Boosting the passenger capacity of Bangkok’s metro

22 metro trains to serve the Green Line in Thailand's capital. The new fleet of additional trains helps residents of Bangkok to get around their city faster, while diminishing traffic jams and pollution.
Mobility for a world metropolis

Expanded mobility for one of Asia’s leading commercial metropoles

Today it’s almost unimaginable that until 1999, millions of people in Thailand’s capital relied solely on buses, motorcycles or taxis for urban transportation. To tackle the daily congestion in large areas of Bangkok, a master plan for rapid transit and mainline traffic was implemented. Its goal: to increase the use of public transport systems from 40 percent to 60 percent by 2021. To meet this ambitious target, Siemens has partnered with the metropolis in many ways - for example by designing and implementing the first three high-performance mass transit systems in the city.

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.

Metro trains for Bangkok

Efficient Green Line trains with more passenger capacity

The new four-car metro trains operate on the existing BTS (Skytrain) system and the Green Line extensions. With seats for 112 passengers and standing room for 1,460 at peak load, these trains help to boost the capacity of the lines to more than one million passengers per day. In late summer 2018, the first of the 22 four-car metro trains arrived at its destination in Bangkok. Since December 2019, all 22 metro trains are in passenger service.
“We have designed the train to optimize the passenger experience and to guarantee maximum throughput on Bangkok's Green Line."
Sabrina Soussan, CEO of Siemens Mobility Division

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
