It wil get eloco from vskp very soon. Actually some trials and tests are going on in that route thats why many high priority trains on that route are yet to get an eloco link including, ratna superfast, dhn-allp exp, hte-ypr, hte-bnc, tata-ypr. Though excluding the fact that ratna superfast is getting eloco from rourkela which is fair enough but the loco change from visakhapatnam will be updated very soon ! Dont worry, all the technological upgrades take time ЁЯШК
