Agenda • What are the drivers for change? • What do we mean by Modular signalling? • What has to happen to make this work? • What will happen in the future? • Summary & Conclusions

What are the drivers for change? Cost of signallers Cost of Signalling Cost of equipment Cost of projects Cost of ownership

What are the drivers for change? Cost of Signalling Changing technology Network comms ETCS Higher reliability Lower power usage

What are the drivers for change? Willingness to challenge standards Desire to reduce labour costs Ability to adjust railway easily Cost of Signalling ‘Green agenda’ Changing technology Changing attitudes Acceptance of technology Refusal to accept poor reliability

An example … ‘Green’ Low power ETCS compatibility usage an issue Life expired Maintainers! In-built condition Monitoring! Condition information and statistics not available remotely High levels of safety Low maintenance costs Expensive to operate Has to be operated locally Difficult to alter Extended service life

What do we mean by Modular Signalling? We consider a modular system to be one that displays the following characteristics: • Nearly all schemes can be delivered by selecting appropriate standard ‘modules’ from a small set of parts • Data only resides in one location • Modules can be applied in a wide variety of ways • All elements communicate over a network communications system • Any available power system can be used • Control is totally flexible, making the most of network communications • Reliability, Availability and Maintainability are key

Reducing Lifecycle Costs • Mobile technology extensively used in oil and gas industries • Wi. Fi, GSM, Bluetooth connectivity • RFID, Bar code readers • GPS

Reducing Lifecycle Costs • Appropriate use of Mobile Technology, Asset Management tools and Back office software allows – Asset database population from day one – Paper-free record keeping to reduce time on trackside – Appropriate enforcement of ‘signature’ and competence records – Access to information such as wiring diagrams – Standard test procedures to be adopted – Greatly enhanced maintenance through improved workflow management – Constant access to information such as reliability / availability statistics

What has to happen to make this work? • Changed attitudes – Contractor side – Client side • Challenging standards – without reducing safety – Specifically around civil structures around signalling principles • Standardisation and simplification of rules • Cooperation and collaboration between all parties • Open architectures and interfaces – to allow multiple suppliers to work on projects

What will happen in the future? • Addition of ETCS functionality – ETCS Level 2 requires • Eurobalise for location (LEUs would also be required for Level 1) • Addition of RBC to the network • Data changes at interlockings only • Control Centre additional functionality • Enhanced use of Mobile Technology • Mix and Match Control – can control railway from anywhere on the communications network • Reduction in fixed comms network, move to radio • Alternative power solutions

Summary & Conclusions • Modular Signalling is a reality • Invensys is contracted to deliver this technology to Network Rail • Many other infrastructure providers are opting to use this technology • This approach offers the potential to revolutionise the capacity and through life costs of secondary lines • Migration to ETCS L 2/3 is supported by the networked architecture • Many of the principles and approaches are easily applicable to all signalling schemes, of any scale or location • Standards need to be challenged, but intelligently • Technology and processes proven in other industries are the key to successful implementation
