When a frog point is broken out more than specified dimensions, what must be done?

The correct answer highlights the need for reassessing the maximum speed when a frog point is broken out beyond specified dimensions. This is crucial for ensuring the safety and stability of train operations. A frog point, which is the area of a track where trains switch from one track to another, must maintain strict dimensional integrity. If these dimensions are exceeded, it can affect the performance and safety of trains traversing that section.

Reassessing the maximum speed involves evaluating whether it remains safe for trains to operate at their usual speeds or if adjustments are necessary to prevent derailments or other accidents. This step is critical in maintaining not only infrastructure integrity but also overall operational safety on the railway.

In this context, notifying an inspector, suspending train operations, or indicating that a maintenance report is not required might all be plausible actions; however, they do not address the immediate need to determine the safe maximum speed given the broken dimensions. It's essential to prioritize a thorough risk assessment first to maintain safety standards in train operations when infrastructure issues arise.
