Delhi International Airport Limited (DIAL) has issued the tender to build an air train or automated people mover (APM) that will have four stops — T2/3, T1, Aerocity and cargo city. The GMR-backed DIAL has given the alignment for this 7.7-km route. Transiting between Delhi Airport’s Terminal 3 and T2 on one side and T1 on the other will finally be a breeze before the end of calendar year 2027. The airport operator is likely to get bids for what will be India’s first air train at an airport, in Oct. and Nov. The winning bidder will be decided based on the cost quoted by different parties and whether they offer a revenue share model or seek viability gap funding for the project, as per a report.
