Angry relatives staged a protest Saturday on the tracks where a speeding train ploughed into crowds watching fireworks, killing about 60 people in the latest disaster to bedevil India's railway network.

The Jalandhar-Amritsar express hit scores of people who had gathered on the tracks Friday to get a view of a firework-packed effigy of the demon king Ravana for a Hindu festival.

Many of the victims were dismembered beyond recognition and police said it would take several days to complete the identification of the dead.

Some desperate parents went from hospital to hospital in the northern city of Amritsar on Saturday looking for missing children, while the first funerals of some victims were held.

Hardeep Singh, chief medical officer for Amritsar, told AFP 59 deaths had been confirmed and 90 people had been injured, with seven in critical condition.

Singh said only 25 bodies had been identified so far. Amritsar's main hospital did not have enough space in its morgue, and some corpses were laid outside.

The disaster led to new demands for safety reforms to India's accident-plagued railway system, which records thousands of deaths each year.

Punjab state governor V.P. Singh Badnore said: "Those who need to be punished will be punished and accountability will be fixed."

Scores of protesters who gathered on the railway tracks condemned the Punjab state government and demanded action against the driver who was questioned by police on Saturday. Others blocked a nearby road.

Police moved the protesters off the tracks and brought in reinforcements to control a crowd of hundreds that gathered around the scene of the disaster.

Investigators said victims did not hear the train because the drone of the locomotive was drowned out by firecrackers. Another train had narrowly missed the crowds two minutes earlier, officials said.

According to media reports, the driver told police he did not see the revellers until the last second because he had come around a bend in the dark into the firework smoke.

As the blame game spread, police said they had given permission for the display for the annual Dussehra festival fireworks but that organisers did not have approval from the city, health department and fire brigade.
