CHENNAI, APRIL 18TH
The metro rail department has cancelled all direct train services between Koyambedu and Chennai Airport through Alandur. It was in November 2016 that the service kick-started in trial basis, catering to popular demand.
A notice at the Koyambedu metro station reads about cancellation of services between Koyambedu and airport since 15th April, the reason being maintenance work. There is no clue about restoration of service.
