The train derailment in eastern India that killed more than 300 people and injured hundreds more was caused by an error in the electronic signaling system that led a train to wrongly change tracks, India’s railways minister said Sunday. The train entered another line, known as the loop line, and crashed into a goods train parked there, PTI said. In 1995, two trains collided near New Delhi, killing 358 people in one of the worst train accidents in India. In 2016, a passenger train slid off the tracks between the cities of Indore and Patna, killing 146 people. Most train accidents in India are blamed on human error or outdated signaling equipment.
