Not needed at all. It used to run between FBD-DLI several years back, then extended till BWN and when Mr Jaiswal beacme minister, he got it extended till CNB. Train runs as local express train between CNB-FBD. 90% seats are reserved from FGR/FBD/MNQ only and few of them from KNJ/GSJ.
Only connectivity between FBD-DLI so plz spare it. Any extension will make it delayed.
