Live CBTC trial launched on Singapore’s North-South Line
Singapore’s Land Transport Authority (LTA) and SMRT have begun operational trials of a new CBTC signalling system on the North-South Line (NSL). Testing is taking place with the new signalling system, which will replace the existing fixed block signalling system, in the final hour of service. Using CBTC signalling, headways between trains will be shortened […]Intelligent power converters
To operate lighting, electronics and communication devices, both on trains and in control rooms, power converters such as inverters, battery chargers and power supplies are often installed to convert available DC or AC to the appropriate power outputs required. Complicating matters, both the power source (DC in varying voltages from battery banks) and the outputs […]East London Line Tunnel Emergency Control
