2 Activities Object Condition-Based Maintenance Chain Monitoring Before Data Analysis Measure of: Track, Rail, Ballast, Overhead Line, Switches & Crossing, etc. Critical defects Detection Defects Validation and localization of data & Alert generation Scheduling Execution Single and Degradation cross/multiple RAMSYS Speed and Work parameter analysis History Analysis Closing out the Checking Line Issuing Work Work Order with Quality Index Availability and Clustering of Calculation Orders technical Resources Works (location, ) and Defects List Allocating economical Setting Production of Generation Resources (labor hours) Priorities System Scenarios information Issuing Alerts Maintenance and Renewal (M&R) Works Planning Today Optimisation Maintainability Maintainability aintainability Control KPIs Efficiency Efficacy Results Measurements/ Ispections/ Critical Defects Structured Data Alerts/Defects Railway Railway Reliability Reliability eliability Asset Asset Availability Availability vailability Safety Safety afety System ailway Scenarios Management Management Optimised Scenario Scheduled Work Order Building Work History M&R Actions and Policy Change Systems Measuring and Video Inspection Systems Asset Manintenace Management Systems Decision Support Systems Enterprise Resource Planning (ERP) / Enterprise Asset Management (EAM) 2

3 RAMSYS Benefits Reduction / minimization of Accidents (e.g. derailments) Taking Control of Dynamic forces => extension of asset service lives Shifting from Corrective to Preventive Maintenance, i.e. acting BEFORE defects have occurred Reducing defects/damages Minimizing Traffic Disturbances & Speed Reductions Allowing time for Planning and Resource Allocation Optimization Enabling What-if analysis, i.e. the ability to test different Maintenance Management Policies & Strategies 3

4 Railway Infrastructure Asset Management Systems Measurements Inspections Planning RAMSYS Work History Asset Inventory Costs Types of data to be collected for Computer-Aided Railway Infrastructure Asset Management Systems 4

5 Integrated Condition Measurement Track Monitoring Track Geometry Rail Profile Rail Corrugation Overhead Line Monitoring Overhead Line Geometry (static and dynamic) Contact Wires Wear Catenary/Pantograph Interaction Electrical Arcs Electrical Parameters (Voltage and Tension) Ride Quality Instrumented wheels for Wheel/rail interaction forces Body and axle-boxes accelerations Wheel-Rail Contact Geometry ARCHIMEDE Measuring Systems Telecommunication Monitoring GSM, GSM-R and ETACS monitoring Signaling Monitoring Monitoring of coded currents in the track Auxiliary Systems High Accuracy Positioning Systems (Encoders, Doppler radar, Transponders, Passive Milestones Laser Readers, Differential GPS) Video Inspection of Track, Wayside and Overhead Line Optical Fiber Communication Network 5

6 Diagnostic Systems TRACK GEOMETRY Measuring System Measured Parameters: Track gauge Rail right/left longitudinal level Rail right/left alignment Cant Twist on settable basis Curvature Radius Technology: opto-electronic devices (high speed cameras and lasers) using chord base principle Sampling Distance Measuring Speed 25 cm from 0 to 300 km/h 6
