Need to extend this train upto Jogbani(JBN) Because there are only one train(tri-weekly) from Jogbani to Kolkata(via- KIR, MLDT, NFK, RPH, BHP, BWN, NH) It will be very helpful for the people of Jogbani, Forbesganj, Purnea and BAK loop line(JRLE, AZ, KWAE, NDAE, BDC) to reach Howrah at morning.
This train, 15711 currently running as a weekly train, if it extended upto Jogbani then it's frequency also need to increase(tri-weekly at least).
