SWR always has been behind in providing in good intrastate services and that is the reason why most of the kannadigas get irked when the neighbors ask for train services with our cities as stations for PM best example would be mangalore, bidar or kalaburagi. I don’t have much idea about udyan n ltt-cbe because i stay in dharwad and i travel between dwr-dvg-sbc mostly. Talking abt Chalukya, yes it was extended to pdy/ten but the delay in receiving and dispatching is based on SR ability to accommodate train in their network. So the blame is not totally on SWR.
