What is indicated if the station dwell time reading is yellow?

A yellow station dwell time reading indicates that the train needs to remain at the station longer. This signal typically serves as a cautionary measure, alerting the train engineer that the scheduled dwell time has not yet been reached or that there are factors delaying the train's departure.

In rail operations, dwell time can be influenced by various factors, such as passenger boarding and alighting, operational delays, or safety requirements. A yellow reading suggests an ongoing need for the train to remain stationary, ensuring that passengers can complete their boarding or disembarking safely, or addressing any operational considerations before the train proceeds.

Understanding this aspect of dwell time is crucial for maintaining safety and operational efficiency in train services.
