SRTET decided to suspend the Makkasan Express due to low passenger numbers and insufficient rolling stock. There have been no Express Services since this time. It will eventually be replaced with high speed train services once the Don Mueang–Suvarnabhumi–U-Tapao high-speed railway is complete. Fares Standard fare for the City Line is between 15–45 baht depending on distance. (The Express Line was priced between 90/150 baht for one way/return). City Air Terminal check-in From 4 January 2011, a baggage check-in service began for passengers traveling on flights operated by Thai Airways, 08:00–21:00. Passengers checking in at Makkasan station (the city air terminal) were required to purchase an Express Line ticket and check in at least between 3 and 12 hours in prior to flight departure. Bangkok Airways discontinued baggage check-in service in this facility on 13 June 2011. However, very few passengers—20 or fewer per day—used the Makkasan station check-in service. The SRTET stated that they wanted to encourage further airlines to use the City check in service in early 2014 with a target of 1,000 people a day by late 2014. However, in July 2014 the SRTET stated that it would most likely cease check-in operations as only 10 people were using it a day with only 200 pieces of luggage checked in each month. The service was costing SRTET 5.27m baht a month. All check-in services ceased in September 2014 when the Express service was suspended. Specifications The line is long and is elevated, running above the existing eastern railway, with an underground terminal at the airport. Commuter trips take 27 minutes from Phaya Thai to Suvarnabhumi Airport. Unlike most railways in Thailand, which use meter-gauge railways, the Airport Rail Link uses standard-gauge railways. The Airport Rail Link is electrified via overhead lines at . 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 , but the short distances between the stations do not permit commuter services to reach that speed. 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 Nine four-car and three-car Siemens Desiro EMUs based on the British Rail Class 360 are used.
