 A train in Pakistan has smashed into derailed carriages of another train, killing at least 36 people. Authorities say it is the latest accident to highlight the decrepit state of the railway system that dates to the 19th century. Railway officials, several passengers, were still trapped in the mangled cultures strung across the tracks in the southern province of Sindh. Train crash in Pakistan on Monday has killed at least 36 people, according to government officials, in the latest accident to highlight the hazardous state of the country's over a 165-year-old railway system. The death toll was likely to rise as rescuers struggle to reach people trapped in mangled compartments scattered across the tracks in the southern province of Sindh. Every helicopter flew overhead to carry the wounded passengers. A Pakistan railway spokesman said several carriages of one train fell across the adjacent track after a derailment in the Ghotki district. A second train, coming from the other direction, then smashed into them. Prime Minister Imran Khan said on Twitter he was shocked by the horrific accident and was ordering a comprehensive investigation into railway safety. Accidents on the decrepit system are common. In 2005, in the same district, about 130 people were killed when a crowded passenger train rammed into another at a station and a third train hit the wreckage.
