The BTS Skytrain has two lines – Silom and Sukhumvit. The BTS Skytrain is different from the Airport Rail Link and Subway (MTR or Metro Rail as others would call).
The Silom Line (west-south route) runs from The National Stadium to Wongwian Yai and has 9 Stations as follows:
The National Stadium (W1) has direct access to MBK Shopping Center. MBK is one of the largest shopping malls in Bangkok. Also near the National Stadium Station is Bangkok Art and Culture Center.
Siam Station (Central Station) is the center of everything that is Bangkok. Siam Paragon, Siam Discovery and Siam Square are accessible from this Station. Also nearby are Siam Ocean World, Madam Tussauds Wax Museum, CentralWorld Shopping Complex and some posh hotels like Centara Grand and Siam Kempinski.
Ratchadamri Station (S1) is the gateway to Bangkok’s luxurious homes, hotels and malls. Lumpini Park and Erawan Shrine are here. The famous Four Seasons Bangkok, Marriot Courtyard and Anantara Baan Rajprasong are all here. For luxury shopping, Peninsula Plaza and Gaysorn are nearby.
Sala Daeng (S2) is the nearest station to where I normally stay in Bangkok. This station is the gateway for Silom and Patpong Night Market. Around are clubs, pubs and bars and of course the sinful “upstrairs” shows. Dusit Thani Hotel and Pan Pacific are just nearby.
Chong Nonsi (S3) is in Sathorn Road and has a nice view of Bangkok skyline. Nearby are Salaisap Market famous for outdoor shopping and street foods.
Surasak (S5) is where the only Indian Temple in Bangkok is – Sri Mariaamman Temple.

Also accessible from this station are Shangri-La, Center Point Silom Hotel and Bossotel Bangkok among other hotels in the river banks.
Krung Thon Buri (S7) is on the other side of the Chao Phraya River and is mostly residential. There is not much to see here except the river. Hotels nearby are Hilton and Peninsula.
Wongwian Yai (S8) is also residential area. King Taksin Monument is here.
I wonder why there is no S4 Station

Saphan Khwai Station (N7)has not much to offer except the local shops that sell second hand items and goods.
Ari Station (N5) is a residential area for high rise condos and expensive restaurants.
Sanam Pao Station (N4) not much to see except high rise buildings which I presume are offices.
Victory Monument Station (N3) is where the Victory Monument is as well as Phya Thai Palace, World War II Park, and Bangkok Doll Museum. King Power Duty free is also near here as well as the Victory night market

On Nut Station (E9) is also a residential area and Tesco Lotus Hypermarket is just within the station.
I wonder why there is no N4 Station
It is a good decision to stop at all train stations, get down and have a little walk to see what it has to offer. A great and inexpensive way to explore Bangkok is through the Skytrain and its subway.
