Railway Minister Ashwini Vaishnaw on Sunday said that the tragic train accident in Odisha's Balasore occurred due to a "change in electronic interlocking".

Electronic interlocking is an arrangement of signal apparatus that prevents conflicting movements between trains through an arrangement of tracks. It is basically a safety measure to prevent signals from being changed in improper sequence. The aim of this system is that no train gets the signal to proceed unless the route is proven safe. Speaking to ANI, Ashwini Vaihsnaw said, "This is a different issue. It is about point machine, electronic interlocking. The change that occurred during electronic interlocking, the accident happened due to that. Whoever did it and how it happened will be found out after proper investigation."

He further said that restoration work is going on and normalcy will be restored before Wednesday morning.

"The commissioner of railway safety has investigated the matter and it won't be right for me to comment on that. Let the investigation report come. But the cause of the accident has been identified and the people responsible for it have been identified. Right now our focus is on restoration. There are two main lines and two loop lines. The work is underway and we will definitely complete restoration well before our target of Wednesday morning," Vaishnaw said.

The Railway Minister also refuted West Bengal Chief Minister Mamata Banerjee's allegation that the accident could have been averted with Kavach (anti-collision) device.

"It has nothing to do with Kavach. The reason is not what Mamata Banerjee said yesterday. She said as per understanding," he added.
