What kind of point is referred to for track warrant limits?

Track warrant limits are referred to using identifiable points such as switches. This method ensures clarity and safety in operations, as these points are easily recognized by train crews and signal maintainers. Identifiable points provide a clear and consistent reference for crews to understand the extent of their authority to operate within, which is crucial for the safe management of train movements.

Using identifiable points minimizes ambiguity, as it is vital for all personnel involved to have a common understanding of the limits. This can prevent potential misunderstandings and operational errors. In contrast, vague concepts like informal landmarks, arbitrary distances, or virtual waypoints may create confusion due to their lack of clarity or specificity, which is why identifiable points are preferred for establishing track warrant limits.
