The route covers major Uttar Pradesh and North Bihar stations
The reported stops include Ghaziabad, Kanpur, Aishbagh, Gonda, Gorakhpur, Bagaha, Narkatiaganj, Bettiah, Motihari, Muzaffarpur and Samastipur. Passengers should confirm the boarding stop printed on their ticket.

Train 04098 is scheduled daily from October 10 to November 25
The announced New Delhi–Darbhanga festival special will run as train 04098 every day during this period. The service is intended to add capacity before Diwali and Chhath, when confirmed berths on regular Bihar-bound trains become difficult to find.

Samastipur gets a scheduled 30-minute halt
The published timetable places train 04098 at Samastipur from 10:05 am to 10:35 am on the second day, before its noon arrival at Darbhanga. That stop makes the special useful beyond Darbhanga, including for connecting journeys in North Bihar.

Train 04097 is scheduled back from October 11 to November 26
The return service from Darbhanga to New Delhi will operate as train 04097, beginning one day after the outbound service. The published schedule provides 47 trips in each direction, making this a daily seasonal train rather than a weekly special.

The Delhi-to-Darbhanga journey is scheduled for about 26½ hours
Train 04098 is reported to depart New Delhi at 9:30 am and reach Darbhanga at noon the next day. That produces a scheduled journey of 26 hours and 30 minutes, excluding any delay on the day of travel.

The return departure is 3 pm, but passengers must recheck before booking
Train 04097 is reported to leave Darbhanga at 3 pm, and the special is reported to have 24 coaches. Because festival-train timings, composition and operating days can be revised, passengers should verify 04097 or 04098 in NTES and IRCTC for their exact date.
