[5][6] It was revealed that the onboard train attendant followed company procedures to contact the control center about the crane obstructing the track.

[7] However, the control center at Taichung Metro would require 20 seconds to activate the emergency brakes remotely, which was insufficient to prevent the collision.

[8] At a press conference, Taichung Metro revealed that based on CCTV footage of the train and the station before the fallen crane, the following events occurred:[7][9] Taichung Metro said they intended to seek at least TWD 0.2 billion (USD6.5 million) in compensation against Highwealth Construction Corp for damage and losses resulting from the collapse.

[11] Taipei Metro admitted that the existing procedures regarding driverless trains, such as the Wenhu Line, were inadequate to stop the train in time under a similar scenario as the track circuit would not be broken and detect a fallen crane, and staff opening the manual driving panel or informing the control centre to cut off power would have taken too long.

[12] The Taiwan Transportation Safety Board concluded in June 2024 that the primary reasons for the collapse were a failure to ensure proper operation of a tower crane and a lack of clear measures for restricting or prohibiting construction on either side of Taichung Metro tracks.
