What should workers ensure when one or more trains are authorized to move at high speeds on adjacent tracks?

When trains are authorized to move at high speeds on adjacent tracks, it is crucial for workers to prioritize their safety. Stopping work and moving to the predetermined place of safety (PPS) is the correct course of action for several reasons. High-speed trains can create significant wind gusts and noise, which may pose hazards to workers in close proximity to the tracks. Additionally, the risk of a train encountering a worker is greatly heightened at high speeds, making awareness of one's surroundings critical.

By having predetermined places of safety, workers can quickly and efficiently relocate in a manner that minimizes the chance of injury. These safety protocols are designed to protect personnel from unexpected incidents that could occur when trains are operating at elevated speeds. Ensuring that all workers understand and follow these safety measures is vital in maintaining a safe working environment near railway operations.
