This train stops at numerous stations so the IR catering staff belonging to station kitchens may enter into your train at stoppages like Asansol, Madhupur, Jha Jha, Patna Jn, Mughalsarai, Varanasi, Lucknow, Bareilly, Moradabad, Saharanpur, Ambala Cantt, Ludhiana and Jalandhar City. You should also carry your own home cooked food along with snacks items like biscuits, namkeen mixture, chips, etc. as a back up. Sorry for the late reply since I log in on weekends. Happy Journey :)
