At the same time, they quickly coordinated a transfer arrangement for all passengers on the G1218 train, ensuring that these passengers could continue their journeys unaffected while the train underwent a thorough inspection.
Meanwhile, the railway police department almost immediately began to mobilize all available surveillance cameras along the route, as well as the train's own surveillance footage.
They checked the recordings of the G1218 train during the time period from Shucheng to Xi'an Station earlier that day.
They reviewed all available surveillance videos, including cameras installed at intervals along the railway tracks, at the front and rear of the train, and at every station platform the train stopped at, trying to track any clues that might be related to the incident.
Police personnel began examining each frame of the footage, looking for any unusual behavior or suspicious individuals, especially near the various stations the train had passed through.
