India's first driverless air train will be built at Delhi Airport

• Delhi International Airport Limited is developing an Automated People Mover system—also referred to as the 'Air Train'—for the Indira Gandhi International Airport in Delhi.

• This proposed system marks India's first driverless airport air train and is designed to provide connectivity between the various terminals along a 7.7-kilometer route.

• An Automated People Mover is a driverless, rail-based transportation system used to transport passengers over short distances within airports, metro hubs, and large campuses.

• The Delhi Airport project has been planned as a hybrid system comprising both elevated and surface-level sections, with 5.7 kilometers of the route running on an elevated structure and 2 kilometers at surface level.

• This Air Train is designed to interconnect Terminals 1, 2, and 3, as well as Aerocity and Cargo City, within the Indira Gandhi International Airport complex. The objective of this system is to enhance convenience for transit passengers and airport users throughout the entire airport complex.

• The estimated cost for this project is projected to range between approximately ₹2,000 crore and ₹4,000 crore.

• The project is expected to become operational by late 2027 or in 2028, although some estimates suggest that its completion could take until 2029.
