When will a Station Overrun indication appear on the TOD?

A Station Overrun indication appears on the Train Operator Display (TOD) when a train misses a station that it is designated to stop at. This situation is critical because it can lead to safety issues, such as passengers being left at the station or delays in the train schedule. The TOD is designed to provide real-time information to the train operator, including alerts for operational anomalies.

In this context, if a train bypasses a scheduled stop, the system detects this deviation and triggers the Station Overrun indication. This alerts the operator to the fact that the train has not adhered to its stopping schedule. It's important for the operator to be aware of this in order to ensure proper communication with the passengers and to maintain safety protocols.

The other choices represent scenarios that do not inherently relate to the criteria for triggering a Station Overrun indication: a train stopping at all scheduled stations does not involve any missed stops, scheduled inspections are routine checks unrelated to operational status, and authorizations by the operator would typically relate to operational changes rather than indicators triggered by missed stops.
