Which individual cannot copy a Track Authority on a moving locomotive?

The correct answer is that the engineer cannot copy a Track Authority on a moving locomotive. In railroad operations, the engineer is primarily responsible for controlling the locomotive and ensuring safe, efficient movement along the tracks.

When it comes to handling Track Authority, which is a critical piece of information used for train safety and operational control, procedures are established to ensure that communication and acknowledgment of authority are done safely. Generally, the dispatcher issues Track Authority, and it is the responsibility of crew members who are not actively engaged in the operation of the train to copy that authority to avoid distractions. Since the engineer is focused on the technical aspects of operating the train, it is against the protocols for them to copy Track Authority while in motion, as it could divert their attention from crucial driving tasks.

The other positions, such as the conductor and brakeman, are typically in roles that allow them to manage communications, including copying authority, ensuring that the overall operation remains safe and organized. The dispatcher, being situated in a non-moving location, also has the ability to provide instructions as needed without being in the midst of active train operations. This delineation of responsibilities is key to maintaining safety and efficiency in train operations.
