The Valigonda rail crash occurred on 29 October 2005 between the Valigonda and Ramannapet stations, about 80 kilometres (50 mi) from Hyderabad in the Indian state of Andhra Pradesh (now located in Telangana). A flash flood swept away a small rail bridge, and a train travelling on it derailed at the broken section of the line, killing at least 116 people and injuring many others. Many people were suspected of being washed away in flooded waters. Initially sources had reported that about 150 persons could have been killed during the incident.

Accident details

Seven bogies along with the engine of Secunderabad bound Delta Fast Passenger derailed due to flash floods washing away a portion of the tracks. The accident occurred early in the morning of 29 October 2005. It was suspected that a huge irrigation tank situated upstream from the rail lines ruptured, sending thousands of gallons of water down the channel, destroying the railway bridge.

Personnel from Indian Army and Indian Navy divers were deployed for rescue services.

The area had been lashed by monsoon rains for several weeks before the accident, which had waterlogged fields and over-filled the irrigation tank, which had ruptured due to unknown factors exacerbated by the heavy rainfall. The flooding had also destroyed several roads, hampering efforts to get emergency personnel to the scene quickly. India's Junior Transport Minister commented that "little could have been done to avoid the accident".
