MFP deserves another dedicated train to Delhi instead of Saharsa or Darbhanga. You're from Samastipur, right ? So you must be knowing about the huge chunk of population living in Muzaffarpur. MFP is the largest city of North Bihar, yet it has only two dedicated trains to Delhi (GR still being weekly). While Jaynagar and Saharsa, being much smaller and lesser developed than MFP, have 4 dedicated trains to Delhi. Is it fair at all ?
To be honest, Dhanbad and Muzaffarpur are the most neglected stations in ECR, and most of the people will agree with this statement.
