A modified automatic-door non-AC local train has arrived for safety trials on the Mumbai suburban network. The arrival follows a deadly accident on 9 June 2025 between Diva and Mumbra where five commuters died and nine others fell from a moving train.

After the accident, Railway Minister Ashwini Vaishnaw announced plans for non-AC local trains with automatic doors, with an initial target of running them by 2026; with the year nearing its end, the project is still at the trial stage. The 12-coach rake will be tested on different sections of the suburban network, and based on the trial reports it will be submitted for a fitness certificate before being cleared for passenger services.

The train features Louvre panels and roof-mounted ventilators that allow ventilation with doors closed, and vestibule connections between coaches to help distribute crowding. The Bombay High Court had previously suggested introducing closed-door trains in railway accident cases.
