Where will the train dispatcher register the time comparison?

The time comparison is registered on the train sheet because this document is used to track the movement and progress of trains along a specific route. The train sheet typically includes vital information such as scheduled times, actual departure and arrival times, and any delays. By recording the time comparison on the train sheet, the dispatcher can effectively assess train performance, maintain safety, and ensure efficient operations. This is essential for coordination and communication about train movements with other operational staff.

In contrast, while the log book is important for recording various operational details, it is not specifically tailored for time comparisons related to train schedules. The dispatch receipt serves as a confirmation of communication between the dispatcher and train crews but is not focused on time performance. Lastly, the communication record captures conversations and instructions but does not primarily emphasize time tracking as the train sheet does.
