The Mass Rapid Transit Authority (MRTA) has issued a request for tender submission for the extension of Thailand’s Purple Line electric rail network, which will run between Tao Poon and Rat Burana. The process will follow International Competitive Bidding (ICB) guidelines and bid envelopes will be available for purchase until December 24, 2021.
Under the THB78 billion railway extension project, the existing Purple Line will be extended by 23 km. The extension will be completed in six phases, the first of which will see the line extended by three stations, or 4.8 km, beyond its current terminus in Tao Poon to the Thailand National Library. Three further stations will be built between the National Library of Thailand and Phan Fa in the second phase, covering a distance of 2.4 km, while three more stations will be constructed between Phan Fa and the Phra Phuttha Yodfa Bridge in the third phase.
The line will be expanded to Dao Khanong and Khru Nai in the fourth and fifth phases, respectively, while the sixth phase will focus on the development of a railway signalling system along the route.
The line will run from Nonthaburi to Samut Prakan, passing through the districts of Thon Buri and Phra Nakhon. Construction work is set to commence in 2022 with the extension scheduled to open to traffic in 2027.
