Phra Phutthachai Line: shortcut linking Eastern Line and the Northeastern Line (Thailand), there are only freight trains on this line, and there is one tunnel, Phra Phutthachai Tunnel.
In 1941, SRT built a 17-kilometer railway line into Cambodia, but five years later, that line was removed because of World War II ending.[1] In 1953, the SRT rebuilt the 6-kilometer rail line into Cambodia upon Cambodia's request and opened it on 22 April 1955, though it was closed again in 1961 due to strained Cambodia-Thailand relations.[1] The cross-border link between Aranyaprathet briefly Poipet briefly opened in April 2019,[4] but closed again in April 2020 due to the COVID-19 pandemic.[5] In 2023, the border was reopened for freight transport.[6]
Chuk Samet Main Line
In July 1989, the Eastern LineChachoengsao Junction–Sattahip Commercial Port section opened. Freight trains continued to end of the line to Sattahip Commercial Port (Chuk Samet) until the early 2000s when the port's commercial role decreased. This resulted in passenger services terminating at Ban Phlu Ta Luang railway station and freight trains stopped operating on the line entirely. In 2002–2003, some services continued down the line to Jamboree Station, built specially for the 20th World Scout Jamboree held in Sattahip. In the 2010s, Samae San railway halt was constructed with some weekend tourist rail services terminating here, but this was short-lived.
On 10 November 2023, the line between Ban Phlu Ta Luang and Chuk Samet reopened, in the hopes of boosting tourism by providing closer access to U-Tapao International Airport, as well as direct rail access to HTMS Chakri Naruebet located at Sattahip Naval Base.[3][7]
