Chennai: A human error may have have led to the collision between Chennai Beach-Vellore local and Arakkonam-Katpadi passenger train on Tuesday night near Chennai in which 10 people were killed and 72 injured.
Preliminary reports have indicated the driver may have ignored signals and speed restrictions.
"The train was going in front when another one came and hit it from the rear," said Sunder, a passenger.
"The train was split in two and it lost control. I got injured," said Murugan, another passenger.
Rescue teams worked through the night despite bad weather, even as hospital staff worked desperately to save the patients.
"Railways did a great job, doctors did a great job. Can't thank them enough," said Rail Minister Dinesh Trivedi.
On the possible cause of accident, Trivedi said, "Coach operator should've stopped at the signal, from the data we have it seems he increased speed. I met him in Chennai, he is out of danger."
Tests have already revealed that that engine driver was neither drunk nor fatigued. But with a final report awaited, it is far from clear if human error is to be attributed to the accident that tore through the calm of the night and changed several lives forever.
