Rollingstock communications systems in the new digital era How Lantech Communications Global’s sub-communication systems offerings are resolving long held challenges for the rail industry.

EVICES IN RAIL environments must operate in harsh conditions, and survive severe air pollution, vibration, shock, input voltage ripple and surge. At the same time, operators are increasingly demanding more sustainable and costefficient solutions to connect all rollingstock sub-communications systems. These include train control and monitoring systems, digital displays and other passenger information systems, CCTV cameras, PA systems, and the passenger Wi-Fi systems that are increasingly becoming a necessity. Lantech Communications Australia, a joint venture partner of Lantech Global based in Taiwan, provides the networking (switch and router) infrastructure for these subcommunications systems. Lantech’s EN50155 switches solutions are adopted on rollingstock across the world, including the Sydney and Melbourne Metros, as well as the metro in Barcelona, Hong Kong, Amsterdam, Helsinki, German operator Deutsche Bahn’s networks and France SNCF rolling stock.

While current conventional train communication networks (TCN) are facing several challenges to improving services, Lantech Communications sales VP, Amanda Lee, tells Rail Express that Lantech is overcoming these. For example, one of the reasons Lantech’s solution for the Melbourne Metro was chosen over its competitors, according to Lee, is because of Lantech’s superior high frequency power conversion circuits that allow for DC-DC conversion into regulated 54VDC voltages inside the switches themselves for Power over Ethernet (PoE) operation. “The systems integrators wanted to use our switches, as all these devices are IP based and digitalised, they wanted the switches not only to be able to provide the data communications, but to also have the PoE functionality, which eliminates the need to have additional power for each
