Indian Prime Minister Manmohan Singh has expressed his condolences to the families of the victims of the train disaster.

The cause of the accident is still under investigation. Witnesses said when the train was running at full speed, there were sparks on the tracks.

In June last year, over 200 people were killed when a passenger train was hit by a cargo train in the eastern state of West Bengal.

India has one of the largest but old railway networks in the world.
