ErvoCom has been commissioned to completely renew the TETRA on-board train radio system of Dublin’s LUAS light rail network. The TRU25 central control unit in conjunction with two HMI’s COCO2167 at either train head replaces the existing system entirely, ensuring future-proof voice and data communication across the entire network. A key component of the project is the central control unit TRU25, developed to precisely align with LUAS’s functional specifications and ensure full interoperability with current vehicle and infrastructure interfaces. After successfully delivering and commissioning the TETRA train radio dispatcher at the Operational Control Centre (OCC), ErvoCom was once again chosen to supply the new train radio systems, a result of strong customer satisfaction and continuous innovation.
