Sir , for your kind info Rewari -Jakhal (via ROK) is 210 km which is (RE-ROK=81km + ROK-JHL=129km = 210KM ) and RE-HSR-JHL (224KM) which has only 14 km difference.
2nd passenger are much more via RE-HSR compared to ROK-RE
3rd ROK-JHL already have almost 7 trains in which 4 or 5 trains are for SVDK and RE-HSR only have 1 train for SVDK / JAT
And...
more... ur point for reversal of loco , i think it benefitize railway as small check up or cleaning of train or materials for pentry car .
