What defines the interlocking limits?

The interlocking limits specifically refer to the section of track that exists between opposing signals. It is a critical area where signals and switches are controlled to ensure the safe and efficient operation of trains. This defined zone helps maintain the orderly movement of trains, preventing collisions and ensuring that they can safely pass through junctions or intersections.

Understanding interlocking limits is essential for train conductors, as it affects how they manage the flow of rail traffic and coordinate with signal systems. The other options, while related to train operations, do not accurately describe this term. The distance between trains pertains to safe separation for operations, areas for inspection relate to maintenance activities, and the total number of trains indicates operational capacity, none of which define the concept of interlocking limits within railway operations.
