Ideally MAS should have stopping in Gummidipoondi, Tiruvallur, Avadi, Tambaram, Chengalpattu, Perambur, Thiruvotriyur for at least select long distance trains if not all. Even last year passengers from Tiruvallur demanded stop for coimbatore bound trains. Railways know the issue well but refuse doing this why because for them MAS is not a priority their priority lies elsewhere ! It would be no exaggeration If I say MAS is treated like GT express !!
