Delhi’s Indira Gandhi International Airport (IGI) is set to undergo a major infrastructure transformation with the launch of India’s first driverless air train system (Automated People Mover – APM). The project, estimated at around ₹3,000–₹4,000 crore, aims to revolutionize passenger movement inside the airport by connecting key terminals and airport zones seamlessly.
The project is being developed by Delhi International Airport Limited (DIAL) and is expected to significantly reduce travel time within the airport ecosystem.
The proposed air train will run on a 7.7-kilometre dedicated corridor, linking Terminal 1, Terminal 2, Terminal 3, Aerocity, and the cargo hub.
The system will operate as a fully automated, driverless transport network, designed to ensure faster and smoother passenger transfers. It is modeled after similar systems used in international airports such as Zurich, Seoul, and Jakarta.
DIAL has decided to fund the project internally rather than using a concessionaire model, ensuring faster execution and better control over operations.
The upcoming system includes several advanced features:
The system will also enhance environmental sustainability by reducing fuel-based vehicle movement within airport premises.
Delhi Airport is one of the busiest airports in the world, handling millions of passengers annually. The air train will significantly improve inter-terminal connectivity, especially for transit passengers.
Currently, passengers rely on shuttle buses or walking, which can be time-consuming during peak hours. The new system will drastically reduce transfer time, making IGI Airport more efficient and globally competitive.
The Delhi Airport air train project represents a major step in modernizing India’s aviation infrastructure. As air travel demand continues to grow rapidly, airports are under pressure to improve passenger handling capacity and reduce congestion.
This project introduces advanced driverless transport technology in India’s airport ecosystem for the first time. It aligns with the global trend of smart mobility systems that prioritize speed, automation, and sustainability.
By reducing reliance on shuttle buses and fuel-based vehicles, the air train will help cut carbon emissions inside airport premises, supporting India’s green transport goals.
For millions of passengers using IGI Airport, especially transit flyers, the system will drastically reduce waiting time and improve travel comfort. Faster transfers will also enhance Delhi Airport’s global ranking.
As India’s busiest airport, IGI plays a crucial role in international connectivity. This project strengthens India’s position as a growing global aviation hub, aligning with long-term infrastructure development goals.
Indira Gandhi International Airport has evolved into one of the busiest airports in the world, handling record passenger traffic in recent years. Over time, the airport has expanded with multiple terminals, including Terminal 3, one of the largest in the world.
To manage rising passenger demand, several upgrades have been introduced, including metro connectivity through the Airport Express Line and terminal expansion projects.
Despite these developments, inter-terminal connectivity has remained a challenge due to the large airport area. The idea of an Automated People Mover has been under discussion for years but was delayed due to funding and planning challenges.
The current ₹4,000 crore air train project marks the first concrete step toward solving this long-standing connectivity issue and aligning the airport with global aviation standards.
The Delhi IGI Airport Air Train Project is a proposed driverless Automated People Mover (APM) system designed to improve connectivity between terminals and major airport zones.
The project is estimated to cost around ₹3,000 to ₹4,000 crore, making it one of the largest airport mobility upgrades in India.
It will connect Terminal 1, Terminal 2, Terminal 3, Aerocity, and the cargo area through a dedicated corridor.
The project is being developed by Delhi International Airport Limited (DIAL).
The main benefit is faster, seamless, and automated passenger movement between terminals, reducing dependency on shuttle buses and improving travel efficiency.
Transit passengers are expected to travel free of cost, though final fare policy may be confirmed later by authorities.
Yes, this will be India’s first driverless airport-based Automated People Mover system.
