10 Operation - general Operating staff 2 Signallers and 1 Control Centre Technician on duty in Signalling Centre Maintenance staff for route based centrally at Machynlleth with technical support from Shrewsbury Uses new Rule Book for ERTMS operation Includes use of written orders Route barring for possessions Brand new procedure for ESR/TSR management GSMR voice communication Date

11 Operation engineering work New ERTMS rule book introduced new trackside access rules New track safety rules & competencies required for staff New engineering planning access rules required Engineering trains require ERTMS pilot loco to access site Transition between ERTMS and conventional required special access rules Staff required GSMR radios for communications trackside Date

12 Operation engineering work Management of Metrication Asset management processes in imperial measurement Cambrian linespeed metric Processes required to manage the difference so no safety impact when asset protection speeds required Management of TSRs/ESR Direct implementation of speed restrictions by Signaller No need to access track to implement speed restrictions New processes developed for planning, operations and maintenance staff Date

13 Maintenance Control Centre Technician on duty 24 hours a day Carries out maintenance of control centre equipment Carries out route barring process for possessions Supports the Signaller in the management of TSRs/ESRs Liaises with outbased maintenance staff Coordinates infrastructure data for the DRACAS process Leads fault finding across the route Date

14 Management of change New processes required to understand the impact changes will make on the system Linespeed changes Data changes required, Degraded mode Signage requires review, driveability of speed profile requires review Technical file for RBC requires update New fleet of trains to run on the line New keys require issuing impacting trains and RBC Major infrastructure change Formal update of technical file by NoBO & reauthorisation by NSA required.

18 Issues arising from pilot operation Management of speed profiles across the route Management of gradient data Management of SPADs/ EoA breaches Reliability and availability of the FTN system Effective working relationship between Signallers and Drivers Closer working relationship between infrastructure maintainers and train maintainers Sharing of data from infrastructure and onboard systems Date

19 Lessons learnt Importance of managing ERTMS implementation and operation as a System Require a team of Operators (infrastructure and trains) and Engineers (infrastructure and trains) Criticality of understanding the operational concept before commencing engineering design Understanding that a minor change trackside can have a significant impact to the operability/driveability of the train Criticality of managing reliability growth from a systems perspective with a comprehensive DRACAS system Date
