Such media report should be taken with a pinch of salt. I don't foresee a VB between RNC and PNBE in the near future. First things first, a VB between HWH and BSB via - Grand Chord would attract good patronage, IMO.
Regarding HWH - PNBE sector - sooner or later, a VB would definitely get introduced. Yes, the Shatabdi in this sector got downgraded into Janshatabdi but, that was in 2004-05. Now, this train runs with LHB rake. The rake length has increased from 8( shatabdi rake) to 21( present...
more... LHB rake). And, it has very good patronage.
