The Rameswaram (Boat Mail) Express, previously known as Boat Mail or Indo-Ceylon Express, is an express train that connects Rameswaram with the state capital Chennai via Devakottai. During 1900's it was a combined train and steamer ferry service between India and Ceylon (now Sri Lanka). Connecting Chennai and Colombo, the system initially utilised a rail-to-sea operation, but changed to a rail-to-sea-to-rail operation. Passengers could buy a single ticket for the journey. Now at present, it runs from Chennai Egmore to Rameswaram via Villuppuram, Kumbakonam, Trichy, Pudukkottai, Karaikkudi, Devakottai, Manamadurai, Paramakkudi, Ramanathapuram, Mandapam and Pamban.
