What you save 40 Kms. See Boat mail, meenakshi, Mahal express running in useless 64 Kms long route via Thanjavur. Why these ppl should travel in such a long route? Divert them via chord line.it is taking 2 extra hours for them to go to Chennai.or why not diverting Tambaram Tirunelvaleli antyodaya to chord line? It is extremely slow and taking four extra hours? When you can't tolerate 40 Kms long route,why these people should tolerate. Let them go via chord line.
