Bangkok is the location of [[Krung Thep Aphiwat Central Terminal]], the new main terminus of the national rail network operated by the [[State Railway of Thailand]] (SRT). The older terminus, [[Bangkok (Hua Lamphong) railway station]], which was the main station for Bangkok for over a century, remains in use. The SRT operates long-distance intercity services from Krung Thep Aphiwat, while commuter trains running to and from the outskirts of the city during the rush hour continue to operate at Bangkok (Hua Lamphong).

Bangkok is served by four rapid transit systems: the [[BTS Skytrain]], the [[MRT (Bangkok)|MRT]], the [[SRT Red Lines]], and the elevated [[Airport Rail Link (Bangkok)|Airport Rail Link]]. Although proposals for the development of rapid transit in Bangkok had been made since 1975,<ref>{{cite journal|title=Bangkok transport system development: what went wrong?|first=Wiroj|last=Rujopakarn|journal=Journal of the Eastern Asia Society for Transportation Studies|volume=5|date=October 2003|pages=3302–15}}</ref> it was only in 1999 that the BTS finally began operation.

The BTS consists of two lines, [[Sukhumvit Line|Sukhumvit]] and [[Silom Line|Silom]], with 59 stations along {{convert|68.25|km}}.<ref>{{cite web |title=Company's Profile |url=https://www.bts.co.th/eng/info/info-history.html |website=Bangkok Mass Transit System PCL Ltd. |access-date=30 July 2019 |archive-date=20 September 2022 |archive-url=https://web.archive.org/web/20220920215549/https://www.bts.co.th/eng/info/info-history.html |url-status=live }}</ref> The MRT opened for use in July 2004, and currently consists of two metro lines, the [[MRT Blue Line|Blue Line]] and [[MRT Purple Line|Purple Line]] with 53 stations along {{convert|70.6|km}}, and two [[monorail]] lines: the [[Yellow Line (Bangkok)|Yellow Line]] which opened in July 2023, and the [[Pink Line (Bangkok)|Pink Line]] that opened in January 2024. The Airport Rail Link, opened in August 2010, connects the city centre to Suvarnabhumi Airport to the east. Its eight stations span a distance of {{convert|28.6|km}}. The [[SRT Red Lines]] commuter rail lines opened in 2021, and consist of two lines, the [[SRT Dark Red Line]] and [[SRT Light Red Line]] with currently 14 stations along {{convert|41|km}}.

Although initial passenger numbers were low and their service area was limited to the inner city until the 2016 opening of the [[MRT Purple Line|Purple Line]], which serves the [[Nonthaburi]] area, these systems have become indispensable to many commuters. The BTS reported an average of 600,000 daily trips in 2012,<ref>{{cite web|url=http://www.nationmultimedia.com/business/BTS-Group-Holding-Plc-30176106.html|title=BTS Group Holdings – The Nation|access-date=24 September 2024|archive-date=3 March 2016|archive-url=https://web.archive.org/web/20160303231831/http://www.nationmultimedia.com/business/BTS-Group-Holding-Plc-30176106.html|url-status=dead}}</ref> while the MRT had 240,000 passenger trips per day.<ref>{{cite web|url=http://www.nationmultimedia.com/business/New-BMCL-boss-eyes-boosting-commercial-revenue-30172472.html|title=New BMCL boss eyes boosting commercial revenue – The Nation|access-date=24 September 2024|archive-date=18 November 2018|archive-url=https://web.archive.org/web/20181118164201/http://www.nationmultimedia.com/business/New-BMCL-boss-eyes-boosting-commercial-revenue-30172472.html|url-status=dead}}</ref>

{{As of|2024}}, construction work is ongoing to extend the city-wide transit system's reach according to the [[Mass Rapid Transit Master Plan in Bangkok Metropolitan Region]], which consists of eight main lines and four feeder lines totaling {{convert|508|km}} to be completed by 2029.
