Kovai Extension will be a big challenge. SR might not think about it.
But SR can think of extending one train. If not extending, atleast a new train in this route. It will be big benifit.
Like, if we consider SALEM, after SBC ICE, next train is 12695 in night. SR can run the new ICE after SBC ICE, Starting MAS around 9AM. reaching ERS around 9PM or 8PM. Return can start around 6 from ERS
