An Australian first: a new generation interlocking for the Hornsby project

Any new interlocking technology is a major investment for both the customer and the supplier. The customer's investment is often underestimated, particularly the residual value of their historical investment in earlier technologies. For the supplier, safety critical developments of this type are extremely expensive. Strategies are needed to make those developments as cost effective as possible, both initially and through the extended support phase. WESTLOCK is a new interlocking technology that meets both these challenges. It builds on the existing investments in SSI infrastructure, assets and skills, so that their value is maintained. Projects, particularly where existing SSI based systems are used, are made cheaper and quicker to deliver. WESTLOCK builds on an existing proven product, TRIDENT, and reuses existing signalling concepts and components to reduce long term support costs and provide an optimum mix of proven technology and innovative features. The Hornsby Station and Platform 5 Stabling Project was an ideal application for this technology, taking advantage of all its key features. It is also the first commercial application of WESTLOCK anywhere in the world.
