How are catenary poles primarily identified?

Catenary poles are primarily identified using a unique Catenary Pole Number, which allows for precise tracking and management of the infrastructure along the rail line. Each pole is assigned an individual number that facilitates maintenance, inspections, and operational planning, ensuring that conductors and maintenance staff can quickly identify and reference specific poles when needed.

This systematic numbering is crucial for safety and efficiency, as it provides a clear and standardized way to communicate about infrastructure among various teams, including engineering and operations. Knowing the specific pole number helps in organizing the maintenance schedules and tracking work performed on the poles, ensuring that any issues can be swiftly addressed.

In contrast, while timetable locations, distance from passenger stations, and distance from interlockings may provide supplementary information about where poles are located relative to the service, they do not serve as the primary identification method for the catenary poles themselves. Thus, these other options lack the specificity and operational efficiency that the Catenary Pole Number offers.
