No need to offend bro ЁЯШВ
Sorry for confusion, I didn't meant that Navyug express should run from Bengaluru.
What I meant is Bengaluru deserves a NEW train to SVDK more than...
more... Mangaluru (preferably via Hassan, Ballary like you have mentioned). Since Bengaluru is a much bigger city than Mangaluru still lacks connectivity to northern cities beyond Chandigarh.
Remember Goa also lacks proper connectivity to SVDK and Mumbai has only Swaraj express which is not even daily so even if they are going to reintroduce SVDK to TEN via konkan is best option.
