Siemens to supply signaling technology for Dowtown Line extension in Singapore

The Siemens Spain Mobility division is to supply signaling technology for the planned Downtown line 3 (DTL3) extension in Singapore. The order, worth around €90 Mio, comprises the delivery of Siemens’ CBTC system for fully automated operations GoA4 in 2 new stations and one depot. The order also includes the Platform Screen Doors for the 2 stations.

The 2.2 kilometers Downtown Line 3 Extension, due for completion in 2024, will be connected with the Thomson-East Coast Line (TEL), providing commuters more travel options within the rail Singapore mass transit network.

The Siemens Spain Mobility division successfully commissioned the first 3 sections of Downtown Line (DTL) in Singapore last October, which is now considered the world’s longest suburban metro line fully automated.

The first section of the line, the DTL 1, with more than 4 kilometers, was opened in December 2013 and comprises 6 stations between Chinatown and Bugis. DTL 2, the second section, with 12 stations and 16.6 kilometers, connects Bukit Panjang and Rochor since December 2015. The third section of the line, the DTL3, with 21 kilometers and 16 stations, was commissioned in October 2017 and it is the longest section with 3 interchange stations in MacPherson, Tampines and Expo. With the opening of this new section, a significant improvement in the connectivity between residential and industrial areas is achieved.

The customer Land Transport Authority (LTA) awarded Westinghouse (today Siemens) in 2008 the contract for the supply, installation and commissioning of the signaling system for the DTL, which includes CBTC technology for the 34 stations and 92 trains, and the Automatic Train Supervision (ATS) system, Controlguide Rail 9000. Additionally, the project includes the installation of electronic interlockings Trackguard Westrace MkII and the supply of Platform Screen Doors.
