Discussion over , NCR has not given any trains you are happy that indicates sheer impunity to serve PRYJ only, extending 200 km till SBDR will not snatch any thing from prayagraj and SBDR is not a feasible place to do SM or PM bcoz NCR never intended to develop it . So what you said for ALJN, ETW, FZD is applicable to SBDR too and putting Chanda fort comparison with SGRL is truly absurd. Sooner or later many trains from prayagraj will be sent here don't worry about it. Also just check how many buses run from SKTN/SGRL to BSB/PRYJ/LKO will clearly tell you why it needs more train.
