  The Marine Liner (マリンライナー, Marin Rainā) is a rapid train service in Japan operated by West Japan Railway Company (JR West) and Shikoku Railway Company (JR Shikoku) since April 1988. The Marine Liner links Okayama, the capital city of Okayama Prefecture and a major station on the Sanyō Shinkansen, with Takamatsu, the capital city of Kagawa Prefecture on the island of Shikoku, via the Great Seto Bridge. Operating at a top speed of 130 km/h (81 mph), the journey takes approximately 52–63 minutes.
  
  ## Overview
  
  Since 1 October 2003, the Marine Liner has been operated by JR West 223-5000 series EMU trainsets. The first car on most Takamatsu-bound trains is a JR Shikoku 5000 series bi-level cab car with reserved seating. Previously, 213 series EMUs were used.
  
  From Okayama to Takamatsu, all Marine Liner trains stop at Chayamachi, Kojima and Sakaide. Most trains also stop at either Senoo or Hayashima, or both. Some early morning and late evening trains make additional stops at intermittent stations on the Seto-Ohashi and Yosan lines.
  
  As it is classified as a "Rapid" (快速, kaisoku) service, only a standard fare is charged for using the Marine Liner. It currently takes about one hour to cover the entire journey. A passenger may upgrade to reserved seating, in both standard seats or Green Car seats for an additional fee.
  
  A crew change for the train driver and conductor occurs at Kojima, the boundary station between the two operating railways.
