On 7 June 2021, before dawn, two trains collided near Daharki, in the Ghotki District of the southern province of Sindh in Pakistan, killing at least 65 people and injuring about 150 others. An express train derailed onto the opposite track, and a second express train crashed into the first roughly a minute later. About six to eight bogies were left "completely destroyed".
Locals rushed to the scene to rescue survivors, hindered by the darkness. The Pakistan Army, paramilitary Pakistan Rangers, an urban search and rescue team, helicopters, and accident relief trains later joined in the rescue efforts. An official investigation was ordered to establish the cause of the crash. An initial investigation report determined that the initial derailment had been caused by the failure of a welding joint.
The train's signal system was poorly maintained, and much of its tracks were in a state of disrepair. Due to corruption and mismanagement, the railway system sees frequent accidents, and a lack of investment exacerbates issues. Although a number of governments have pledged to clean up the system, none have succeeded in doing so thus far.
