There is no doubt that Bangalore requires a faster dedicated train to Mumbai. In the recent past had also heard that MP from Mysuru was demanding extension of Udayan to Mysuru ...not sure what is the status on that. I am sure there will be lots of people in Bangalore who will object to that. Kurla Bngalore was extended to CBE earlier. Dont have much idea about Chalukya exp whether it used to terminate at YPR or not.
