India Unveils First Non-AC Local Train with Automatic Doors, Marking a Major Safety Leap for Mumbai’s Suburban Network

In a transformative step toward improving commuter safety, Indian Railways has introduced the country’s first non-air-conditioned (non-AC) suburban train equipped with automatic doors—a long-awaited reform aimed at addressing the persistent dangers of overcrowding in Mumbai’s vast rail network.

The 12-coach Electric Multiple Unit (EMU), recently rolled out at the Kurla Carshed in Mumbai, is currently in its prototype stage and will undergo mandatory certification trials by the Research Designs and Standards Organisation (RDSO). Officials indicate that the evaluation process could take approximately three months before the train is approved for passenger service.

A Safety Reform Driven by Tragedy

The initiative follows the tragic Mumbra incident of June 2025, where five commuters lost their lives after falling from overcrowded trains. In response, the Railway Board mandated the installation of automatic door systems in all new non-AC suburban rakes.

Data underscores the urgency of this reform. Between January 2014 and May 2025, as many as 6,760 passengers died and 14,257 were injured in fall-related incidents—overwhelmingly linked to open-door non-AC coaches. In contrast, air-conditioned local trains, which already feature automatic doors, have reported zero such fatalities.

Balancing Safety with Affordability

Despite the proven safety of AC trains, affordability remains a critical concern. A standard non-AC ticket from Churchgate to Virar costs approximately ₹20, compared to ₹115 for an AC journey. This price disparity ensures that non-AC trains remain the primary mode of transport for Mumbai’s estimated 6.6 million daily commuters.

The newly introduced rake, manufactured by the Integral Coach Factory (ICF), seeks to bridge this gap by combining enhanced safety features with cost-effective travel.

Key Specifications

• Total Coaches: 12
• Passenger Capacity: 5,698
• Seating Capacity: 1,003
• Compartments: 19 (including luggage sections)
• Coach Composition: 8 second-class and 4 first-class coaches
• Reserved Sections: Dedicated spaces for women and Divyang (differently-abled) passengers

Advanced Automatic Door System

At the core of the upgrade is a fully automated door mechanism designed to eliminate unsafe practices such as footboard travel:

• Doors open within 3 seconds and close in 4 seconds
• A 30-second dwell time aligns with station halts
• Obstruction detection prevents accidental closures
• Interlocking ensures trains cannot move unless doors are fully shut
• Anti-drag systems safeguard passengers from being pulled along moving trains

According to officials, the system is expected to significantly reduce accidents while promoting disciplined boarding and alighting.

Addressing the Ventilation Challenge

A major engineering challenge in closed-door non-AC trains has been ensuring adequate ventilation. Previous trials recorded carbon dioxide levels rising up to 2.5 times inside sealed coaches. To mitigate this, the new design incorporates:

• Louvred doors to facilitate continuous airflow
• Larger windows, nearly double the size of older coaches
• Roof-mounted ventilation units with enhanced capacity (10,000 cubic metres/hour)
• Multiple window configurations for improved air circulation
• Up to two-thirds openable window space

These features aim to maintain passenger comfort, even during peak-hour congestion.

Additional Passenger-Centric Enhancements

The rake also introduces several modern safety and comfort features:

• Fire detection systems
• Improved alarm mechanisms to reduce misuse
• Passenger information display systems
• Emergency talk-back units near doors
• Sealed gangways for inter-coach movement
• Internal sliding doors for emergency exits
• Redesigned seating with improved legroom

A Step Toward a Larger Transformation

Mumbai’s suburban railway network—one of the busiest in the world—spans 376 route kilometres and operates over 3,200 services daily across Central and Western Railways. Despite this extensive capacity, overcrowding continues to pose serious risks.

While the current train remains a prototype pending rigorous testing, it represents a critical interim solution. Simultaneously, Indian Railways is advancing long-term plans under the Mumbai Urban Transport Project (MUTP)-III and IIIA, which envisage the introduction of 238 fully air-conditioned rakes at an estimated cost of ₹19,293 crore, with rollout expected from 2028 onward.

Until then, the introduction of closed-door non-AC trains signals a pragmatic and much-needed evolution—merging safety, accessibility, and affordability for millions of daily commuters.
