A total of seventeen train cars, carrying over 3000 passengers, were wrecked.
It was the worst train accident in Pakistan in fifteen years.
The Quetta Express was stopped at Sarhad station because of a fault in the brakes when the Karachi Express travelling from Lahore to Karachi on the same line half an hour later and moving at about 120km/h (75mph), collided with it from behind.
[1] The collision caused at least three train cars to derail onto the opposite direction track, where they were subsequently hit by Tezgam, heading from Karachi to Rawalpindi.
[3][4] The exact number killed was not originally known; initial reports were of 109,[5] 120,[6] 127,[3] or more than 130 deaths,[2][4] with many critically injured.
