Will the railway be blocked by ice on snowy days?

Generally, it will not affect trains, unless it is a rare snowstorm that will affect the normal transportation of railways.

First, because the heavy snow will accumulate on the turnout and frog, it will directly affect the train passing through the turnout to a certain extent, and even make the train have problems, causing traffic accidents; In addition, the switch machinery will be frozen, which will make the line unable to be arranged and lead to the interruption of railway transportation. Therefore, whenever it snows heavily, the station will organize the transportation and electric power departments to clean it;

The second heavy snow will cover the line, make the track circuit bad, make the signal display wrong or not, easily cause the locomotive signal to stop without code, and even cause train conflicts;

Thirdly, mainly on electrified railways, snow disaster will cause the electric catenary to break and collapse, thus making the electric locomotive unable to run;

Fourth, it affects the driver's outlook. Although the current locomotives have locomotive signals and monitors, the safety of driving has been greatly guaranteed, but in bad weather, accidents are prone to occur, so trains slow down in snowstorms.

Therefore, on the northeast railway trunk line, there is an automatic electrothermal snow removal device on the turnout, which can effectively guarantee railway transportation.
