PGD2 – Reactionary Delay Attribution Examples This Process Guide contains explanations on how to allocate reactionary delays being a critical element of the attribution process. They are demonstrated with worked examples for what are considered the most common scenarios. PGD3 – Y code application This Guide was derived from the brief that supported the Y code changes for the April 2015 DAG. It contains descriptions of all the Y codes and examples of usage. PGD4 – Dispute and Resolution Process Guide This Guidance Process was designed for Operators and Network Rail Routes covering disputes and resolution principles to enable timely attribution and resolution. PGD5 – Delay Management TIN reattribution process This Process Guide was designed for the reattribution of Management TINs including appropriate actions and timescales. It sets out there needs to be a common understanding of communication requirements between parties. PGD6 – Joint Responsibility This Guidance Document sets out what does and doesn’t constitute Joint Responsibility and provides a reference table for the attribution of individual trains when joint responsibility criteria has been determined. Additionally it sets out some common examples of when Joint Responsibility does and doesn’t apply to aid understanding. PGD7 – Holding Code This guidance document sets out the appropriate use and processes to be applied by all Parties when considering an incident for Holding Code status. It prescribes what scenarios should and shouldn’t be considered for a Holding Code and covers the process to follow should a Holding Code be agreed PGD8 – Delay Allocation Entering and Leaving the network This guidance document covers various scenarios, in diagrammatic form, of delays caused to trains waiting to enter or leave the Network Rail network. PGD9 – Delay Allocation Managing Freight Services This guidance document covers various scenarios of freight trains retimed / rescheduled under the Managing Freight Services during Disruption (MFSdD) Control instructions and the attribution of any subsequent delays. PGD10 – Permissive Working This guidance document covers various scenarios relating to the process of ‘calling-on’ at stations and the relevant responsibility of each scenario. It particularly covers the principle that station staff communication with the Signaller is seen as acting as an agent to Network Rail in the same vein that a member of platform staff dispatching another TOCs service is seen. Delay Attribution Principles and Rules June 2017 Page Supp4 PGD11 – Queue of Trains This guidance document provides improved understanding on the allocation of delays for trains in a stationary (and moving) queue of trains. PGD12 – Uninvestigated and Unxplained This guidance document supports the amendments to the Z Codes (reclassification of ZW, ZX, ZY and ZZ and introduction of ZS and ZU) as well as the two new Delay Codes R8 and T8. It sets out the appropriate use of these Delay Codes, supported by process guidance in relation to the investigation and resolution of delays deemed unexplained or uninvestigated. PGD13 - Fatalities This guidance document supports and builds on PGD6 and specifically covers fatalities being an area cited by Industry as in most need of improved guidance supported with flow diagrams and further example incidents specific to fatalities.
