What is the primary function of the Train Operation Display (TOD) when leaving a station?

The primary function of the Train Operation Display (TOD) when leaving a station is to indicate system status and commands. This vital information helps train engineers understand the operational parameters of the train and the status of the train system in real-time. The TOD displays crucial data such as speed, track conditions, and any commands or alerts pertinent to the train's operations.

By providing information about the system status, the TOD ensures that the train engineer can make informed decisions to safely and efficiently operate the train. This functionality is essential for maintaining safety and adherence to operational protocols, especially during critical phases such as departing from a station, where situational awareness is key.

Other options, while they might seem relevant, do not encompass the primary role of the TOD. For example, live video feeds, monitoring other train movements, or providing weather updates do not directly pertain to the immediate operational needs of the train engineer as they prepare to leave a station. Instead, the TOD focuses on system diagnostics and command execution, which are fundamental to ensuring safe departures and maintaining efficient train operations.
