In my opinion 12393 and many other SF/EXP from DDU to Delhi side should be diverted via Gyanpur route or Poorva route.Congustion between DDU-Cheoki is too much by freights, Passenger trains from CNB and ET etc sides.It will help to ease the traffic since trains usually struck in these sections.And already to create space for other zone trains many bsb origin train terminal changed to bsbs.
