If you are thinking to travel from this train to Jaipur from Varanasi,warn you that this one might make your journey seems never ending,follows lengthiest route and 7 hours late approx.
A good idea is you catch 11108 or 12559 from Varanasi or Manduadih,deboard at Allahabad Jn and catch 12403 Allahabad Jaipur SF Express.
This is a very good idea as it will save your precious 5 hours and is really fast.
