IRCTC's eCatering service is accessible through its website and mobile application. Passengers can simply enter their PNR (Passenger Name Record) number or train details to browse a curated list of partner restaurants and food providers available at their upcoming train stops.

Once the passengers have chosen their preferred meal options, they can place their orders and make secure online payments. The orders are then relayed to the respective restaurants, which prepare the meals fresh and deliver them to the specified train stations at the scheduled arrival time of the train.
