Singapore’s Land Transport Authority and Siemens Mobility signed a contract to design and establish a simulation center for the Downtown Line’s (DTL) signalling system. The test center, which will be completed by end of 2020, will be located in Gali Batu Depot, where the DTL’s operation control center is housed.
The test center will include hardware similar to the rest of the system, including Westrace MKII interlocking, Trackside Trainguard CBTC System and radio network equipment as well as Rail9000 Automatic Train Supervision (ATS) System in depots and operation centres.
The test center will be established in two stages and completed by end-2020. The first will include ATS simulation environment and the second will include the full test environment including the CBTC, interlocking, communications and trackside elements.
The center will enable in-depth and faster technical analysis surrounding signalling-related incidents, enhance testing of new signalling features and system functionalities before deployment as well as increase capabilities for training LTA and the operator’s technical staff.
The Downtown Line is one of Singapore’s longest mass transit lines. With a length of 42 km served by 34 stations, the line connects Bukit Panjang in the north-west with Expo in the east
When its 2.2-km extension is completed in 2024, it will be 44 km long with three additional stations. The test center will enable testing and integration of the DTL’s signalling system before these three new stations commence operations.
The line is currently using Siemens Mobility’s signalling system and automatic train operations. The test center will be a digital twin of DTL’s signalling system, with capabilities to test key hardware interfaces.
It will digitally simulate these operations to eliminate any risks of service disruptions during system enhancements, troubleshooting, vulnerability checks, system patching, as well as allow testing of new software releases prior to deployment. It will also allow hands-on trainings and thus boost operations and maintenance competency.
