India train disaster: Signal fault the likely cause, minister says

Key Facts

Media caption, The BBC's Archana Shukla in Cuttack: ''Distress and chaos'' at the hospital treating the train crash injured India's railway minister has suggested a signal fault led to the Odisha rail disaster, with a "change in electronic interlocking" the likely cause.
The crash saw a passenger train collide with a stationary goods train and derail, after being wrongly directed onto a loop track by the side of the main line.
At a press conference on Sunday, Jaya Verma Sinha from India's Railway Board said both passenger trains had approached a Balasore district station under a green signal - indicating it was safe - within seconds of each other at the correct speed of under 130kph (81mph).
She said the passenger trains had been supposed to pass each other on the main lines but the Coromandel Express rammed into an iron ore-laden freight train on the loop line, causing the engine and some coaches to lift over the top of the heavy goods carriages.
