They added that they initially rescued passengers on a self-help basis from the bogies and that rescue teams arrived at the scene of the accident till not much later.Video footage from earlier in the day showed the heavily damaged train engine and carriages, as emergency workers and local people used metal-cutting tools and heavy cranes.

Pakistan Army also took part in the rescue efforts. Prime Minister Imran Khan issued a statement of condolence in which he blamed the infrastructure of Pakistan’s colonial-era railway network which has fallen into disrepair due to chronic under-investment and poor maintenance. “Have asked Railways Minister to take emergency steps to counter decades of neglect of railway infrastructure and ensure safety standards,” Khan tweeted.Minister for Railways Sheikh Rashid also expressed grief over the loss of precious lives caused by the accident.
