Major accident averted after faulty signal brings trains too close on same track
A major train accident was narrowly avoided in Chennai after a motorman spotted two trains on the same track due to a signaling malfunction. This incident follows a series of recent safety lapses, prompting concerns from railway staff associations regarding system reliability.
Why it matters
Recurring signaling failures in public transport infrastructure pose severe risks to passenger safety and highlight critical maintenance and oversight issues.
A major accident was averted in Southern Railway’s Chennai Division after an alert motorman applied the brakes on spotting two trains already stationed ahead on the same track.
The serious safety lapse occurred in the Ambattur–Avadi section on March 5, 2026. A multi-departmental inquiry has been ordered into the incident, official sources told The Hindu on Friday.
According to the sources, an Electric Multiple Unit (EMU) suburban train approaching Automatic Signal S192 received a ‘Double Yellow’ aspect, authorising it to proceed with caution. As the train advanced, the motorman noticed two trains standing on the same line within visible distance. Realising the potential danger, he immediately brought the train to a halt just short of the signal, averting what could have been a serious accident.
