It cant be managed, as AWB/MAO JS manages with 3 Rake to cover maintenance slack!! If it was possible, then AWB & MAO JS would have been running with dedicated Rake & no need of RSA would have arrived!! The main reason of this Shatabdi running till Karmali not MAO is to manage Maintenance TAT @ CSTM!!
Further, JS capacity dont improve as the coaches gonna will remain earmarked as Shatabdi with different fare structure!! It dont will help 2S Passengers!!
With different run, the one who dont get CC in JS,...
more... can easily shift into Shatabdi!!
Further, both hav some different stoppage scenario along with quite distance through GAP time frame!!
