I guess regularising this is the only option available as the frequency of TVC Rajdhani might not be increased further since Goa Rajdhani has now started running for the remaining two days.
Though slots for 2 days via konkan railways ia still available, not sure whether TVC Rajdhani will be given the frequency increase. Instead railways might look for an alternative route to serve passengers from other stations :PGT, CBE, BZA sector
