Siemens Mobility and its consortium partners Bozankaya and ST Engineering Urban Solutions Ltd. have recently secured significant rail contracts in Thailand, including the Metropolitan Rapid Transit [MRT] system in Bangkok, which covers the Orange Line and Blue Line.
The contracts involve the delivery of 53 new trains, along with the installation of technical equipment for signaling and maintenance services. Additionally, Siemens Mobility has been tasked with expanding intercity connectivity in Northern Thailand through the double-track railway project from Den Chai to Chiang Rai and Chiang Khong.
These contracts mark a significant milestone for Siemens Mobility in Thailand. CH. Karnchang Public Company Limited and Bangkok Expressway and Metro Public Company Limited have been commissioning these projects with the goal of enhancing the efficiency, capacity, and sustainability of Bangkok’s public transportation network and Thailand’s mainline rail system. The various contracts will begin and conclude between 2024 and 2039.
“With over 30 years of trusted partnership in Thailand, we are delighted to continue to help Bangkok grow sustainably and shape travel in the country for generations to come. Our technology already reaches more than a million passengers in Bangkok every day, helping to reduce congestion and journey times. With 53 new trains, advanced signaling and telecommunication systems, and long-term maintenance services for the Orange Line, Blue Line, and mainline connections in the north of the country, even more people will be able to reach their destination quickly and emission-free,” said Michael Peter, CEO of Siemens Mobility.
Siemens Mobility to provide 32 new trains and integrated systems for MRT Orange Line
Siemens Mobility, in collaboration with ST Engineering Urban Solutions Ltd. and Turkish railway manufacturer Bozankaya, has secured a comprehensive turnkey contract for the Metropolitan Rapid Transit’s Orange Line in Bangkok. The contract involves the delivery of 32 three-car trains, along with the design, installation, and integration of mechanical and electrical systems covering a 35.9-kilometer route. The trains will serve both the east and west sections of the line, combining underground and elevated rail tracks.
The scope of work includes delivering rolling stock, signaling systems, communications, platform screen doors, and passenger information systems, ensuring a fully integrated and high-performance transport solution. The new trains are designed with modern technology, spacious interiors, robust air conditioning, and enhanced information systems for passenger comfort. Furthermore, Siemens Mobility’s energy-efficient solutions align with Bangkok’s sustainability goals, reducing the overall carbon footprint of the Orange Line system. Additionally, Siemens Mobility has been awarded a long-term maintenance contract for the Orange Line, ensuring reliable and smooth operations for years to come.
21 new trains and Enhanced signaling for MRT Blue Line
Siemens Mobility has secured a contract for the MRT Blue Line upgrade project to supply 21 additional trains and enhance the line’s signaling and SCADA systems. With a total length of 48 kilometers and 38 stations, the Blue Line is a vital component of Bangkok’s transportation network. Siemens Mobility has been involved in the line’s development since 2002, supporting its expansion and modernization.
Furthermore, Siemens Mobility will provide full-service maintenance for the additional trains as well as for critical systems such as rolling stock, signaling, communications, platform screen doors and power supply, ensuring the Blue Line’s efficiency and reliability until 2039.
Den Chai – Chiang Rai – Chiang Khong Line
Siemens Mobility has secured a contract to expand intercity rail connectivity in Thailand through the new double-track Den Chai – Chiang Rai – Chiang Khong project. The project comprises two segments, with the first segment covering the 132-km stretch from Ngao to Chiang Rai, including 11 stations. The second segment encompasses the 87-km stretch between Chiang Rai and Chiang Khong, with a total of seven stations. Siemens Mobility will deliver advanced signaling and telecommunications systems, including Centralized Traffic Control [CTC] and an Automatic Train Protection [ATP] system that complies with European Train Control System [ETCS Level 1] standards.
This signaling and telecommunications upgrade is part of a larger civil contract, which includes components such as the Trackguard Westrace MKII interlocking, Controlguide Rail9000 CTC/LCP system, ETCS L1, point machines, DC track circuits, and Clearguard ACM250 axle counters, with additional signaling components sourced locally. The majority of the engineering work will be conducted in Thailand, with support from Siemens’ experts in Spain, Australia and Germany.
