SRT Dark Red Line
The SRT Dark Red Line (also referred to as Thani Ratthaya Line (Thai: รถไฟชานเมือง สายธานีรัถยา)), is part of the SRT Red Line suburban railway system to serve the greater Bangkok Metropolitan Region running for 26 km (16 mi) between Krung Thep Aphiwat Central Terminal and Rangsit.
In mid-November 2020, the Minister of Transport announced that free trial operations would operate from March 2021 with full-service operations expected from November 2021. In late February 2021, the SRT confirmed that free trial operations will commence on 26 March 2021 with full commercial operations starting on 28 July 2021. However, in July 2021 the SRT again postponed the free trial operations until 2 August 2021.
The line finally opened for trial operations on 2 August 2021. Full commercial services began on 29 November 2021.
A much delayed 8.84 km (5.49 mi) extension of the line from Rangsit to Thammasat University was due to be tendered in June 2022. However, this was later delayed to December 2022 and then until February 2023. With the 14 May 2023 national elections and the ongoing delays in the formation of a new government, it is unlikely that the tenders will be issued until late 2023. In late June, a MOT source expressed that the extension is likely be taken to Cabinet for approval in October 2023 and if approved, a tender could be issued in the first quarter of 2024.
The SRT Dark Red Line starts at the new Krung Thep Aphiwat Central Terminal heading north for 26 km (16.16 mi) via Don Mueang and terminates at Rangsit in Pathum Thani Province. The line will then be extended 8.84 km (5.49 mi) north from Rangsit to the Thammasat University Rangsit campus.
From Krung Thep Aphiwat Central Terminal the line will be extended 11 km (6.84 mi) south via Phaya Thai to Hua Lamphong station. The final section of the line will run southeast from Hua Lamphong via Wongwian Yai for 39 km (24.23 mi) to Maha Chai in Samut Sakhon Province along the current Maha Chai railway alignment.
When fully completed, the line will run on a north–south axis through Bangkok, from Thammasat University's Rangsit campus in Pathum Thani Province to Maha Chai in Samut Sakhon Province for a full length of nearly 87 km (54.06 mi).
In 2004, in conjunction with OTP, the SRT began formulating plans for a new, modern suburban network in Bangkok along existing SRT alignments to replace the existing, limited services. On 7 November 2006, the Thai Cabinet passed a resolution to approve the framework of the new network with the SRT Light Red line being DMU operations while the SRT Dark Red Light would be EMU. At the time, it was expected that the full line could be completed within 15–20 years. In February 2009, the Thai government secured a 24 billion baht (US$685 million) loan from the Japanese Government for the initial segment of the 87 km (54 mi) line. The first Phase from Bang Sue to Rangsit was approved in 2010 but delayed due to a complicated 2.5 year contractual dispute.
