GSM-R terminals on the train
SVR-400 cab radio (International)
The Siemens SVR-400 is fully compliant with current EIRENE specifications and can be customised to suit specific railway requirements and operates in a vast range of environmental conditions. It provides safe and secure communications in the standard GSM-R band of 900 MHz and alternatively in the special 1800 MHz bands. It can be installed with either one or two remote driver control panels, has a unique gland box system allowing fast installation and replacement, and an optional uninterrupted power supply unit providing either 2 or 4 hours back up power in the event of train power supply failure. With a demonstrated MTBF in excess of 83,500 hours it minimises downtime and total lifetime costs.
SVR-401 cab radio (GB)
The Siemens SVR-401 has been specifically developed for the British market. It is fully compliant with current EIRENE specifications and includes all the required features for railway operation. It provides safe and secure communications in the standard GMS-R band of 900 MHz between signallers, train drivers and other operational staff across the whole of the network. It is designed to be installed with either one or two textual driver control panels, has a unique gland box system allowing fast installation and replacement, and an optional uninterrupted power supply unit providing either 2 or 4 hours back up power in the event of train power supply failure. With a demonstrated MTBF in excess of 83,500 hours it minimises downtime and total lifetime costs.
SVR-455 cassette radio
The Siemens Voice Radio (SVR) range, whilst fully compliant with current EIRENE specifications, can also be customised to suit specific railway operational requirements. As part of a unified GSM-R radio system, it provides safe and secure communications between signallers, train drivers and other operational staff across the whole of the network.
The SVR-455 is a compact cassette mounted radio with an integral graphical MMI and loudspeaker. The cassette is installed in the driver’s cab and the radio simply slides in.
The GSM-R tranportable cab radio is a self contained unit consisting of a GSM-R radio complete with a textual MMI, handset and loudspeaker in a robust case. The transportable cab radio is designed to be easily carried between trains and installed with the minimum of effort and expertise. It can be used as an emergency backup or in trains that do not have a cab radio permanently installed.
The Siemens SGR-200 GPRS data radio enables the transfer of packet switched data over the GSM-R network. It allows high speed data to be transferred to and from the train without restricting calls to and from the voice cab radio. It contains a single radio transceiver, one operational antenna port and train power supply interface, and providing data communications between the GSM-R ground system and on board computer through GPRS packet switching. It is housed in an aluminium case providing durability and strength. It meets the EIRENE onboard environmental requirements.
The Siemens SDR-200 ETCS on board data radio provides an important link for the transmission of movement authorities from the Radio Block Centre (RBC) to the train where an in-cab display allows the driver to control the train without reference to line-side signals. The radio is a compact unit designed for ease of installation with ETCS equipment from other suppliers. All of the main components within the data radio are fully duplicated to provide the necessary high availability required for the application.
Graphical drivers control panel
The Siemens graphical drivers control panel (or Human Machine Interface) was designed to take account of environmental, size and ease of installation. It includes an integral loudspeaker and features a colour TFT (Thin Film Transistor) display and illuminated pushbuttons enabling clear uncluttered communications to the driver. The Illumination and key back-lighting intensity is set by the driver, with automatic compensation control based on external ambient light levels. The backlit display also provides a wide viewing angle. Legible high display resolution allows any character set to be presented, e.g. Turkish, Greek, Arabic and other typography.
Textual drivers control panel
The Siemens textual drivers control panel (or Human Machine Interface) is one of the smallest available on the market. Interactive dialogues between Siemens design engineers, drivers and human factors groups resulted in a driver’s control panel layout that is both intuitive and non distracting, making it easy to use. Drivers experience positive tactile feedback, confirming that the desired button function has been achieved.
The safe and cost effective way of reducing public band interference is to employ the latest on-train filter technology. The filters are designed with the optimum combination of size and performance, which permits easy and low cost fitment of the filter to both new and existing GSM-R installations. The filter is simply inserted in line in the RF cable between the radio and the antenna. It can be mounted directly on the train structure or via an adaptor plate.
