'We received water supply for 20 minutes Wednesday morning, two days after taps dried in the area following burst of an underground water pipeline due to the mishap,' said Sangita Singh, a housewife in Zamrudpur.

The All India Institute of Medical Sciences (AIIMS) said four of the 15 workers who were injured Sunday -- when a concrete viaduct on which the rails will be laid collapsed, bringing down tonnes of steel and concrete on scores of unsuspecting workers -- were still in hospital.

The second accident occurred during the clearing operations Monday, when three cranes toppled over, injuring six more workers.
