District Magistrate N S Nigam and hospital sources have put the death toll at 148.
All trains plying on the Sardiha and Khemasuli route in Jhargram will now have a speed limit of 15 km per hour at night, Handa said.
Around 145 passengers were being treated in various hospitals in Midnapore, Kharagpur and Kolkata, he said.
The train services on the Kharagpur-Tatanagar section of the South Eastern Railway (SER) resumed on Sunday morning after restoration of both up and down tracks which had remained obstructed after the tragedy.
The accident occurred on Friday after 13 coaches of the Kurla-bound express went off the tracks and five of them were crushed by a goods train coming from the opposite direction.
