Networks
BTS Skytrain
The Skytrain consists of three lines, totalling 70.05 kilometers (43.53 mi). The Sukhumvit Line runs 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. The Gold Line runs along Charoen Nakhon Road in Khlong San from Krung Thon Buri Station, which interchanges with the Silom Line, to Khlong San Station.
MRT (Metro)
The MRT (Metropolitan Rapid Transit) system opened in July 2004, and currently consists of four lines, the Blue Line (partially underground heavy rail), Purple Line (above-ground medium capacity rail) and Yellow Line and Pink 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, 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 Pink and Yellow monorail lines opened in 2023.
Airport Rail Link
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).
SRT and commuter rail
The SRT Red Lines, which opened in 2021 along with the Bang Sue Grand Station, serve the Bangkok Metropolitan Region. It consists of two lines, the Dark Red Line and Light Red Line.
