Agree. If MAQ to MAS via Karnataka is with SR, then, you can have trains via HAS, SBC to MAS. The distance is less by around 200 Kms. SR will definitely find ways to scrap this useless HMRDC agreement and run trains from Tamil Nadu to Mangaluru, Udupi, Kollur, Murudeshwar and Gokarna. SR will run trains from North Kerala to Davanagere, Hubli, Shimoga, Ballari and further even to Hyderabad. Coordination will become better.
Even SCR will get better, if they get area upto Pune (MRJ-Pune as it was earlier). SCR can have entire east coast to west coast (Goa to Vizag) in single zone control.

more... zones, more divisions, and so more problems.
