First ACOI Shankargarh was electrified fastly so that coal loaded goods trains coming from Jharkhand side not need loco change at ACOI from eloco to diesel just for 40-45 kms upto Shankargarh for Shankargarh new Thermal Power Plant.
Thereafter the Allahabad unit of CORE, whose responsibility was only upto Manikpur in the ACOI - Itarsi full section electrification, completed its responsibility by extending the complete electrification upto Manikpur (from Shankargarh).
Also, as no train still runs by eloco from Mkp to Nyn, may this be the reason for leaving 2 km section from...
more... Lkjn- Nyn for electrification even after poles placement.
This is a one or two days job which may be done when JBP - MKP electrification will complete.
