GTL shed is mainly to cater to SCR region and once WADI line becomes electrified fully. SWR needs its own shed to cater to trains in MYS-SBC-YPR-DMM sector. Once SBC-MYS is electrified fully, you need a minimum of 5 to 10 e-locos to cater to SBC-MYS trains itself leave alone the rest. and then come the long distance trains from SBC/MYS/YPR going towards WADI/GNT/BZA via DMM and also SBC-BWT sector. SR will soon run out of locos to lend to SWR as some of the SR lines are also being electrified at a fast pace.
