Two trains collided in western India early Thursday killing at least 22 and injuring more than 100 passengers, local media reports said. The Sabarmati passenger express crashed into a stationary goods train in Samalia in western Gujarat state's Vadodra district at around 3 a.m. (2200 GMT) when most of the passengers were asleep. Seven carriages of the express derailed and rescuers were using steel cutters and cranes to remove the debris of mangled coaches and check for trapped survivors. More than 100 passengers were injured, some with fractured limbs and deep cuts, while a majority had abrasions and bruises. The driver and assistant of the passenger train were killed. Indian Railways Minister Laloo Prasad Yadav said the cause of the accident could be human error or faulty signals, the PTI news agency reported. The Sabarmati express was on its way from the northern pilgrim town of Varanasi to Ahmedabad city in Gujarat.
