Tanintharyi Line is a gauge railway line in Myanmar's southernmost region, Tanintharyi Region, operated by Myanma Railways. The line runs from Mawlamyine Railway Station (Moulmein) to the Dawei area, with connections to Yangon Central Railway Station, it is under construction extending towards Myeik from the current terminus of Thayetchaung Station, which lies just after Dawei Station. Current section in operation includes the part from Mawlamyaing Station to Thayetchaung. It is expected to become a part of a pan-Asian railway network, allowing spur connections specifically to Thailand. A spur connection (95 km as the crow flies) between the SRT rail head at Nam Tok railway station in Kanchanaburi Province to Dawei Station through mountains is planned by Thai interests backed by Japanese funding, though other rail connections are certainly possible.
1994 saw the start of construction of the initially isolated 1600NaN0 Ye-Dawei (Tavoy) railway, completed March 1998. This was later joined to the route north at Ye by the new 250m (820feet) road/rail bridge across the Ye River, opened November 2003.In April 2008, the tracks were extended across the 2.4km (01.5miles) Thanlwin Bridge, a road/rail bridge located in Moulmein, provision having been made in its design when it was opened a few years earlier. This allowed the long isolated section south to Ye and later Dawei (Tavoy) to receive trains from the north of the country. A 20-mile extension to Thayetchaung Station was opened to traffic in June 2011.[1]
