Yes economic way if we think then SR and SCR E locos are enough but poll they asked which will be first E Loco shed in karnataka so the guess is KJM and also in future if all together south rail lines get electrified their might be deficient of ELOCO so that time their will he opportunity for SWR to introduce self E loco shed with less investment and that will be KJM. Even after 5 years when UBL get Electrified lines via GTL BAY GDG then political game can change KJM to UBL shed to become ELOCO as its Head quarters of SWR and will have soft edge over KJM Politically and officially.
