i feel SR should give 1st preference to south bound overnight trains like nellai,,pearl city,anantapuri,pothigai,manglore mail,salem exp becoz in these trains most no of tamil nadu pax travels, also will be helpful fighting against bus lobby that take away many of potential pax
given that SR is in losses,these overnight trains provide huge potential of earning becoz according to railway fare slab,more distance you travel less you pay,
with above mentioned trains running with LHB with HOG will save lots of money for railway
so...
more... my 1st preference to above trains
followed by TNSK{bcoz its sampark kranti}
followed by Tamil nadu,and GT
NOTE that my above plan might take 2020,but looks most effective to me looking at passengers prospective and profits
hopefully by that time LHB with 24 coaches will also become a reality,bcoz right now running with 22 coaches are the biggest hurdle for any LHB train.
suggestions are welcome
