On 29 October 2023, two passenger trains collided in southern India's Vizianagaram district in Andhra Pradesh state killing at least 14 people and leaving about 60 others injured.

[3] On 29 October 2023, around 7:00 pm (13:30 UTC), the collision occurred on the Howrah–Chennai main line[4] after Visakhapatnam-Palasa Express service train stopped due to a break in an overhead cable when it was hit by an oncoming passenger train travelling from Visakhapatnam in Andhra Pradesh, to Rayagada in Odisha, derailing its three carriages, in the Vizianagaram district of Andhra Pradesh, India.

[10] According to Biswajit Sahu, Chief Public Relations Officer of East Coast Railway, a "human error" caused by "overshooting of signal" by the second train led to the collision.

[1] A preliminary probe by Indian Railways into the incident determined that the Rayagada passenger train passed two defective auto signals violating norms and held its driver and the assistant driver responsible for the collision.
