Darshan bro, just FYI, I know u know this fact, but just letting u know.... Vande Bharat Express (as of now) should cover 2 trips in a day... urs is a good one with 7h20mins travel and avg speed of 81km/hr... but to my understanding Vande Bharat Express will be successful if it has these factors:-

1. Timings flexible to the passengers
2....
more...

Tier-1/Tier-2 cities which ur's is there.. so no problem.. but in general...
3. Have a good avg speed of atleast 80+ km/hr..
4. Trains r promising and try not to affect the other trains going in the same direction... best example MAS MYS VB and Shatabdi with just 10mins difference from departing at Chennai but having difference of I think 30mins or more at Mysuru Jn.

Regarding the 4th point, it's ideal to have the train which is opposite to the Shatabdi (if any) in order to avoid clashes (that depends on the zone)

So coming back to ur train, which is a good one, as the other RFan which I tagged, said, for IT sector, may or may not have that boost (not that sure cause I can see MAS MYS VB having good boost for Bengaluru) but for tourist factor, yes it's possible depending on the zone in which VB is running....

U would have seen the new upcoming VB from Howrah to New Jalpaiguri Jn launching from 30 Dec... that's quite sad to see the avg speed only 71km/hr... I personally feel that the concept of VB is missing... had it been some other connection like urs, having 80+ then that would be a successful one....

VB, having the max speed of 180km/hr but as of current times, can go max of 130-160km/hr depending on the zones, and now the upcoming VB having only 71km/hr avg speed.. don't know if that would be hit or miss.... but taking the tourist factor, maybe it could be a hit.....

I know long post....😄😄 but just thought of sharing my point of view.....
