 System

The present Bangkok mass transit system comprises two different types of metros: 1) the elevated BTS system, the so-called Skytrain - rot fai fah in Thai, and 2) the underground MRT subway. Although BTS and MRT use similar technology (trains, signalling & train control), there is no track connection between them. All MRT stations are equipped with platform-screen-doors, which initially did not apply to any BTS station (in the meantime, the busiest have been retrofitted with half-height gates).

Besides the mass transit rail systems, Water Buses provide a fast transport service on the Chao Phraya River; at present, transfer to the BTS system is only possible at Saphan Taksin station.

   Green Lines (BTS-Skytrain)  

This is a completely elevated system built by Siemens as a turnkey project, opened in 1999, initially 23 km long with 23 stations. In 2021, the BTS system consists of two lines:
- Sukhumvit Line (51.2 km)
- Silom Line (13.2 km)

Track gauge is 1435 mm and power supply is via third rail at 750 V DC. The original 3-car trains were 65 m long (a fourth car was added to all trains between 2012 and 2013), air-conditioned and run at an average speed of 35 kph. Saphan Taksin station on the Silom Line was only planned as a temporary station, but as it offers an excellent connection to the Water Buses on Chao Phraya River, it remains open after the extension to Wongwian Yai, although the single-track section at Saphan Taksin station limits the capacity on the Silom Line.

 MRT Blue Line (BEM)

 

In August 1997 construction work began on this 21 km underground full metro with 18 stations; it finally opened for trial service in April 2004. In December 2001, Siemens was awarded the contract to build 19 three-car trains for this line and to provide the necessary operating equipment. This is an MRT line (MRTA) but BEM (formerly BMCL) is the operator via a concession contract from the MRTA.

A 1-station extension from Bang Sue to Tao Poon was eventually completed in Aug 2017 to create an interchange with the Purple Line.

The standard Blue Line station has an island platform on level -3. Sam Yan, Silom and Lumphini stations have side platforms on different levels, each with trains to Bang Sue on level -2, and trains to Hua Lamphong on level -4, whereas Bang Sue and Khlong Toei stations have two side platforms on the same level. Thailand Cultural Centre is much bigger than other comparable stations: the Blue Line stops on level -3, while level -2 is prepared to accommodate the Orange Line in the future. The surface Blue Line depot is connected directly to both Thailand Cultural Centre and Phra Ram 9 stations. A track connection between Blue and Orange Lines will be made via this depot.

28 km elevated line with 8 stations, standard gauge, from Phaya Thai via Makkasan/City-Terminal to Suvarnabhumi Airport, every 15 minutes, shared with special non-stop airport express which departs from Makkasan/City-Terminal, opened for commercial operation on 23 August 2010. After some years, however, the Airport express trains were discontinued, and the red trains now also operate as all-stops City Line trains.
