What is the purpose of blue signal protection?

The purpose of blue signal protection is to ensure safety during maintenance operations. This safety measure is crucial when workmen are on or near the track, as it helps to prevent train movement in that area, significantly reducing the risk of accidents. Blue signals are placed to signal to train crews that work is being conducted before a train can enter the work zone, providing a clear visual indication that the track is not safe for trains to occupy. This protocol is vital in protecting the lives of workers and ensuring that operations can proceed without the threat of unforeseen train movements. The focus on safety is paramount in railroad operations, making this protective measure a critical aspect of maintaining a secure working environment in potentially hazardous conditions.
