Train Maintenance Are the current methods fit for purpose Rail Safety Summit 2018 Simon Ellis Global Bids Support Technical Manager 01/11/18

Things have come a long way….. They are all wearing head protection! Simon Ellis | Bombardier Services | 01.11.18) | Rev. 1.2 |

Is Maintenance Fit For Purpose? What is fit for purpose? Fatalities and Injuries? Passenger or workforce fatalities in train accidents for the eleventh consecutive year* *Annual Safety Performance Report 2017-18 Simon Ellis | Bombardier Services | 01.11.18) | Rev. 1.2 |

Train Maintenance Practices Can our approach to maintenance be improved? Train Maintenance Approach Train Safety Staff Safety Simon Ellis | Bombardier Services | 01.11.18) | Rev. 1.2 |

How Technology Can Help – Minimising Risk Door Testing – Traditional Door Testing – Future Verify functionality & identify hidden failures Normally between 1 to 3 monthly checks Time at risk reduced to minutes Actual door health and data signals drives maintenance Minimising interference improves safety Can be delivered using existing data Simon Ellis | Bombardier Services | 01.11.18) | Rev. 1.2 |

How Technology Can Help – Assisting Technicians Tooling Human eye is powerful However is it always the best tool? How accurate can we measure? Repetitive Tasks Functional checks Checking of dates Maintenance Information High reliability reduces frequency of carrying out replacement tasks Highest risk to fleet safety is when systems replaced / repaired Next generation of techs from the ‘You Tube’ generation Simon Ellis | Bombardier Services | 01.11.18) | Rev. 1.2 |

How Technology Can Help – Maintainer Safety Reducing Exposure – Heights Working at heights a significant HSE issue on depot Technology can minimise the need for such exposure Significantly reduces operational and safety risk Reducing Exposure – 3rd Rail 3rd rail exposes significant electrocution risks Automated Visualisation reduces potential for exposure Will robotics have a future?

Train Design / Depot Design ‘Design For Maintenance’ improvements critical Some can be very simple – closed and locked visualisation Good train design minimises the risk of maintenance induced errors Depot Design Plays an equal and critical role Improving maintenance environment: Enhances staff safety Enhances the maintenance carried out on the train Simon Ellis | Bombardier Services | 01.11.18) | Rev. 1.2 |

Conclusion Train maintenance is delivering strong safety performance to date but improvements can be made Future technology can be an enabler to help strengthen this performance further Design for maintenance can enhance both the train and depot design to further improve safety of the staff and train These improvements can also help deliver maintenance in a more efficient and effective manner Simon Ellis | Bombardier Services | 01.11.18) | Rev. 1.2 |
