Hello SWR, why always special trains from sbc,mys,ubl.Why you dont look in these route i.e gdg-hpt-bay to run long distance trains like trains to patna/mfp/ghy/sdah/indb/ndls from hubli/vasco.
I think only #18047/8 vsg-hwh exp can not serve the peoples of kbl,hpt,tngl,bay, as there are many peoples who are working in bellary district, but no proper train connectivity .
Suggestion from me run special train to pnbe/mfp/ghy via ubl-bay-gtl-kcg-ngp, surely these will hit train and you make it permanent if hit these train in these route.
