The Suvarnabhumi Airport Rail Link (Thai: รถไฟฟ้าเชื่อมท่าอากาศยานสุวรรณภูมิ, แอร์พอร์ตลิงก์ Airport Link) or SARL, is a rapid transit line in Bangkok, Thailand. The line provides as an airport rail link from Suvarnabhumi Airport, via Makkasan city air terminal, 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). Opened on August 23, 2010^[1], the 28.6-km route is the fourth rapid transit line in Bangkok, after 2 BTS and 1 MRT line. 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

The key airport link contract was signed in January 2005, and construction began in July 2005.^[2] The line is built by a consortium of B Grimm, STECON and Siemens, and is owned and operated by State Railway of Thailand (SRT). The estimated cost of the project is 25.9 billion baht.^[3]

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. Some BERTS pillars stood in the way of the new system, and after extensive debate on their suitability for reuse and demands for compensation from Hopewell, SRT decided to demolish the pillars and build new ones.^[4]

While originally scheduled to be completed by 2006, the Hopewell debacle, an extended bidding process and a series of legal challenges from property owners who had encroached on SRT's land, have 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 and full commercial service launched on 23 August 2010.

Extension continuing along the SRT Red Lines (former BERTS) alignment from Phaya Thai to Bang Sue is also planned^[5]. The line may be extended to Don Mueang (site of Don Mueang International Airport) depending on Don Muaeng Airport's usage policy. 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

The ARL operates daily from 6:00 a.m. to 12 midnight, and both the City Line and Express Line trains depart every 15 minutes. 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 or 150 Baht was introduced for the City Line and Express Line service, respectively.

Since 4 January 2011, baggage check-in service is offered to 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.

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.^[6] A promotional fare of 90/150 for a single/return trip (within 14 days) on the Express Line was also introduced.^[6]

Specifications

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 and Commuter trips 27 minutes^[3].

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 will be 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.^[7]

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.^[2]

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.
