The Mass Rapid Transit Authority of Thailand (MRTA), Bangkok Expressway and Metro Public Company Limited (BEM) and Karnchang Public Company Limited have officially implemented full passenger revenue service for the Bangkok Blue Line Extension. The Blue Line Extension has added a length of 28 km with 19 new stops and 35 three-car trains. With this extension, the Blue Line can accommodate around 500,000 passengers daily. The Blue Line links the Thonburi side of the Chao Phraya river to the other parts of the city. Supporting this project, Siemens Mobility has carried out the integration of turnkey services for the 35 metro trains, installed signalling, constructed the traction power supply and developed a passenger information system.
