As far as my information is concerned Itarsi/WAP-4 came once with 57274 - Tirupati - Hubballi Passenger to Ballari Junction. Itarsi electric loco is the farthest electric loco with passenger train to visit Ballari Junction untill now. Jhansi electric loco is the farthest electric loco to visit Ballari Junction untill now if electric locos with freight trains are taken into consideration
