City Line Train

The Airport Rail Link (Thai: รถไฟฟ้าเชื่อมท่าอากาศยานสุวรรณภูมิ) is a express and commuter rail in Bangkok, Thailand. The line provides as an airport rail link from Suvarnabhumi Airport, via Makkasan, to Phaya Thai station in central Bangkok. Most of the line is on a viaduct over the main eastern railway. It is owned by State Railway of Thailand (SRT) and operated by SRT subsidiary SRT Electrified Train (SRTET). The 28.6 kilometers (17.8 mi) Airport Rail Link opened for service on August 23, 2010.[2] Services consists of two Express Lines, a 15-minute nonstop service between the Makkasan city air terminal and the airport and an 18-minute nonstop service between Phaya Thai and the airport, and the City Line, a commuter rail service with 8 stations.

History[edit]

The key airport link contract was signed in January 2005, and construction began in July 2005.[3] The line was built by a consortium of B Grimm, STECON and Siemens, is operated by the SRTET (SRT Electric Train Company) which is a 100% owned subsidiary of the State Railway of Thailand (SRT). The cost of the project was 25.9 billion baht.[4]

The line is built largely along the same alignment as the failed Bangkok Elevated Road and Train System (BERTS) project, started by Hopewell but stopped in 1997 when only 10% had been completed. Many previously constructed BERTS pillars stood in the way of the new system. After extensive debate and an engineering review on their suitability for use in the ARL project - and demands for compensation from Hopewell - the SRT eventually decided to demolish the pillars and build new ones.[5]

While originally scheduled to be completed by 2006, the Hopewell debacle, an extended bidding process and a series of legal challenges from squatters & property owners who had encroached on SRT's land, repeatedly delayed the project. Initial test runs were conducted in October 2009, with a free limited trial service open to the public running from April 2010. Full commercial services were launched on 23 August 2010.

An extension north along the SRT Red Lines (former BERTS) corridor from Phaya Thai to Don Mueang Airport via the new Bang Sue Intercity Terminal (under construction) is planned.[6] In addition, the eastern section of the SRT Light Red Line commuter rapid transit, if built, will utilize the right of way of the SRL, with interchange provided at SARL at Phayathai, Makkasan and Hua Mak station.

Passive provision is being made for an extension of the rail link to a future second terminal at Suvarnabhumi airport.[citation needed]

Operations[edit]

The SARL operates daily from 6:00 a.m. to 12 midnight, with commuter City Line (blue) trains departing every 12–15 minutes and the Express Line (Red) trains departing every 60 minutes.

City Line[edit]

The commuter/suburban City Line stops at all 8 stations. It is used by many residents and students in the eastern suburbs as well as airport staff. The Cityline has suffered from significant overcrowding since 2012. Accordingly, since 2013 extra City Line services have been introduced using one Express Line set. The City Line currently averages around 50 000 pax a day on weekdays and 30 000 a day on weekends.[7]

Express Line[edit]

On 1 June 2011, additional Express Line services became available between Phaya Thai station and the airport with a total journey time of 18 minutes.[8] This effectively means that there are two distinct Express Services: one to/from Phaya Thai with a 60 minute headway; and one to/from Makkasan Terminal also with a 60 minute headway. This is due to a design flaw in the original laying of the rail which meant that the Express line track terminates at Makkasan and does not connect with the Cityline track which run on the outer side of the Express line, to Phayathai. The SRT allocated 17m baht in Feb 2012 to rectify this problem.[9] However, as of July 2014 the two tracks had not been connected.

At the end of April 2014, the Phaya Thai Express service has been suspended for 12 months due to insufficient rolling stock being available while long term, overhaul maintenance of the Express rolling stock is undertaken. As such, the hourly Makkasan Express service is only averaging 400 pax a day.

Fares[edit]

Between 23 August 2010 and 3 January 2011, passengers were charged a promotional fare of 15 Baht or 100 Baht on the City Line and Express Line service, respectively. On 4 January 2011, a standard fare of 15 to 45 Baht for the City Line was introduced. The Express Line was priced at 150 baht but insufficient patronage lead to a promotional fare of 90/150 for a single/return trip (within 14 days) on the Express Line from 1 June 2011.[8] This promotional fare has been extended every since since and is currently extended until the end of 2014.

City Air Terminal (Makkasan Station) Check in service[edit]

Since 4 January 2011, a baggage check-in service began for passengers traveling on flights operated by Thai Airways International from 8 a.m. to 9 p.m., daily. Passengers checking in at Makkasan station (the city air terminal) are required to purchase an Express Line ticket and check in at least 3 hours prior to flight departure, or up to 12 hours in advance. Bangkok Airways discontinued baggage check-in service in this facility on 13 June 2011. However, very few passengers use the Makkasan station check in service with as few as 20 or less per day.[10] The SRTET stated that they wanted to encourage further airlines to use the City check in service in early 2014 with a target of 1000 people a day by late 2014.[11] However, in July 2014 the SRTET stated that it would most likely cease check in operations. Only 10 people were using it a day with only 200 pieces of luggage checked in each month yet the service was costly the SRTET 5.27m baht a month.[12]

Specifications[edit]

The standard gauge line is 28.6 km long and is elevated, running above the existing eastern railway, with an underground terminal at the airport. Both non-stop Suvarnabhumi Airport Express services and "stopping" Suvarnabhumi Airport City Line commuter services are operated, with Express journeys taking 15 minutes from Makkasan and 18 minutes from Phaya Thai while Commuter trips take 27 minutes.[4]

Siemens supplied nine Desiro Class 360/2 trainsets. The only significant difference from the UK units is a much larger air-conditioning pod on the roof, providing extra power to cope with the Thai climate. City services is operated by five three-car trains, and the Express services by four trainsets with a fourth car for check-in baggage. The first trains left Germany in September 2007, and testing in Bangkok began in March 2008.[13] On 15 May 2012 the Thai Cabinet approved a budget of 5.2 billion baht for the SRT to order 7 new, 4 car sets of Siemens Desiro rolling stock to be delivered by 2014.[14] However, as of June 2013 no order for new rolling stock had yet been placed. The Ministry of Transport was considering purchasing cheaper Chinese (CNR) or Spanish (CAF) rolling stock which would require changing the Siemens closed signalling system to an open system.[15]

The line is electrified at 25 kV AC. All stations were built to accommodate 10-car trains, and the express train platform of Makkasan station and all platforms at Suvarnabhumi are fitted with platform automatic screen doors. The top speed is 160 km/h, but the short distances between the stations imply that commuter services don't reach that speed.[3]

At Makkasan and Suvarnabhumi, both lines have their own tracks and platforms. At Hua Mak the express line can bypass the city line via a passing loop.

Rolling stock[edit]

The 9 sets of Siemens Desiro II trains were built in Krefeld, Germany.[16]

4 trains - 4 cars, red colour - are used for the two separate express service between Makkasan & Phayathai and Suvarnabhumi airport.[16] The other 5 trains - 3 cars, blue colour - are used for commuter Cityline service stopping at all 8 stations on the Airport line.[16]

New rolling stock to be ordered[edit]

Approval was granted by the MOT for the SRT to purchase 7 new, 4 cars sets of rolling stock in early 2012 due to overcrowding and the urgent need to provide extra rolling stock. Currently, one Express set is being used for Cityline services. During, 2013 the MOT reviewed the purchase intention to consider cheaper CNR rolling stock. In December 2013, the Thai Cabinet approved 4.9 billion baht for the 7 new sets of rolling stock.[17] As of mid 2014, a supplier has not been selected but the SRT has indicated it intention to invite bidders to tender for new rolling stock in September 2014.[18]

Future extension[edit]

Since its inception, the ARL was always proposed to be extended to the new SRT Bang Sue Terminal (under construction) and ultimately Don Mueang Airport (DMK). The 21.8 km extension - 3.5 km underground and 18.3 km elevated - would consist of 5 stations beyond the current terminus at Phaya Thai: Chitladda Palace (underground), Bang Sue Intercity Terminal (under construction), Bang Khen, Laksi and Don Mueang.

Originally, it was thought that work on the extension would not commence until after 2016. However, the Thai Cabinet designated a two-airport policy in March 2012 encouraging airlines, particularly LCCs, to move to DMK.[19] This resulted in an advance of the ARL extension timeline.[20] The SRT budgeted for the extension in its 2013 budget and the 27 billion baht extension was planned to be tendered in the later half of 2013. However, a political crisis in the last 3 months of 2013 and into 2014 delayed any further progression of the project. The military coup of May 2014 resulted in a military administration which has decided not to fund the project in 2014.

Future Rayong HSR (eastern seaboard HSR)[edit]

It should also be noted that the ARL is intended to be the backbone of the future High Speed Rail line (HSR) to Chonburi and Rayong which was scheduled to be completed by 2018. However, the military coup of May 2014 subsequently resulted in the military administrators deferring all HSR line proposals. Essentially, the Eastern HSR line will be considered by the next civilian government. Elections are scheduled for October 2015.
