The SRT Light Red Line is part of the SRT Red Lines suburban railway system serving the Bangkok Metropolitan Region, open for free trial service between Bang Sue and Taling Chan since 2 August 2021. The completed line will run east–west from Sala Ya in Phutthamonthon District of Nakhon Pathom Province to Hua Mak Railway Station in Bangkok.

The segment from Taling Chan to Bang Son (15 km) opened for limited, free trial service between December 5, 2012 and 13 January 2014 with a limited 12 services a day operated on the line until all services were fully suspended on due to a lack of rolling stock. After completion of electrification work and the construction of Bang Sue station, the line reopened for trial operation in 2021.

Route Alignment[]

The first 15 km section runs from Bang Sue Intercity Terminal in Chatuchak District to Bang Son where it interchanges with the MRT Purple Line. It then continues west and crosses the Chao Phraya River to the Thonburi side of Bangkok before continuing farther west to Taling Chan where it terminates. Bang Sue Intercity Terminal provides interchange with the SRT Dark Red Line and MRT Blue Line. The line will be extended 12 km west to Sala Ya in Phutthamonthon District of Nakhon Pathom Province. Finally, the line will be extended south from Bang Sue via Phaya Thai and then east to Hua Mak Railway Station in the east of Bangkok where it will interchange with the MRT Yellow Line.

History[]

Start of construction[]

Bang Son Commuter station on SRT Light Red Line

The contract for the initial stages from Taling Chan to Bang Sue was signed on 15 December 2008, with the contract awarded to the Unique-Chun Wo consortium.[3] Construction started in early 2010 but was delayed for a few months due to the late 2011 floods in Bangkok which inundated the route. Construction was completed by the 3rd quarter of 2012. Testing began in September 2012 for a 3-month period.[4]

2012-4 trial operation and suspension[]

The line opened for free limited trial service on 5 December 2012 between Taling Chan Station and Bang Son Station. The line was operated with 2 refurbished DMUs running a very limited service. There were only 6 services each way a day every 60 minutes from 6am to 8am and from 4pm to 7pm. As such, only a few hundred passengers a day rode the service.[5] On 14 September 2013, weekend services were cancelled.[6] Effective as of 13 January 2014, all services were suspended until further notice.

Electrification and 2021 reopening[]

The reopening of the SRT Light Red line was contingent upon the completion of the new Bang Sue Intercity Terminal, delivery of rolling stock and installation of the overhead catenary electrical system between Bang Sue–Taling Chan which was funded as part of the SRT Dark Red Line contract 3. Electrification was to be completed by 2020. By the end of September 2019, Electrical and Signalling installation was at 45.60%.[7]

As of June 2020, installation of the catenary system was at 76.82%.[8] The line was expected to reopen in January 2021[9] after test runs began in late October 2020.[10] In mid November 2020, the Minister of Transport announced that free trial operations would operate from March to May 2021 with full service operations expected in November 2021.[11] In late February 2021, the SRT confirmed that free trial operations would commence on 26 March 2021 with full commercial operations starting on 28 July 2021.[12] In July, the SRT postponed the service and the free trial operations commenced on 2 August 2021 with full commercial operations due to start on 1 November 2021.[13][2]

Rolling stock[]

The 3rd contract for the Dark Red Line is for electrical and systems (E&S) and procuring EMU rolling stock for both the SRT Light Red and SRT Dark Red lines. An overhead catenary electrical system will be installed. As of April 2014, only 2 bidders remained but one of the bidding consortiums was disqualified on due to the fact that one of the consortium members (Maru Beni Corp) had convictions for bribery in an Indonesian bidding process.[14]

This left MHSC Consortium (Mitsubishi and Hitachi and Sumitomo) as the sole bidder qualified for the contract. However, their bid of 28,899 billions Baht was above the SRT median price of 26 billions baht which was set in 2010. The MHSC Consortium argued that their bid reflects 2013 prices after the minimum wage increase of January 2012. Finally, after a 2-year delay in the bidding process, in July 2014 JICA approved the loan for Contract 3.[15] However, the coup of May 2014 delayed finalization leading to further review and negotiations. By mid 2016, negotiations had concluded and Hitachi promised that all rolling stock for the Dark Red line would be delivered by 2020.[16] The contract specifies 25 EMUs consisting of ten 4 car sets and fifteen 6 car sets for 130 cars in total.

In late September 2019, the first 2 sets of rolling stock were shipped from Japan[17] and both arrived in Thailand at Laem Chabang port on 12 October 2019 for shipment to Bangkok.[18] By March 2020, 5 sets had been delivered.[19]

As of July 2020, 13 sets - 7 of the 6 car sets and 6 of the 4 car sets - of the ordered 25 sets of rolling stock had been delivered with a further 2 sets due to be delivered by August 2020.[20] By the end of September 2020, 21 sets had been delivered - 13 of the 6 car sets and 8 of the 4 car sets - with the final 4 sets to be delivered in October.[21]

Future extensions[]

In July 2016, the cabinet approved the construction of the Bang Sue–Phaya Thai–Makkasan–Hua Mak segment.[22] However, the 12 km, 4 station western extension Taling Chan to Salaya was due to be tendered first by September 2018[23] and then slated for the 2nd half of 2019.[24] However, the tender has further been delayed until 2021 as the Transport Minister has requested the new Department of Railways to investigate conducting PPP tenders for this extension.[25] On 10 February 2021, the Department of Railways announced that in April 2021 the SRT would issue the tenders for the west extensions to Salaya and from Taling Chan to Siriraj.[26][27]

Construction segments based on M-Map:[28]

Phase Segment Length Progress
I Bang Sue-Taling Chan 15 km (9.32 mi) Free trial service from 2 August 2021
II Taling Chan-Salaya 12 km (7.46 mi) Tender April 2021
III Taling Chan-Siraj 6.5 km (4.04 mi) Tender April 2021
IV Bang Sue-Hua Mak 25 km (15.53 mi) Planned
V Salaya-Nakhon Pathom 30 km (18.64 mi) Suggested long term

Phase II Taling Chan-Salaya Extension[]

The SRT Light Red Line is planned to be extended by 12 km west to Salaya.[29] 4 stations are planned be built along the existing SRT corridor;[30] 1) Ban Chimplee station, 2) Kanchanaphisek (Phutthamonthon Sai 2), 3) Sala Thammasob, 4) Salaya.

The western extension from Taling Chan to Salaya was originally planned to be tendered by September 2018 after receiving Thai Cabinet approval in July 2016.[31] This was then delayed to the 2nd half of 2019.[32] However, the tender has further been delayed until 2021 as the Transport Minister has requested the new Department of Railways to investigate conducting PPP tenders for this extension.[33]

Phase III Taling Chan-Siriraj spur line[]

The SRT operates existing intercity services from Thonburi station to Kanchananburi. This line is planned to be converted to a spur line of the existing Light Red line, from Taling Chan to Thonburi/ Siriraj. In August 2012, the SRT proposed that 3 stations be built for this 6.5 km route:[34] 1) Talingchan Floating Market station at Bang Ramad, 2) Charansanitwongse station (interchange with the MRT Blue Line) 3) Thonburi/Siraraj station (interchange with the MRT Orange Line). Originally the MRT Orange Line was planned to be built along this alignment to Taling Chan. This spur line will be constructed once the extension to Salaya has started construction.

Phase IV Bang Sue–Hua Mak[]

There will be stations at Ratchawithi, Phaya Thai, Makkasan and Hua Mak.

This section can only be progressed once Bang Sue Central Station is completed and will have a narrow right of way given the current ARL viaduct and ARL stations.[35]

Infill stations[]

Two additional infill stations on either side of the Chao Praya river have been approved to be built, at Rama 6 bridge and Bang Kruay (EGAT).[36] However, as of July 2020 no contracts have been tendered to build these two stations given the delays with the Salaya section tender.
