What characterizes the interlocking limits?

Interlocking limits are defined as the physical boundaries that govern the operation of signals and switches in a rail system. This area is specifically characterized by the tracks that lie between the most distant opposing signals. These signals play a critical role in ensuring safe train movements by providing indications to train operators, and the interlocking system coordinates the movement of trains through these tracks to prevent conflicts.

The area within the interlocking limits is designed for the management of train traffic and to facilitate the safe and efficient movement of trains through complex junctions or intersections. It incorporates not just the signals, but also any switches or other track components necessary for track routing.

Understanding this concept is vital for ensuring the safety and efficiency of train operations, as the proper functioning of signals within these interlocking limits significantly affects train movement and safety protocols.
