The East Sea Subway Dispatch Center is a semi-circular hall of approximately 180 degrees, with each subway line having three tiers of monitoring stations.
In this nearly one-thousand-square-meter subway dispatch center, the most prominent object was undoubtedly the large LED screen, about ten meters long and four meters wide, at the front.
At that moment, real-time power control conditions of the subway line are displayed on the LED screen.
"Hey, is it almost shift change time? Ah, I can finally rest."
The dispatch center was divided into four shifts, each with seven staff members, to ensure round-the-clock monitoring. Every shift lasts six hours.
The two workers responsible for traffic dispatching had been working intensely for almost six hours, and were understandably tired.
"Beep, Beep, Beep…"
Suddenly, a series of hurried alarm sounds came from the dispatch command system.
"What happened?"
The seven people in the hall all turned their attention to the LED screen.
