Bangkok’s MRT Pink Line Commences Passenger Service

Bangkok’s MRT Pink Line has commenced trail operations, transporting passengers on an automated Innovia monorail system supplied by Alstom.

The Pink Line spans 34.5 kilometres and serves 30 stations, connecting the heavily congested Khae Rai to Min Buri. This service reduces the travel time between these destinations by 50%, with the journey now taking under an hour.

In addition, the Pink Line connects to five other rail lines in the city. By 2025, it will also serve an additional two stations to further improve the connectivity between Bangkok and Nontaburi.

The new rail service was inaugurated by the Prime Minister of Thailand, Mr. Srettha Thavisin, on 21 November and is now conducting free public trials until 30 December.

Once the trials have successfully concluded, the MRT Pink Line is scheduled to enter revenue service on 31 December.

It is operated by the Northern Bangkok Monorail Company Limited, who contracted Alstom to supply the turnkey Innovia monorail system in 2017.

Alstom also previously provided a monorail system for Bangkok’s MRT Yellow Line, which has been operational since July 2023.

Toby Tiberghien, Managing Director for East Asia at Alstom said:

“The inauguration of the Pink Line marks another critical milestone for Alstom in Thailand, as our second monorail system starts operation and showcases our expertise in delivering state-of-the-art mobility solutions.

“Through the Pink Line, we are proud to have supported our customer NBM and the Mass Rapid Transit Authority of Thailand (MRTA) in extending Bangkok’s urban transit network to new city areas. This accomplishment reflects our ongoing commitment to innovating for more connected and efficient urban transportation.”

The driverless monorail system on the MRT Pink Line operates at speeds of up to 80 kilometres per hour and can transport over 470,000 passengers daily.

Throughout the delivery of the project, Alstom installed, tested and commissioned the Innovia monorail trains, as well as the Cityflo 650 GOA4 driverless signalling, communication systems, power supply and conductor rail, track switches, platform screen doors and depot equipment.

The Innovia monorail trainsets were manufactured at the Alstom joint-venture CRRC Puzhen Alstom Transportation Systems Ltd. (PATS) in China.
