For several survivors of the Odisha train accident who arrived in Tamil Nadu on Sunday in a special train, the trauma they endured is unlikely to dissipate soon and it was more than shock and disbelief for them.

A woman, who is a native of Kerala said she had only seen accidents on televisions and when she experienced it herself, she was terrified. "The bed sheets given to passengers were used to carry the injured and it turned red with blood; a dreadful scene," she told reporters here.
