An AC SF from North Bihar to NDLS is the need of hour. This train will serve the purpose.
Also this'll be the first train to NDLS from SMI.(As Licchavi goes to ANVT and take a lot of time and late as well)
I am using the empty slot of BGP/JYG Garib Rath from DNR to SBB. And using the arrival time of Mahamana at NDLS. So no worry of congestion.

more... It'll also help the passengers from Nepal also.
