Where should trolley wire be located in relation to the rail?

The correct positioning of trolley wire is crucial for the safety and efficiency of operations around the rail. When trolley wire is located at least 6 inches outside the track gauge on one side, it minimizes the risk of accidental contact with the train or workers on the rail, reducing the potential for electrical hazards. This distance provides a clear separation between the power source (the trolley wire) and the moving trains, which is vital for maintaining safe operations in a mining environment.

Additionally, this arrangement allows for easier access and maintenance of both the trolley system and the rail itself. Having the trolley wire outside the track gauge ensures that it does not interfere with the wheels of the train or any other equipment that may be operating on the rails.

In contrast, positioning the wire directly above the rail or inside the track gauge can lead to dangerous situations where the trolley wire could come into contact with the train or workers, increasing the risk of electrocution or accidents. A position that is at least 12 inches below the rail fails to align with operational standards, as it may not provide adequate clearance for safety and may complicate maintenance activities. Thus, maintaining the trolley wire at least 6 inches outside the track gauge on one side is the most effective approach to ensuring safety
