The Bangkok Mass Transit System, commonly known as the BTS Skytrain (Thai: รถไฟฟ้าบีทีเอส RTGS: rot fai fa [BTS]), is an elevated rapid transit system in Bangkok, Thailand. It is operated by Bangkok Mass Transit System PCL (BTSC), a subsidiary of BTS Group Holdings, under a concession granted by the Bangkok Metropolitan Administration (BMA) which owns the lines. The system consists of 62 stations along three lines with a combined route length of 70.05 kilometers (43.53 mi). The BTS Sukhumvit Line runs northwards and south-eastwards, terminating at Khu Khot and Kheha respectively. The BTS Silom Line which serves Silom and Sathon Roads, the central business district of Bangkok, terminates at National Stadium and Bang Wa. The Gold Line people mover runs from Krung Thon Buri to Klong San and serves Iconsiam. The lines interchange at Siam station and Krung Thon Buri. The system is formally known as "The Elevated Train in Commemoration of HM the King's 6th Cycle Birthday" (รถไฟฟ้าเฉลิมพระเกียรติ 6 รอบ พระชนมพรรษา).
Besides the three BTS lines, Bangkok's rapid transit system includes the underground and elevated Mass Rapid Transit (MRT) lines, the Bus Rapid Transit System (BRT), and the elevated Airport Rail Link (ARL), serving several stations before reaching Suvarnabhumi Airport, and the SRT Red Lines of the State Railway of Thailand.
