I'm not demanding I'm just telling u the meaning of revolution
Take eg. of same train(sampoorna kranti)
It has no commercial stop between NDLS to PNBE but now CNB And MGS are commercial stop in place of technical stop..it called change. Yrr
And about extension to DBG is only that NDLS to HWA have lots of train but in case of NDLS to DBG...
more... thERE Is only countable train ..
By running an extra train it would couse traffic and economic tension on railway
Did u under stand sir
