Tha Maeklong Railway is a result from merging of two railway lines. In 1901, Tachin Railway Ltd. is founded and received a permission from the monarch to build a railway line from Bangkok to Samut Sakhon called Mahachai Line. This line started operating in 1904. A year later, Maeklong Railway company also open a new railway line called Ban Laem Line. These two line merged together in 1907 and has become the Maeklong Railway Ltd. Original objective of this railway is to transport goods from the fishing port in Samut Sakhon and Samut Songkram to the Bangkok markets.
During the World War II in 1942, the railway fell under the Thai military authority and was nationalized by Thai Government in 1946. The State Railway of Thailand (SRT) has run this railway line since 1952 and completely took over into SRT in 1955. Due to the discontinuation of the terminus at Khlong San, Wongwian Yai has become the new terminal station instead.
The railway has become famous for the Maeklong Railway Market that situated along the sides of the railway. Maeklong Railway Market also has its nickname called Talat Rom Hup in Thai (Umbrella pulldown market). It is one of the largest fresh seafood markets in Thailand.
