Train Radio System TRS5000

Train Radio System according Railway normative specifications with integraded transceiver

The TRS5000 sets a new standard in the modern railway communications industry and closes the gap between old legacy analog systems and the expensive GSM-R system technology.


The Train Radio System TRS5000 is a specialized radio communication system for locomotives, metro trains and light rail. It has been designed according to the specifications for railway environmental requirements as defined in the European standards EN50155 and EN50121-3-2, EN 50121-4 and provides the complete set of 3rd party certifications. As a result, it is a very durable and rugged train radio system with minimal space requirements.

The Train Radio System TRS5000 with its sub-components ZSE5000 as the central control unit and CoCo5000 as HMI is available in both, IP20 and IP65 ingress protection and can be mounted at critical locations within the rolling stock as well as in standard 19” (3HU) racks. The system uses an embedded TETRA mobile radio as RF front end. A configuration with one or even two CoCo5000 connected to the central control unit for double headed trains is possible. In railway networks the needs for equipment lifetime are much higher than for other markets. ErvoCom guarantees spare part support on PCB level for a minimum of 10 years after the system delivery.
