What is the acceptable speed for trains after being notified of bridge issues?

In situations involving bridge issues, it is crucial for train operators to adhere to a restricted speed. This means that trains must travel at a speed that allows them to stop within the distance they can see clearly ahead. The reason for this requirement is to ensure safety while assessing the bridge's condition and responding to any potential hazards that may arise. By maintaining a restricted speed, operators can react appropriately to visual cues, such as obstacles, and can take immediate action if a problem is detected.

Other speed options, such as very slow or moderate speeds, do not provide the proper protocol that addresses the specific situation involving potential infrastructure risks. Normal operational speeds could lead to dangerous situations, as they do not allow for the necessary caution needed around compromised structures. Therefore, adhering to a restricted speed is essential for ensuring safety during bridge inspection and response to issues.
