tracks and tunnels have a set of drainage devices, when the short-term rain is too strong, the heavy rain may wash away the roadbed; thunderstorm activities may cause train and railway communication and signal failures, posing great hidden dangers. ; Under high temperature conditions in summer, the longitudinal pressure on the rails increases. If timely measures are not taken, an overturning accident on the track may occur when high-speed trains pass by.

Geological disasters caused by disastrous weather processes, collapse of roads and bridges, damage and collapse of facilities on both sides of the railway, may all affect railway transportation.
