Simply jsme k naam pe VB via mainline chalana ka koi sense nhi h
Granted that the biggest player in the region, patna us route pe aayega but even then it serves no real purpose, as pnbe has all sorts of trains to both bsb and hwh, including VBs
Running it via jsme gaya also makes no sense, as they are most likely to skip the entire KG section, so kisi chhote station k bhala hone ka bhi koi scene nhi h
Unless...
more... of course the whole scheme is designed as a giant middle finger to dhanbad
please wait...Translate to EnglishDude, running VB via mainline just doesn't make any damn sense. Sure, Patna might benefit from it being the big shot around here, but ain't no point to it when PNBE already has trains to BSB and HWH, with VBs included. And sending it via JSME Gaya ain't any better, 'cause they'd probably just skip the whole KG area, so there ain't no benefit for any small station either. Unless, of course, it's all just a big eff you to Dhanbad.
