Originally, the station's location was located at
Bangkok Noi railway station. It opened in 1903 as a terminus for all
Southern Line services. The station marked the 0 km point for the Southern Line. During
World War II it was bombed by the Allies as it served as a Japanese logistical centre. After the war, the station was rebuilt and was named
Thon Buri, opening in 1950. Over the years, Thon Buri Station's role as a major terminal declined as most train services moved to terminate at
Bangkok railway station, leaving only ordinary and commuter trains to end here. In 1999,
Chuan Leekpai started a project to renovate the Thon Buri Station area, a temporary class 4 railway station was constructed at the present-day location, about 800 metres from the original location. This station was to be called
Bangkok Noi Station. The original Thon Buri Station still opened for ticketing, but passengers boarded at the temporary station. However, this arrangement was later discontinued.. During
Thaksin Shinawatra's government, trains continued services to the original Thon Buri Station. Then the land around the original Thon Buri railway station was granted to the
Faculty of Medicine Siriraj Hospital. As a result, on 4 October 2003, services to the original Thon Buri Station stopped completely. The station building was given to
Mahidol University, and all services were changed to terminate at Bangkok Noi Station. On 1 January 2004, Bangkok Noi railway station was renamed
Thon Buri, and the station's class 4 status was upgraded to class 1. As of 2015, the original Thon Buri railway station building houses the
Siriraj Phimukhsthan Museum. The former temporary station is now the station in use. Despite fewer trains on the Southern Line terminating here compared to Bangkok, all distances along the Southern Line still refer to this station as kilometre 0. == See also ==
