Shanmugaiah and Kurunthamma, an elderly couple from Tenkasi in Tamil Nadu, displayed remarkable courage and presence of mind when they noticed a truck had fallen on a railway track near their house. They ran in the dark, carrying a torchlight, and managed to alert the locopilot of an approaching train by waving the light frantically. The train stopped just in time, avoiding a major accident that could have claimed many lives. The couple was praised by the railway authorities and the public for their heroic act.
