once upon a time TBM skipped by most trains. north chennai doesnt have halts because of congestion, now quadrapling happening so for benefit of chennai south coastal andhra i added those stops. i skipped PSA CHE TDD too. if i add some in orissa these will also need to be added then i need to add TBM MPA SRGM LLI too. on the whole it makes it normal express.
