Station layout

All the stations to the Skytrain are elevated. The platforms are built to accommodate trains of six cars, but trains of only three cars are in operation.

The first elevated level of the stations is accessed with stairs and often escalators, and contain the ticket booths, some small kiosk-like shops and access control gates. The second level (and third at Siam Station) is again accessed with stairs and escalators and contains the platforms and rails. Siam station is unique in the way that it is the only BTS station with island platforms, to facilitate transfer between lines. All of the other stations have side platforms. Additionally, many stations have ramps and elevators to allow wheelchair-bound passengers to access the ticketing hall and platform from the street. The distance between doors is equal throughout the train, regardless of whether they are in the same or different cars and the locations where the doors will be after the train has stopped are marked on the platform. For security and safety, security personnel are stationed at every platform and all ticketing halls.

Three Skytrain stations, Sala Daeng, Asok and Mo Chit, are interchanges with the MRT. Saphan Taksin station is connected to the adjacent Sathorn pier where the all Chao Phraya Express river boat services call. Many stations are linked by 'Skybridges' (overhead pedestrian walkways) to neighbouring buildings and public amenities.

Consumption of food or drink is forbidden past the ticketing gate or on the Skytrain.

Ticketing

For single-trip and store-value ticket holders fares are calculated according to distance, but adult / student / tourist passes for limited / unlimited train rides are also available. Next to the magnetic farecards, which require replacement once every two years, the Skytrain has adopted near-field contactless technology in its ticketing system, with the intent of becoming compatible with the system presently used in the MRT.
