What is the biggest hazard on the track?

The biggest hazard on the track is the trolley wire. This overhead electrical wire supplies power to the trains and poses a significant threat, particularly due to the danger of electrocution. Workers or individuals in proximity to the tracks must be cautious to avoid contact with the trolley wire, as it operates at high voltage. Furthermore, the presence of trolley wires often requires additional safety protocols, such as maintaining a safe distance and ensuring proper training for all personnel around the tracks.

In contrast, while loose gravel, inadequate lighting, and heavy machinery are certainly hazards in a mining environment, they do not carry the same immediate and severe risk of injury or fatality as electrocution from the trolley wire. For example, loose gravel may cause slips or falls, inadequate lighting can result in visibility issues that lead to accidents, and heavy machinery poses risks during operations. However, the electrical hazards from the trolley wire represent a more critical and potentially life-threatening issue, which makes it the biggest hazard on the track.
