Parashuram and Ernad: Both connect TN and KA. Both run between NCJ to MAQ.
Another set of trains: MAQ CBE Passenger express and another SF.
What is the use for TN and KA by such trains?
I will accept them as useful if MAQ CBE goes upto Salem/ Thanjavur/ Mayiladuthurai. Or NCJ MAQ goes upto Karwar/ Kundapura/ Udupi.
