scope:

This guidance applies to the specification, development, review or enhancement of Adhesion Management Systems for lines which are being operated either manually or in Automatic Train Operation (ATO). It is of particular relevance to lines which are operated in ATO because the more intensive service on such lines is dependent on a higher level of adhesion than is normally the case on manually driven lines. It is therefore applicable to the following:

a) Definition, development, specification and implementation of the required Adhesion Management system to enable the introduction of ATO on any open section of the LU network

  • E.g. As part of a Line Upgrade when first implementing ATO

b) Review, modification or enhancement of an existing AMS when

  • Relevant assets are changed or significantly modified (e.g. new signalling, Automatic Train Control (ATC) or Rolling Stock)
  • A significant change is made to the line characteristics (e.g. extensive vegetation work, enhanced timetable, inter-running with another fleet)

c) The review, development, modification or enhancement of an existing Adhesion Management system due to unsatisfactory performance on a line. "Unsatisfactory performance" could mean:

  • An unacceptably high number of (signal or station) overruns in service
  • One or more unacceptably long overruns in service
  • An unacceptably high level of wheel damage (wheel flats or pitting)
  • An unacceptably high level of rail damage
  • Non-availability of a significant portion of the fleet due to wheel damage.

This document provides guidance on the best practice approach for achieving compliance with the associated LU standard S1189.

Purpose

The purpose of this document is to provide guidance to ensure a consistent and integrated approach when working to implement new or expand/modify an existing Adhesion Management System (AMS). This guidance covers:

a) A process and guidelines for determining AMS strategy and requirements, AMS selection and embedding the system into business-as-usual use,

b) Explanation of the reasoning for the technical content of the associated LU standard S1189 'Low Adhesion Management'.
