2021 Hualien train derailment

On 2 April 2021, at 09:28 NST (01:28 UTC), a Taroko Express train operated by the Taiwan Railways Administration (TRA) derailed at the north entrance of Qingshui Tunnel in Heren Section, Xiulin Township, Hualien County, Taiwan, killing 49 people and injuring at least 200 others. At the time of the accident, the train was carrying 494 passengers. The eight-carriage train derailed after colliding with a construction truck that had fallen down a slope onto the tracks north of Hualien City; the train came to rest in the tunnel, with severe damage and many casualties. The train incident was primarily due to human factors and was preventable, as an investigation from The New York Times revealed that it was "systemic failures at a government agency" including "a culture of complacency and weak oversight", that had made the disaster possible.

The accident is the deadliest train crash and second-deadliest rail accident in Taiwan, surpassed only by a train fire in 1948 which may have killed up to 64 people.
