NAUSHAHRO FEROZE, Dec 20: The Pakistan Railways said on Thursday that while investigation was still under way, sabotage did not appear to be the cause of derailment of the Karachi Express which, according to the revised figures, killed at least 40 people and injured 249 others on Wednesday night.

An FIR lodged by the guard of the train and statements of some officials and passengers initially indicated that a fault in rail track might have caused the accident.

“The real cause has not been ascertained yet,” said Pakistan Railways’ operations manager Junaid Qureshi.

The FIR has been lodged under Sections 337-G, 320, 427 of the PPC and Section 129 of the Railways Act. The police told Dawn that guard Ghulam Shabbir Chandio had stated in the FIR that the accident had taken place due to the train’s jerk.

The train driver told police that the train was running at normal speed of 105-kph when the accident took place.
