The manual covers the design and installation of SSI onto Network Rail’s signaling infrastructure. It lists all approved documents relevant to SSI.
Purpose
This manual provides for the the safe design of Network Rail’s Solid State interlocking systems. The manual specifies generic data structures that are safety critical for this technology. Our approved suppliers apply these specific generic data design rules when designing the interlocking system. These generic data design rules prevent differing designers creating new solutions to the approved signaling principles that could import system safety risk to the operational railway (as specified within BS EN 50128 - ‘Railway applications - Software for railway control and protection systems’.).
The manual defines the generic hardware and software configurations of the system that permits signalling designers to comply with the relevant signalling principles.
The manual also defines the data design process and enables it to comply with the requirements of BS EN 50128.
