What does a "Section" refer to in rail terminology?

In rail terminology, a "Section" specifically refers to a portion of rail track between two yard limits. This definition highlights the importance of yard limits as boundaries that help define the operational area of rail traffic. A section is crucial for maintaining safe train movements, as it allows for efficient communication about the location and status of trains within that defined area. By understanding sections, rail workers can ensure proper signaling and coordination, contributing to overall safety and efficiency in rail operations.

The other options do not accurately encapsulate the definition of a "Section." For instance, while a section of track within city limits might refer to a specific geographical area, it does not convey the technical boundaries of yard limits. Similarly, the servicing area for trains or the signals used during rail operations serve different purposes and meanings within railway operations, further distinguishing them from the concept of a section.
