Delay Attribution Guide April 2011 Changes Ana Maria Sanchez Delay Attribution Board Administrator

1ST MARCH New Codes 4 new codes have been introduced to the April 2011 Delay Attribution Guide (DAG) CODECAUSE ABBREVIATION OW Connections held where the prime incident causing delay to the incoming train is a FOC owned incident and service is more frequent than hourly. - Check paragraph for likely situations. FOC CONN PS Cancellation of a duplicate or erroneous schedule. - Check Appendix A section P DUPE SCHLD X9 Points failure caused by severe snow where heaters are working as designed. - Check flowchart d for guidance in dealing with the impact of snow, ice or frost SEV SNOW XOExternal trees, building or objects encroaching onto Network Rail infrastructure (not due to weather or vandalism) EXT OBJECT

1ST MARCH XO Delay Code reasoning The new XO delay code has been introduced to reduce the use of XZ (generic external) for certain events such as:-  Trees falling from outside railway boundaries  Masonry / buildings (non railway) falling or threatening to fall onto the infrastructure  Motor Vehicles landing on infrastructure  Air borne ‘machinery’ landing on the infrastructure  Cautioning for potential external interference – e.g. cranes operating near to railway lines that could fall / drop  (In all circumstances the event must not be due to weather or vandalism which has defined coding in the DAG)

1ST MARCH KEY AMENDMENTS Section letter b Code JP. –Now reads: Failure to maintain vegetation within network boundaries in accordance with prevailing Network Rail Standards. This change has been made so that the DAG reflects the prevailing standards for vegetation maintenance regimes. Appendix A Section J – code JP has been edited to reflect the wording in section letter b Section flowchart – Did the animal originate from the train or from Railway Infrastructure (Non-Network Rail) –Railway Infrastructure has been added to remove any possible confusion which could lead attribution staff to include incidents where animals originated from fields.

1ST MARCH KEY AMENDMENTS Section – –The wording of this section has changed slightly and special attention should be given to the removal of the question marks after ‘other modes of transport have been affected. – Also note that the criteria for the severe weather warning must be issued by the Met Office but it must be relevant to the type of delay and the area in which the delays are occurring. The term ‘the effect of the weather is outside the design parameters of infrastructure and fleet equipment’ has been removed because, it was identified that it would be very difficult and not practical or useful to state what kind of effects would be constituted as being outside of design parameters of each asset for the purposes of Delay Attribution. It is still valid however to indicate that the effect of the weather must be unavoidable through maintenance. NoCircumstancesDelay CodeIncident Attribution f. Waiting passenger connections within the TOC/Network Rail connection policy, where the prime incident causing delay to the incoming train is a FOC owned incident.. YL Prime incident causing incoming train to be late at that point, if the connecting service is of hourly or lower frequency. If more than hourly frequency then separate incidents to be created attributable to Network Rail (OW/OQ**) Section (f)

1ST MARCH KEY AMENDMENTS References to Weather Management ‘RED alert’ and EWAT teams have been ADDED in order to have a nationally consistent trigger to start implementation of attribution to ‘external’ codes in exceptional conditions. The NCI approved Code of Practice ‘Section 7.1 Weather management’ is a cross industry procedure triggered by Route Control Manager Note that: All references to Rules of the Plan (or wording variations of the same document such as ROTP) now read Timetable Planning Rules All references to Rules of the Route (or wording variations of the same document such as ROTR) now read Engineering Access Statement.

1ST MARCH Any Questions? We encourage you all to visit the DAB website at: There you will find the latest copies of the DAG, FAG and competency standards. The web site is updated regularly with up and coming events and activities that the DAB are undertaking. You can use the website to obtain the forms to make proposals for change to the DAG and PDAC as well as requests for guidance. You can use the website to make suggestions on how to improve delay attribution on the whole. You can your representative via the website, however, please do not use this facility to request specific attribution guidance – the request for guidance process is to be followed in these cases. Feel free to the DAB Secretariat on: for clarification on process in regard to delay
