A successful approach to Solid State Interlocking (SSI) modernisation

Solid State Interlocking is a British design successfully exported to the rail networks of a dozen countries. In this paper, we review the benefits of improved design, in particular the use of open-standard communication equipment and centralised architectures against maintenance costs and system availability. Through the case study of the Belgian Railway Infrastructure Objectives, we demonstrate how the SSI installed base can be upgraded intelligently and without impact to revenue operations. In particular, we show how re-using the existing interfacing equipment to track products – and benefiting from a backward compatibility with the SSI data configuration – translates into a cost-effective migration path for asset owners and rail operators.
