why not swr can run a duranto express between sbc to aii
But that will be not humsafar, humsafar concept was not as 3E..
I guess that they have named fully 3E trains as gati shakti
SWR is generally just a M/E zone. You'll find some or the other M/Es connecting every part of the zone. The rare SF trains are essentially like premium trains only, since premium trains barely traverse through the zone.
Now, asking for an actual premium train to Mumbai/Gujarat and beyond definitely doesn't seem possible, even though it is entirely feasible. Just because of how things work with SWR.
In fact, Bengaluru division (the smallest division of SWR) solely maintains all three premium trains (Raj+Shatabdi+Duronto) of SWR. That's wild.
SWR could have started VSG NZM Rajdhani instead of NR starting the one from MAO but they only care about freight revenue and also they simply cant or don't want to run trains from VSG via KRCL. They simply don't want to explore the tourism potential of Goa.
I used to think the same about Jan Shatabdi Exp until they introduced BSBS-PNBE Janshatabdi and many more.. so may be abhi new Duronto introduce nahin ho rahi hai baad me kar bhi sakte hain.
Duronto is a good concept in my opinion..
Rajdhani jaisi facilities aur priority two major Cities ke bich.. i agree Duronto ka concept ruin jarur hua hai.
