The apex court asked them to study measures adopted last year by Karnataka government that helped in minimising the casualty of tuskers.
It turned down the plea of Railways to modify its December 10, 2013 order asking to take steps to reduce speed of trains while travelling through forests inhabited by elephants.
The court had also proposed to change rail routes passing through forests and to discontinue the movement of goods trains at night in certain sections where such accidents have been witnessed.
"The MoEF and Railways will examine all these aspects and submit their detailed suggestions and steps they are going to take so that such untoward incident would not happen in future and wildlife could be protected," the bench said.
