BHUBANSWAR, India — A signal repair error led to the three-train collision that killed 288 people in June, according to a Reuters report.

The news report cites a report from investigators for the Commission of Railway Safety that says workers trying to address problems at a nearby grade crossing did not have a circuit diagram, leading to faulty wiring. That caused a malfunction in the automated signaling system that sent the Cormandel Express passenger train, traveling at 80 mph, into a stationary train of iron ore. Some cars of the Cormandel Express then hit another train, the Yesvantpur-Howrah Superfast Express, leading to fatalities on both trains [see “Signal error blamed for fatal collision in India,” Trains News Wire, June 4, 2023].

More than 1,000 people were injured in the June 2 collision. The report says there were multiple lapses in Indian Railways’ signal and telecom departments and that standard operating procedures were not followed during the repairs.

  1. Very sad 🙁 I hope this leads to positive change in maintenance work and the overall safety culture of the national railway.
