1. The train is neither going to be extended nor required owing to the decent occupancy it receives throughout the year. In fact it's currently one of the highest occupied train of JBP division. During recent times when trains like SEB is getting cancelled it was running with 23 - 24 coaches. Such is the occupancy. So chances of extension is nil, it will not be approved.
2 Regarding speedup, yes I do agree with u completely. Now in this process if it gets an early morning...
more... departure from JBP ( around 6 am) then that will be benefecial as INDB / BPL people can reach JBP by Narmada / Overnight exp & board this train.
3 For SGRL - BPL connectivity , there was already a sf train which is now stopped. Hope Railway will start these trains soon & if required they can increase the frequency of HWH BPL exp & other weekly trains.
