The connectivity has improved a lot. Now connected with Darbhanga by road via Bahera, SPJ connectivity by road is old story but still train for Delhi and Guwahati are minimum. Even the DBG-NJP Express is not taking this route.
Neglect of this route is very old tradition.
Still railway plays trains on old Div pattern: SPJ-SHC Passenger where KGG is not under SPJ so big organizational fragmentation too causes operational problems. Still no Passenger train to KIR via ROA.
