When a train reports clear of the main track, what information must be included?

When a train reports clear of the main track, it is essential to include the status of the main track switch. This information is critical for the safe and efficient operation of the railroad. Understanding the switch status helps maintain clear communication between the train crew and dispatchers or other railway personnel. Knowing whether the switch is set properly ensures that trains can operate safely on adjacent tracks without the risk of accidents or misrouting.

The other options, while they may be important in various contexts, do not specifically address the necessary information required for reporting clearance from the main track. For instance, while visual inspections and clearance times are relevant for operational safety, they are not as immediately crucial as the confirmation of the switch's status, which directly impacts the routing of other trains. Similarly, the train's new route may be important information but is not a requirement at the point when a train is reporting clear of the main track.
