The goods train derailed in the morning and the work to clear it has been going on at a war footing, a spokesman of the Konkan Railway Corporation Limited said.
Four bogies have derailed and it may take more than 10 hours to restore the traffic on this route, he said.
The restoration work has become difficult as the goods train derailed in the tunnel between Sangameshwar and Nivsar, he said.
Ukashi, situated 19 kms away from Ratnagiri, is the only railway station in India to have part of its platform in the tunnel.
