Airport Rail Link
The 30-billion baht Suvarnabhumi Airport Link was opened on 23 August 2010, after multiple delays. The Airport Rail Link (ARL) is operated by SRTET, a subsidiary company of the State Railway of Thailand. The standard gauge line is 28.6 kilometers long and is elevated for most its length, running mostly above existing regional railway lines and parallel to the No. 7 Motorway and Si Rat Expressway. There is a short at-grade/underground segment as the line approaches the passenger terminal building of Suvarnabhumi Airport. The ARL has two interchange stations, namely Phaya Thai (changing for BTS Green Line services) and Makkasan (linking Phetchaburi station of the MRT Blue Line).
Two train services are operated: the non-stop Express Line trains run between Suvarnabhumi and Makkasan (at a maximum speed of 160 km/hour); the commuter City Line trains that run between Suvarnabhumi and Phaya Thai, calling at all stations.[39] At the end of 2010, Makkasan station will also serve as the City Airport Terminal with parking and baggage check-in facilities offered to passengers using the Express Line. In the future, the ARL will complement the SRT Red Line commuter service, which comprises two meter gauge, dual-track lines.
The ARL may also be extended from Phaya Thai to Don Mueang via Bang Sue, if the old Don Mueang International Airport is reopened for civil aviation under a dual-aiport policy. The Airport Rail Link operates daily from 6 a.m. to 12 midnight. A single-trip journey costs between 15 and 45 Baht or 150 Baht on the City Line and Express Line service, respectively. Journeys on an Express Line train (non-stop to Makksan) and the City Line train (six stops to Phaya Thai) takes 15 and 27 minutes, respectively. Suvarnabhumi station is located right under the main terminal building (B1 Level, two floors below the Arrival Hall). As the connection walkway linking Makkasan and Phetchaburi MRT stations is currently under construction, passengers changing to other mass transit lines are advised to take a City Line train to Phaya Thai and change to the BTS Skytrain from there. Baggage check-in facilities for passengers travelling on flights operated by Thai Airways International and Bangkok Airways are offered at Makkasan station (the city air terminal) from 8 a.m. to 9 p.m., daily. Passengers must check in their baggage at least 3 hours prior to the flight departure, or up to 12 hours in advance, and are required to purchase an Express Line ticket to Suvarnabhumi Airport.
Regional train
Meanwhile, SRT provides a suburban commuter train service between Hua Takhe (the nearest station to Suvarnabhumi on the East line) and the northern suburban city of Rangsit via downtown Bangkok and the old Don Mueang Airport. The train also connects with BTS and MRT at Phaya Thai and Phetchaburi stations respectively. Passengers pay a flat fare of Bt30. A shuttle bus service linking the airport with Hua Takhe railway station is provided by BMTA for Bt15. The train service is currently not as popular as the bus service because it requires a shuttle bus connection. The service will be stopped when the Airport Express Link is completed.
