15909/15910 Avadh Assam Express Should be extended up to Dibrugarh Railway Station coz its the only daily train towards Avadh Section.Its really become difficult for Dibrugarh people to convey from New Tinsukia Railway Station.They have to spend Rs.1000.00 or more to reach Dibrugarh by Cab.Since Dibrugarh is the Last Station in this Section.So,it must be extended upto Dibrugarh.
