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
