The Delhi airport is likely to get an ''air train'' by 2022 for seamless movement of passengers between terminals, a source privy to the development said.
"By the time the current phase of expansion is over by 2022, Delhi airport will become quite big with annual passenger handling capacity reaching 10 crore. Therefore, an air train is being considered right now to be built by 2022," said a source privy to the development.
Currently, passengers at Delhi airport move from one terminal to another using shuttle bus service.
