Expanded mobility for one of Asia’s leading commercial metropoles
In May 2016, Bangkok Mass Transit System PLC (BTSC) placed an order with a consortium comprising Siemens and the Turkish public transportation vehicle manufacturer Bozankaya for the delivery of 22 four-car metro trains. In addition, Siemens will be responsible for their service and maintenance for 16 years.
The project follows the successful delivery of 35 three-car units for Bangkok’s first metro, Skytrain, in 1999. Another contract for 19 three-car units was awarded to Siemens in 2002 for the new MRTA metro system in Bangkok. And to increase system capacity, Siemens was commissioned in 2009 to extend the three-car units of the Skytrain by inserting an additional intermediate car.
Efficient Green Line trains with more passenger capacity
We have designed the train to optimize the passenger experience and to guarantee maximum throughput on Bangkok's Green Line.
Highlights for the Green Line
The Siemens scope for the Green Line extension trains includes the bogies, traction and braking systems, and auxiliary systems as well as the project management, development, construction, and commissioning of the trains. The trains manufactured at the Bozankaya factory in Ankara, Turkey, provide:
- Reliable operation – thanks to proven technology and high redundancies in the traction system; one converter drives two motors
- Improved maintainability – optimized, based on Siemens’ long-term experience in Bangkok
- Low-wear mechanical brake and high stopping accuracy – thanks to dynamic braking to standstill
- Reduced energy consumption – thanks to a lightweight stainless-steel car body, state-of-the-art traction technology, and interior and exterior LED lights
Prepared for a modern and growing metropolis
Expanded passenger capacity
The interior design not only offers a spacious and inviting ambience, but will also increases passenger capacity compared with predecessor vehicles.
Optimized passenger flow
Four electrically powered 1,400 mm-wide external sliding doors are arranged on both sides of the cars to allow passengers to board and leave the train rapidly, reducing the time the trains spend in the stations and increasing system capacity. The coloured floor distinction between entrance and seating/standing areas simplifies the orientation for passengers, and also improves the passenger flow.
Enhanced passenger comfort
The passengers’ comfort is enhanced through an extremely effective high-performance air-conditioning system, which responds to weather conditions, prevailing high temperatures, and humidity levels. An innovative air diffuser system provides an efficient and comfortable air supply, while also preventing water condensation.
High safety level
The new metro trains comply with the latest safety standards according to EN 50126, 50128, 50129 and IEC 61508 as well as fire safety requirements according to NFPA 130/EN 45545.
