LHB with 130 MPS isn't gonna be of any help to the Proposed Dhanbad Train, see the condition of Sampoorna Kranti Express, Purushottam Express or Jasidih Super Duper Special.
Jharkhand Swarna Jayanti Express is not that Punctual ki Allahabad would give any priority to any other train running on that slot.
The only remedy is change of route either through Jhansi- Banda- Manikpur-Chheoki-Mughalsarai Route or through Farrukhabad- Kanpur- Unnao- Unchahar- Phaphamau- Janghai- Varanasi Route
