The Green Line train was moving through the elevated corridor south of Feng-le Park station when the crane boom fell from the thirty-first floor of a Highwealth Construction Corp building site beside the tracks. The impact was sudden and catastrophic. At least one witness, a Canadian passenger on board, later said the driverless train was stationary when the crane struck — and that it then proceeded forward, colliding with the debris already lying across the track.

The onboard attendant followed procedure: contact the control center, report the obstruction, wait for guidance. But half the control center staff were on meal break at the time. The train had no automatic mechanism capable of detecting a fallen crane on the tracks. The gap between what the system could sense and what had actually happened proved fatal. The legal scholar was ejected from the carriage upon impact; she was then struck by the train itself. Fifteen other passengers sustained injuries in total.

In the days after the accident, her colleagues and students described her as a spirited advocate — someone who had devoted years to legal education and the slow, unglamorous work of building civic knowledge. She was 52. She had boarded a routine commuter train on an ordinary Wednesday morning.

Her name was not widely published in international coverage, but in Taiwan she was mourned as a person of substance, not simply as a casualty. The legal community held her in high regard. Her death gave the public tragedy its human weight, a reminder that behind every statistic is a life in full.

The Taiwan Transportation Safety Board's formal inquiry identified several compounding failures. The track circuit system — designed to detect trains, not fallen objects — could not register the crane boom on the rails. Procedures for driverless trains like those on the Green Line did not include a fast enough path to emergency stop: staff would have needed to either obstruct the doors manually to prevent departure, or locate and use a separate manual driving panel, both of which required more time than the forty-one seconds available.

Taipei Metro, which operates a similar driverless line, acknowledged that its own procedures shared the same vulnerability. Across Taiwan, metro operators began reviewing construction sites adjacent to their tracks. The accident exposed a gap that had gone unexamined precisely because nothing like it had happened before — at least not in an urban MRT context.

In August 2024, prosecutors indicted two workers on charges of negligent manslaughter. The legal process that followed was careful and deliberate — courts were asked to weigh individual responsibility within a system that had not adequately protected anyone.

Taichung MRT proposed concrete procedural changes: a standardized emergency hand signal for staff, encouragement for passengers to obstruct closing doors as a last-resort stop measure, and the relocation of manual driving panel keys to more accessible positions. The agency also committed to upgrading obstruction detection equipment at stations. The acting chairman of Taichung MRT resigned days after the accident. These reforms did not undo what had happened, but they reduced the likelihood that the same chain of failures could repeat.

Taichung is a city in motion — its skyline punctuated by construction cranes, its street grid expanding faster than any single agency can fully monitor. The MRT Green Line represents the transit ambition of a growing metropolitan area, threading together neighborhoods that were once hard to reach. That ambition and that construction activity will coexist for years to come.

The accident near Feng-le Park station did not stop that growth. It did force a harder look at the spaces where construction and transit share the same air — the zones above tracks where a crane can reach, and where the consequences of a structural failure arrive faster than any procedure can respond.
