Rail transport in Bangkok

There are multiple planned high-speed rail lines in Thailand. The Bangkok–Nong Khai high-speed railway and Don Mueang–Suvarnabhumi–U-Tapao high-speed railway are under construction as of 2023. The Krung Thep Aphiwat Central Terminal will act as a future hub for all high-speed services.

BTS Skytrain

The Skytrain consists of three lines, totalling 70.05 kilometers (43.53 mi): Sukhumvit Line running southwards from Khu Khot Station along Phahon Yothin Road and then eastwards along Sukhumvit Road to Kheha Station in Samut Prakan. The Silom Line runs eastwards from National Stadium Station in Pathum Wan District, then southwest along Ratchadamri, Si Lom, Narathiwat Ratchanakharin and Sathon Roads, crossing the Chao Phraya passing Wong Wian Yai Station in Khlong San towards Bang Wa Station in Phasi Charoen District. Both lines are elevated, and interchange at Siam Station in Pathum Wan. And Gold Line (Bangkok) which run along Charoen Nakhon in Khlong San from Krung Thon Buri Station that interchange with Silom Line to Khlong San Station at the end.

MRT Purple Line

The MRT system opened in July 2004, and currently consists of three lines, the Blue Line (partially underground heavy rail), Purple Line (above-ground medium capacity rail) and Yellow Line (monorail). The Blue Line runs for 37.1 kilometres (23.1 mi) from Tao Poon Station in a southward arc through the east along Ratchadaphisek Road, via Hua Lamphong, where it connects to the central railway station, to Lak Song. It has 38 stations, and connects to the BTS system at BTS stations Mo Chit, Asok, Sala Daeng and Bang Wa. The Blue Line was extended to form a circle in 2020. The Purple Line opened in 2016.

Although initial passenger numbers were low and their service area remains limited to the inner city, these systems have become indispensable to many commuters. The BTS reported an average of 392,167 daily trips in 2010, while the MRT had 178,334 passenger trips per day. However, relatively high fare prices have kept these systems inaccessible to a portion of the population.

The Airport Rail Link, opened in August 2010 after many delays, connects the city centre to Suvarnabhumi Airport in Samut Prakan Province to the east. It is operated by the SRT, and offers services between the airport and Makkasan where it connects with Phetchaburi Station of the MRT. It terminates at Phaya Thai Station, where it connects to the BTS. Its eight stations span a distance of 29 kilometres (18 mi).

The Red Line Mass Transit System Project is a commuter rail system serving the Bangkok Metropolitan Region. Construction began in January 2009 and free public trial operation began on 2 August 2021, with full commercial service beginning on November 29, 2021 when Bang Sue Grand Station opened. It consists of two lines, the Dark Red Line and Light Red Line.

The entire Mass Rapid Transit Master Plan in Bangkok Metropolitan Region consists of eight main lines and four feeder lines totalling 508 kilometres (316 mi) to be completed by 2029.

New lines under construction are the Orange Line and two monorail lines - the Pink Line and the Yellow Line - which both commenced construction in 2017, as well as an extension to the Purple Line and extensions to the Airport Rail Link.
