The Elevated Train in Commemoration of HM the King's 6th Cycle Birthday Second line (Silom) or Silom Line is a route of the BTS Skytrain in Bangkok, Thailand. It runs eastward from the National Stadium Station in Pathum Wan District over Rama I Road and interchanges with the Sukhumvit Line at Siam BTS Station, then turns southward, following Ratchadamri, Si Lom, Narathiwat Ratchanakharin and Sathon Roads to Taksin Bridge where it crosses the Chao Phraya River and terminates at Bang Wa Station in Phasi Charoen District. The line is represented on the official BTS map in dark green.

Originally consisting of seven stations from National Stadium (W1) to Saphan Taksin (S6) when the BTS first opened 5 December 1999. A planned station at S4 was not built but is now planned for 2017 construction and opening in 2018.

A 2.2 km extension across the river to Wongwian Yai (S8) opened 15 May 2009 after many years of delay. Originally, this extension was due to open in 2007.

A further 5.3 km, 4 station extension from Wongwian Yai (S8) to Bang Wa (S12) in Phasi Charoen District was delayed for many months by the Bangkok floods of late 2011.

The first station of extension, Pho Nimit (S9) opened on 12 January 2013. The second station of the extension, Talat Phlu (S10) opened on 14 February 2013. The extension was initially operated by a separate 6 car shuttle service due to the absence of a turnout between Wongwian Yai (S8) and Talat Phlu (S10).

The remaining two stations Wutthakat (S11) and Bang Wa (S12) were opened on 5 December 2013.
