Bangkok Mass Transit System (BTS) or Skytrain is the elevated metro system in Bangkok, Thailand, operated by Bangkok Mass Transit System Public Company Limited (BTSC) under a concession granted by the Bangkok Metropolitan Administration (BMA). With 23 stations along 2 lines, it was opened on December 5, 1999 by HRH Princess Maha Chakri Sirindhorn. The Sukhumvit line runs northwards and eastwards, terminating at Mo Chit and On Nut respectively; the Silom line plies Silom and Sathon, the Central Business District of Bangkok, terminating at the National Stadium and Saphan Taksin (Taksin Bridge). The lines interchange at Siam station and have a combined route distance of 23 km. The Skytrain is formally known as the Elevated Train in Commemoration of HM the King's 6th Cycle Birthday because it was opened to the public on HM King Bhumibol Adulyadej's 72nd birthday.

Bangkok also has an underground railway system called the MRT or unofficially the Metro.
