Which entity would most likely be impacted by delayed power restoration after an emergency?

Delayed power restoration after an emergency would significantly impact train schedules. Trains rely on a reliable power supply for operations, including signaling systems, station lighting, and train movements. When power is disrupted, it can lead to delays in train departures and arrivals, disrupt the flow of traffic on the tracks, and cause cancellations or adjustments in service to ensure safety.

Ensuring that trains operate on time is essential for maintaining service reliability and customer trust. If the power is not restored promptly, it can create a cascading effect on the overall schedule, resulting in further delays and operational challenges.

While local businesses, passenger comfort, and railroad expansion plans may also suffer from power outages, the direct and immediate effect on the operational schedules of trains makes this the most relevant choice in the context of the question.
