Siemens Mobility, in collaboration with consortium partners Bozankaya and ST Engineering Urban Solutions (Thailand) Ltd., has secured several significant rail contracts in Thailand.
These projects aim to modernise Bangkok’s Metropolitan Rapid Transit (MRT) system, expand intercity rail connectivity in Northern Thailand, and contribute to the efficiency, capacity, and sustainability of the country’s transport network.
MRT Orange Line: Integrated Systems and New Trains
Siemens Mobility will deliver 32 three-car trains for the Orange Line, covering a 35.9-kilometre route combining underground and elevated sections.
The contract includes the design, installation, and integration of critical systems such as signalling, communications, platform screen doors, and passenger information systems. Long-term maintenance services are also part of the agreement, ensuring reliable operations.
The trains will feature modern technology, spacious interiors, robust air conditioning, and advanced passenger information systems. This project supports Bangkok’s sustainability goals by incorporating energy-efficient solutions to minimise the system’s carbon footprint.
MRT Blue Line: Expansion and Upgrades
The MRT Blue Line will benefit from 21 additional trains and enhancements to its signalling and SCADA systems.
Siemens Mobility, which has supported the line’s development since 2002, will also provide maintenance services for rolling stock and other critical systems.
The 48-kilometre Blue Line, with 38 stations, is a key component of Bangkok’s public transport network.
Den Chai – Chiang Rai – Chiang Khong Line: Intercity Connectivity
Siemens Mobility will contribute to the development of the Den Chai – Chiang Rai – Chiang Khong double-track railway project, enhancing intercity connectivity in Northern Thailand.
The project involves advanced signalling and telecommunications systems, including Centralised Traffic Control (CTC) and European Train Control System (ETCS Level 1) standards.
The route spans two segments: the 132-kilometre stretch from Ngao to Chiang Rai with 11 stations and the 87-kilometre stretch between Chiang Rai and Chiang Khong with seven stations.
Siemens Mobility’s systems will enhance safety and efficiency, with much of the engineering conducted locally in Thailand, supported by international expertise.
These projects, commissioned by CH. Karnchang Public Company Limited and Bangkok Expressway and Metro Public Company Limited, reflect Thailand’s commitment to improving its rail infrastructure. They will enhance mobility, reduce congestion, and support sustainable development in both urban and intercity transport.
“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 signalling 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.”
