Concept is good, but giving Red for four reasons:
1) Should be 'Futuristic'
2) SDAH-BPC section is in a fragile condition and can't support such a fast train. Hence please reduce some speed in entire SDAH-MLDT section.
3) Overnight SF and unreserved- surely will be flop
4)...
more... You have visioned to extend up to Gangtok, but that TT is inappropriate too. NJP to Gangtok will be a 130-140KM section and it's impossible to complete that in only 2Hrs 20Mnts.
Please rectify these sections and it will be nice.
