Thailandhas entered the 21st century with several modern, electric rail systems that are helping ease traffic congestion and make travel around the city more comfortable and convenient.
Thailandhas two primary metropolitan rail lines, the BTS skytrain, consisting of two Green Lines (Sukhumvit and Silom) and the first of several planned MRT underground lines, the Blue Line.
The BTS skytrain runs the length ofSukhumvit Road, a major thoroughfare where numerous hotels, shops, and restaurants are located, and travels north to Mo Chit, where there is an interchange between the BTS skytrain and the MRT subway near the northern bus terminal and the JJ Weekend Market. The other BTS/MRT interchange on this Sukhumvit Line is at Asoke station (BTS) and Sukhumvit station (MRT).
The BTS skytrain Sukhumvit Line intersects with the BTS Silom Line atSiamsquare, the central shopping district of the city. The BTS Silom Line passes through the major business district of the city at Sala Daeng, where it links with the MRT (Silom station), and terminates at the Chao Phraya River, where there is connective service to the city’s public boat service (Saphan Thaksin BTS station – Sathorn Pier boat station). BTS skytrain extensions across the river and further down Sukhumvit are planned for the near future.
Unlimited single day and various multi-day passes can be purchased for both the BTS skytrain and MRT underground, many of which are ideal for tourists wishing to explore the city, though such cards are not transferable between the two independently owned rail lines and must be purchased separately.
