Invensys Rail Dimetronic has started the dynamic tests of the first phase of the Downtown Line signalling project, a four kilometres section with six stations, facing its commercial commissioning next October with a completely unmanned operation.

The Singapore’s Land Transport Authority (LTA) awarded Invensys Rail the contract for the supply, installation and commissioning of the SIRIUS CBTC (Communications Based Train Control) system, Rail 9000 ATS (Automatic Train Supervision) system and associated signalling technologies for the Downtown Line in 2008.

Invensys Rail Dimetronic has been testing its signalling technologies in a test track in the Chinese city of Changchun since September 2011. The functional tests will be completed by the end of January 2013.

The beginning of the “test running” phase in Singapore will start next March, with the commercial operation of the first phase of the line expected in October 2013, with an unmanned operation under the supervision and control of the SIRIUS CBTC system.

The Downtown Line, which will have a total length of 42 kilometres, 34 stations and two depots, is expected to transport more than half a million passengers per day in a completely automatic operation (Unmanned).

SIRIUS is an Automatic Train Control (ATC) system which, among other advantages, allows the reduction of the interval between trains, increasing significantly the transport capacity of the line.

In the case of an eventual incidence, the SIRIUS system is able to continue operating thanks to its exclusive fall-back mode, based in a “speed codes” Automatic Train Protection (ATP) system, which allows maintaining the automatic train movement in a safety and completely automatic way, totally unmanned.

In addition, the project includes the installation of WESTRACE Mk2 electronic interlockings of latest generation; Invensys’ Rail 9000 automatic train supervision (ATS) solution and the supply of the Platform Screen Doors (PSD).
