The MRT Yellow Line in Bangkok started passenger service on 19 June 2023. The Full Trial Run Opening Ceremony was attended by Prime Minister Prayut Chan-o-cha.
The Eastern Bangkok Monorail Company Limited, operators of the Yellow Line, had awarded Alstom the contract to supply the turnkey Innovia monorail system in 2017. Bangkok’s first driverless urban line features 30 four-car monorail train sets, fully-automated train control and integrated wayside railway systems. Alstom is also delivering the system for the MRT Pink Line, expected to enter service in 2024.
The project delivery, led by Alstom’s Turnkey regional hub in Bangkok, included system integration, installation and test and commissioning of the Innovia monorail trains, Cityflo 650 GOA4 driverless signalling, communication systems, power supply and conductor rail, track switches, platform screen doors and depot equipment. The Innovia monorail trainsets have been manufactured at the Alstom joint-venture CRRC Puzhen Alstom Transportation Systems Ltd. (PATS) in China. Alstom is providing 20 years of long-term maintenance for most of the systems provided and has mobilised a team of 170 services professionals to support the two monorail lines.
The 30.4 km long Lat Phrao – Samrong line services 23 stations and offers regular service between 06:00 and 21:00. Service is free of charge until 30 July 2023. The line runs entirely on an elevated alignment. The line interconnects with the Green and the Blue Line as well as with the City & Airport Link. A map is available here:
