Now the weekend train for Ayodhya starys from Patliputra station to setve larger crowd from Bihar ant the rake has been replaced with modern LHB COACHES. click here
I know better than you I am from Banaras only but this thing is also same applied to that route also I had seen many trains gets delayed heavily on that route.And recently akaltakht was delayed by two + hours at DDU but it makeup near sultanpur so everytime trains don't gets looped on ddu-bsb it depends on controlling by NR.
My view is on short route less time travel so that pax don't feel uncomfortable in journey. There is other route also through ballia that will also be less distance than this.
If all train goes thru short route than many areas won't get connectivity of trains.
A new train through this route should start from MFP Overnight regular train.And From Patna use this PPTA-CDG rake to Ayodhya through BSB/Ballia.
Current route is also good.
This is overnight so, no issue.
However from AYC Side TT is slow.
In UP TT is somehow good but may gets delayed before Muzaffarpur as trains gets delayed here.In down TT is so much pathetic not to be called as good overnight from Ayodhya side.Well this train will have maximum pax from motihari sides.
