What is required at highway grade crossings equipped with automatic warnings during an ABS failure?

At highway grade crossings equipped with automatic warnings, in the event of an Automatic Block Signal (ABS) failure, it is necessary for trains to stop and provide on-ground warning unless otherwise instructed. This requirement is in place to enhance safety at crossings where the usual automated warning systems cannot be relied upon due to the failure. By stopping, train crews can ensure that the crossing is clear of vehicles and pedestrians and can communicate effectively with any potential hazards.

This protocol prioritizes safety by providing an opportunity to assess the situation and prevent accidents that could occur from going through a crossing without functioning warning systems. It mitigates risks associated with the unpredictability of highway traffic and ensures that all necessary precautions are taken to protect life and property.
