Delhi Airport to have air trains

Delhi’s Indira Gandhi International Airport will soon be at par with New York's JFK, London Heathrow, Hong Kong and Zurich airports as per as Air Train is concerned. This is a dedicated metro corridor that helps people to commute from one terminal to other. Now passengers coming from T3 to T1 or vice versa need to take AC buses available for terminal transfers, which take 30 minutes for each trip. However after the air train is built, the transfer wouldn’t take more than 12 minutes.

From 2020, T2, which is the old international airport would be a brand new terminal T 4 and would share the load of traffic. This initiative of air train was supposed to be started in 2020 along with the new terminal. However with the volume of traffic at Delhi airport increasing every quarter the authority plans to begin the work at the earliest. Delhi International Airport Pvt Ltd (DIAL) would start expanding T1 and laying the fourth runway from July this year.

"By our estimates, the line should be 5.5-km-long with 3km underground section and 2.5km on ground. The average costing of each kilometre of under and on ground Metro line is up to Rs 500 crore and Rs 200 crore. It should cost Rs 1,500-2,000 crore. All this will be known for sure once DMRC gives its report to DIAL,” a source told the Economic Times.
