theses 3 Tejas already announced sir
and the reason for flop shatabdi is that there is kalka shatabdi which mostly fills from CDG and the CDG shatabdi timings are odd
and also CDG people more believes on NH-1
which is faster-better and awesome route via PNP
families...
more... preferred more Road than Railways
BTW now a days CDG shatabdi getting better response on some days its get jam pack mostly on weekend
tomorrow AVAILABLE-0296 in CC and GNWL9/WL4 in EC
so good response and i agree with u that tejas is not intro to CDG its better they intro for JAT or ASR via CDG
and currently railway is making NDLS-UMB stretch 160 mps the study is going on route
and UMB-CDG 130 mps study is going on
