When will the Out of Service indication appear?

The Out of Service indication appears as the train approaches the station where service will end because this is a critical point in the operation of the train. The indication is meant to inform passengers and crew that the train will no longer be in service and that they should prepare to disembark. This provides essential timing for both the crew and passengers to ensure a smooth transition at the end of the journey.

By signaling this status as the train nears its final stop, it helps manage expectations and enhances safety protocols. It allows passengers to be ready for disembarkation and helps the crew to prepare for the next steps, such as securing the train or preparing for the return journey if applicable. This focus on passenger communication and operational efficiency is key in railway operations, emphasizing the importance of clarity and timing in signaling service statuses.
