If i am remembering correctly a massive offlink with P7 BIA goes to Adi section with Puri Adi express and BIA is not far then 900KM from Hwh side so that HWH can be take these Locos to SER SRC shed after Conversion of SRC shed compatible to 3 phase loco Ajni is good but it have less number of P7 which all are distributed to all india, so i think BIA is in shed which is currently not in use even with Amarkantak Bia P7 just roam on home network ie DURG BSP only and one BIA p7 run with JS on RIG G section, another one is run with Raipur Korba passenger and 1 runs with BSP NGP ICE. there is still some BIA p-7 resting on ELS BIA,
