GE Transportation SSC Automatic Train Protection GE Transportation s SSC Automatic Train Protection delivers safe cost effective operation and easy installation without changing driving rules This advanced train protection system offers an innovative and unique design on track to train data transmission for train control Unlike other solutions deploying GE Transportation s SSC Automatic Train Protection does not require devices or cables mounted in the track area Its wayside components are mounted line side deriving their power from the existing signals eliminating the need for new power cables Consequently installation on an existing infrastructure is simple and quick with minimal traffic disruption SSC Automatic Train Protection is an overlay spot train protection system that uses microwave technology to transmit signal and track information to the train By enforcing them SSC Automatic Train Protection can maintain the existing operating rules without requiring a massive re training of railway staff Its modular design also allows optimizing the line s performance while improving safetu GE imagination at work SSC Automatic Train Protection Components This system has two main components wayside and on board units The wayside subsystem is overlaid on the existing infrastructure and is designed to minimize installation costs and deployment time Safe track to train transmission o
3. ccurs at signal locations via a low power microwave channel The SSC Automatic Train Protection s on board unit equipment is a fail safe supervision system with minimal impact on the driver s operations Wayside equipment Wayside components are installed at the side of the line typically one unit for each signal of the infrastructure The wayside consists of one encoder and one transponder antenna both with very low power consumption allowing them to safely be powered by the signal lamps The wayside equipment including the transmission device i e transponder can be installed entirely on the signal pole reducing costs for installation eliminating the need to stop traffic for both installation and maintenance and increasing vandal resistance The wayside transmits the signaling Status to the on board unit through microwave track to train link At each point of information SSC Automatic Train Protection provides the applicable speed level for the line stretch after the signal On board equipment SSC Automatic Train Protection s on board equipment continuously ensures the movement authority is enforced with respect to the signaling status and speed information received from the wayside Otherwise the driver receives a warning and ultimately braking is enforced if the train driver fails to obey the warning Train braking is also enforced when a signal at danger is passed SPAD protectio
4. n The on board also checks if any track to train transmission is missed due to a distance based linking function SSC Automatic Train Protection s on board unit is fast and easy to install and maintain with no device mounted under the rolling stock GE imagination at work Radio infill The system s innovative radio infill function augments the performances of the discontinuous automatic train protection It guarantees e Required running capacity e Maximum speed limits applied even in those stretches of lines with impaired visibility e g excessively short visibility distances e Prompt reaction to signal aspect change The radio infill function can be limited to those signals that require continuous information to the train in advance so there is no need for full radio coverage of the line Standards compliance GE Transportation s SSC Automatic Train Protection complies with the most recent and demanding European standards CENELEC 50126 50128 50129 and 50159 SSC is CENELEC SIL 4 Environment CENELEC 50125 50155 trackside part designed to 40 C to 85 C range To learn more visit www getransportation com GE the GE Monogram imagination at work ecomagination and all other trademarks and service marks unless otherwise noted are owned or licensed by General Electric Company or its subsidiaries All other brand names product names or trademarks belong to their respective holders
