Some opposition was there for doubling works in that 17kms section at Cansaulim area I think same people are opposing electrification works. Otherwise SWRs pace of electrification is good. In few months MAO QLM and Tinaighat CLR CRS will take place also i noticed few electric poles put up in CLR QLM Ghat section too in a youtube video.
Very soon trains like Amaravati and JSME VSG will run with elocos upto Castle Rock.
