Structure of Routes and Stations
     
  Routes  
  The BTS SkyTrain system operates in 2 lines with a total of 34 stations.  
 
The Sukhumvit Line
begins at Bearing Station and ends at Mo Chit Station, starting from Sukhumvit 85 traveling via Sukhumvit Road to Ploenchit Road, Rama I Road, Phyathai Road, Victory Monument, Paholyothin Road, Sanam Pao, Saphan Khwai and Chatuchak Park. This line is approximately 22.25 kilometers long and offers 22 service stations, including one interchange station (Siam).

The Silom Line
begins at Bang Wa Station and ends at National Stadium Station. The line starts from Ratchaphruek at the intersection with Phetchakasem Road, then passes along Ratchaphruek Road to the intersection with Wutthakat Road. The line then passes the Ratchada-Talat Phlu intersection to Tak Sin intersection, and then crosses the Chao Phraya River via Saphan Taksin to Sathorn Road. Curving left above Chong Nonsi, the line proceeds along Silom Road, passing Lumpini Park and on to Rajdamri Road. The line then curves left onto Rama I Road and interchanges with the Sukhumvit Line at Siam, before terminating at National Stadium Station. The Silom line is approximately 14.2 kilometers and serves 13 stations, including one interchange station (Siam).


The stations and track are built on a 9 meter wide viaduct, 12 meters above the road median. The structure comprises segmented concrete casts and was assembled span-by-span using dry joint and external post-tensioning within the gap of each segment. This method requires minimal construction time, ideal for the congested traffic environment of the downtown core. The viaduct support structure is made of cast concrete, 2 meters wide and 30 35 meters in length. For the Silom Line extension from Tak Sin Bridge to Bang Wa ( Ratchaphruek-Phetchakasem), the cast-insitu method is also used.
