Offtopic, but I think SWR should launch one SBC - MAS MEMU in this timetable. Would be interesting.
Old RFs probably remember the 55/56 Bengaluru - Chennai Passenger.
Which then became the Bengaluru - Arakkonam Passenger.
And...
more... then became Jolarpettai - Arakkonam Passenger.
And now runs as Jolarpettai - Arakkonam MEMU Express.
