Little bit Speeding up is possible for this train but 1 hr full speed is not possible.
And If the departure from HWH is made late, then it will arrive CSTM by 10 pm which will be bit late.
And also Proper LHB standard PM will not be possible at CSTM as yard will get only one night i.e 8 hrs for it. if it would have been day time arrivals in CR like Jnaneswari or Azad hind , then PM is easier. But late night arrival and quickly early morning departure...
more... will not help the maintenance of train. Instead let the PM be with SER i.e after LHB introduction, let this ICF rake be dedicated to Shri jagannath completely and Gitanjali be given LHB. And the Departure timing at HWH be made bit early like 11 am or 12.30 pm so that it arives CSTM bit early evening. And similarly departure from Mumbai be made bit late (6am is too early) like 7 am or 8 am similar to Pushpak express.
