Definitely most HS don't have full traffic in most sections Tirupati SVKDT doesn't have good load in SC TPTY and my point stands valid SL is needed for pilgrimage centers rather then flexi fare train and that no train available in that route. Pilgrims mostly travel with families and all classes of people. Durg Nizamumudin is good train with morning arrival which is the requirement and again morning dep back is not that preferred and demand will be more for evening dep anytime after 1600. NED amtitsar HS I don't think full AC needed a SF with more number of 3AC would be better. One more in central line is Indore Puri which doesn't have direct connection until now with SL given a HS. Regarding slot travellers right from VSKP VjA NGP want morning arrival but not evening arrival at Delhi where they are ni path constraints there is...
more... no point in running a SF train leaving BPL at 1400 and reaching 1200night your representatives should press for one more SF between BPL nlds may be upto Chandigarh overnight and separate train from NGP. Godwana which is introduced to NGP is extended to BSP Raigarh and now SBP. I don't if they extend further to Orissa or Andhra from fancy political representations. Already Hirakud is running should have used that slot to run 4 days between SBP and HNZM. Even Hirakud extension to VSKP is not needed instead they should have separated neelachal/ SF and given biweekly to Vskp to cater to ganges belt and also serve link to Delhi for North Andhra and southern Orissa.
