The mishap occurred on Jalapur Road in Lodhran town when the three-wheeler rickshaw carrying 11 schoolchildren tried to cross an ungated railway line ahead of an incoming Karachi-bound train.
The driver of the rickshaw also died in the accident, local police official Sardar Ali told PTI.
"The ages of six killed school children were between 6 to 10 years," he said.
The Hazara Express was going from Lahore to Karachi when it hit the rickshaw carrying around 11 children in addition to the driver and another passenger, police said.
Railway Minister Khawaja Saad Rafique told reporters that the exact cause of the mishap will be ascertained after proper probe which has been ordered.
"We have to investigate whether it's negligence or if it happened due to heavy fog in the area at the time of the accident," Rafique said.
Heart-wrenching scenes were observed when the dead bodies of the children belonging to one extended family were carried to the residence, police said.
About 20 people were killed when a train crashed into stationary coaches in Karachi in November.
