What term describes a track that is under the control of a Rail Traffic Controller?

The term "controlled track" specifically refers to segments of the railway system that are under the supervision and management of a Rail Traffic Controller. This designation implies that the operations on this track are regulated, including the movement of trains, signals, and any other activities that occur on it. The presence of a Rail Traffic Controller ensures safety and efficiency by coordinating train movements and responding to any incidents that may arise.

In contrast, non-controlled tracks are typically those that do not have active oversight from a traffic controller. Main tracks are the primary routes on a railway, while yard tracks are used primarily for sorting and storing trains. While all these terms relate to railway operations, they do not encompass the idea of direct control by a traffic authority, which is the defining characteristic of controlled tracks. Therefore, "controlled track" is the most accurate description of a track under the governance of a Rail Traffic Controller.
