Does "track and time" authorize trains to occupy the main track within interlocking limits?

The concept of "track and time" does not authorize trains to occupy the main track within interlocking limits. The key aspect of track and time is that it provides permission for a train or other equipment to occupy a defined section of track for work purposes, typically outside of regular operational corridors. When it comes to main tracks within interlocking limits, additional rules and protocols are necessary to ensure safety and orderly train movement. Interlocking limits are areas where signals and switches are controlled to prevent conflicting movements, so entering these zones typically requires more stringent authorization and coordination than what track and time alone provides. This ensures that all trains can operate safely and efficiently in these critical areas of track.
