What does "track and time" including the words "switch yes" signify?

The phrase "track and time" in conjunction with "switch yes" signifies the inclusion of track between absolute signals. In railroad operations, particularly in managing train movements, "track and time" refers to the authorization granted to a train or work crew to occupy a specific segment of track for a specified duration. This is crucial for ensuring safety and coordination among different trains using the same track.

When "switch yes" is appended, it indicates that the switch is aligned for the intended route, meaning the track is clear and ready for the train to proceed. Therefore, this scenario involves ensuring that the track section indicated in the authorization aligns with the necessary safety protocols, affirming that the track is between absolute signals, which is pivotal for maintaining a safe movement of trains and avoiding collisions.

Understanding this terminology is vital for personnel in train operations as it encompasses both the movement authority and the operational readiness of the track infrastructure.
