Why does the train stop when it rains heavily? The reason why the train stopped when it rained.

1. Rainstorm affects line safety: In rainstorm weather, when the rainfall reaches a certain value, lines and equipment will be flooded. At the same time, after the subgrade and surrounding rock and soil are saturated with water, landslides, mudslides and other disasters may occur, which will affect the driving safety. At this time, the train needs to run at a speed limit. In severe cases, the railway department should block the section, and the normal operation of the train can only be resumed after the maintenance personnel check and confirm the safety of the line.

2. Foreign objects affect the safety of power supply: both EMUs and electric locomotives need electric drive, and it is the railway catenary equipment above the rails that provides safe power supply for Wan Li railway line. When branches, plastic bags and other foreign objects beside the railway line float on the catenary equipment due to wind and rain, the train will be forced to stop, and the train can continue to run after the foreign objects are removed.

3. Rainstorm affects the driver's sight: Because the train runs fast, rain will seriously affect the driver's sight in case of rainstorm. When the driver's sight distance is lower than the specified value, the train needs to slow down to ensure driving safety.
