Derailment Reduction Strategy Proactive Leadership & Guidance

Presenter: Kirsten Alexander General Manager, Services & Contracts ARTC

Date: 29th April 2014 Location: Sydney

Introduction •  This presentation will cover the following:

•  Improvements made to management of Rail Stability •  Rail Reliability strategy and future directions •  Wayside Strategy and progress in derailment reduction •  Development of the Central Condition Monitoring Database to further

aid analysis and trending of rolling stock condition issues

Track Stability – The Past & The Present Welded Track Stability Analysis (WTSA)

•  Labour intensive •  Gave Team Managers a % value for stability loss •  Specific timeframes for rectification •  Significant assumptions (rail installed at design SFT)

Track Stability – The Present

Hunter Valley

Track Stability Management Plans (ETM-06-06)

•  Inspect, Assess and Act •  Identify “Special Locations” •  High Temperature Requirements

Track Stability – The Present Challenges

•  Specific focus on Special Locations – risk based approach

•  Loss of industry knowledge and associated training

•  Competent operators of SFT devices (Verse & Railframe)

Track Stability – Further Improvements (14/15) •  Identify Baseline Special Locations Map

–  Using configuration data determine locations where Special Locations exist on the network

–  Team Managers can then build on this for the TSMP

•  All Special Locations to have SFT Measured –  Requires more personnel to be trained in

using SFT measuring devices –  Program to be submitted to DM and

compliance to program measured •  Management Reporting

–  Develop reporting tool for Track Stability utilising the Asset Management system as the data receptacle

Hunter Valley Rail Strategy •  A strategy overview of rail reliability management

•  Customer Focused approach •  Data analysis

•  Identification of higher risk areas

•  SFT Measuring –  ARTC Standards Department working

with a number of suppliers to Type Approve non-destructive SFT testing devices

–  A quick, simple and accurate SFT measurement is the ultimate goal

•  Predictive System Trials –  Technologies exist that can measure

rail stress as specific locations –  Investigate installing at high risk

special locations

Future Directions for Rail Management

ARTC Wayside Strategy •  This part of the presentation will deal with risk mitigation from use of

Wayside data collected from the following systems: •  Wheel to Rail Impact and ‘approximate’ Axle Loads - WILD •  Acoustic Measurements of Bearing Condition - RailBAM •  Measurement of Wheel Squeal & Flanging Noise - RailSQAD •  Wheel Set Angle of Attack and Hunting - TBOGI •  Wheel Profile Measurements - Wheel Profile

•  Systems located in consultation with industry Wayside Steering Committee (ARTC and Customer Representatives).

•  Overall aim of wayside strategy is to reduce the risk of damage to above and below rail infrastructure.

Central Condition Monitoring Database •  The purpose of the CCMD is to collate disparate data into a single

database allowing correlation of measurements for each vehicle, for the purpose of measuring rolling-stock performance trends. •  WILD - Wheel Impact and Load Detector (TrackIQ Pty Ltd.) •  RailBAM - Bearing Acoustic Monitor (TrackIQ Pty Ltd.) •  RailSQAD - Wheels Squeal Acoustic Monitor (TrackIQ Pty Ltd.) •  TBOGI - Wheel Angle of Attack & Hunting (WID Inc. Canada) •  TrainBase - Wheel Profile Measurement (KLD Inc. USA)

•  As each train transits the ARTC network and passes a wayside data collection point, data is collected from one or more systems.

What does the CCMD do? •  Reprocesses the original Sensor Data captured in the field •  Recalculates performance values as part of the pre processing •  Examines the data for correctness and relevance (data cleansing) •  Aligns the data with the ARTC Vehicle Registry •  ‘Mates’ sensor records for the same train into one composite record •  Summarises, compresses and stores the data into a single database •  Exports the data by Customer, to a set of XML Files

Wayside Data Issues Prior to CCMD

•  The original data sources are largely incompatible with each other •  Data is only available from individual web portals •  Data can only be viewed in ‘read only’ fashion •  Downloading data is very difficult and restricted (spreadsheet) •  Two of the sites are in North America (slow to refresh) •  Any additional sensors will increase data integration complexity
