I think once Daund E loco shed is complete.They may plan to allot E link between DD - LTT.The problem right now is Availability of E Link's are very less and in Mumbai division CR they don't have links like P4 and P7,even KYN which earlier had P7 had been transferred to AJNI.So All we can do is wait For CR's upcoming e loco shed to be complete which is in progress.Similarly Wadi and SBC don't have proper facilities For LSA to run E loco on that route.
