/8-May-151 Signalling - Safety Step Up System Safety in the delivery of Signalling Projects To be delivered as ‘safety conversational’ and discussed within a Step Up environment 1 st – 12 th December 2014 ## Please delete this slide for onward brief ##
/8-May-152 Signalling - Safety Step Up Conversation System Safety in the delivery of Signalling Projects Delivery Lead & Lead Engineer names
/ 3 Signalling Projects Safety Working Group Background & Timeline A number of system safety issues encountered on signalling projects over the last 5 years. Supply chain members’ concerns were raised with the Railway Industry Association (RIA) and the Institute of Railway Signal Engineers (IRSE) in mid 2013 and mapped to investigation causes. These parties with NR IP met to discuss the concerns in October A working group was convened under auspices of the IRSE Council, and incorporated a wider representation of the rail supply industry. This group under the banner of the IRSE made recommendations in June 2014.
/ The IRSE and Industry Recommendations….. 8-May-154 Build upon the use of technical stage-gates already developed for data in signalling systems, to be applied to all signalling projects, with any non-compliance to this requirement being very much the exception to the rule and treated with the seriousness it deserves If the agreed date for passing a stage-gate (financial or technical) cannot be met, the implications (including safe assured delivery) for the planned commissioning date(s) and other critical milestones must be identified, risk assessed and mitigations addressed Any change to the agreed/approved specification during the detailed design, construction, testing and commissioning phases should be avoided. Where change is absolutely necessary, both supplier and client must be in agreement that the impact of the change can be safely managed. The non-sequential application of signalling design/development processes should be the exception, not the norm and when utilised shall be subject to formal risk assessment. Rigorous change control processes must be applied to all designs issued for construction purposes (and not just AFC designs).
/8-May Projects need to be developed in a manner that enables and secures safe and efficient delivery. 2.Initial bolt down of scope. 3. Managed approach to change, the assessment of time and process impact and the reduction of technical risk. What we have to ensure….. 4. Whenever the process is impacted, a reassessment and any necessary reduction of technical risk.
/8-May-156 The Network Rail Safety Vision Statement… The CEO’s Safety Vision Statement #3: We will plan work to ensure that it can be done safely. #8: We will relentlessly strive to find new ways to keep ourselves, colleagues, passengers and the public safe. #9: We will design, construct, inspect, operate and maintain the railway to keep everyone safe. The context of the necessary actions….
/ Planning & Integration… 7 8-May-15 - Integrated Plans - Include ALL Disciplines - Includes all stage gates at a timely point before the end of that GRIP stage - Include Inter Disciplinary Check - Realistic & durations confirmed by stakeholders - Sequential Working

/ An example of a Technical Stagegate Checklist… 8-May-1510 Image Slide Deliverable / Check ItemEnd of GSStagegate OutputPurpose Operational Requirements Specification 1Pass / Fail - escalateThe purpose of the Operational Requirements Specification is to provide a detailed and final definition of the Operations stakeholder‘s requirements. (To also include List of Routes) Project HAZID1Pass / Fail - escalateProject HAZID to include but not limited to compatibility with rolling stock, duty of co-operation (ref GE/RT8270) Design Decision Log1Pass / Fail - escalateThe purpose of the design log is to record all relevant decisions on the project to create an audit trail for the evolving design. Review level of complexity and interlocking capability 1Low – No action Medium / High - escalate Review the level of complexity and capability for the technology proposed and to be altered for risk. Are sufficient resources available How easily can the system be altered Can the system deliver the required outputs Review Non Sequential Activities1Low – No action Medium / High - escalate Review the risk imported or to be imported due to non sequential activities already taken place or those planned to take place during the next phase. Review current status of source records 1Low – No action Medium / High – escalate Review the availability of source records to allow this scheme to move forwards. This shall also include the current status of the signalling deficiency register.
/8-May-1511 The Common Safety Method – Risk Evaluation and Assessment Flow Chart HAZID Risk Evaluation & Assessment For scope changes and before introducing non sequential working identify risks and controls using this established process.
/ What to consider about your project works as you return to the workplace… 8-May Is the scope fixed and understood? 2. Have you and are you managing the risk from change? 3. Recognise non-sequential working, assess the imported risks to safe delivery & control… AND… Are you in a fit state to progress?
