YUP....the train definitely needs speed between certain sections.Once NJP-NCB section is fully doubled that will automatically happen and the time will reduce to 2 hrs from 3.5hrs.Also more runs will help the run between RNY and HMY be speeded up.Station from NHLN to RPAN should all have suitable timings so that people from Arunachal,North bank Assam and Tezpur can avail the facility.
