    1. Module 12:Track Inspection & Maintenance

    2. Objectives Track Inspection • Importance of Track Inspection • Methods and Types of Inspection • Application of the Track Safety Standards • Specialized Inspection Vehicles Maintenance Practices • Preventative Maintenance • Typical Activities • Production Activities • Integration of Maintenance in Design

    3. Importance of Track Inspections • FRA / Transport Canada Required • First and Last “Line of Defense” against track related derailments • Initial phase of planning for maintenance activities and future track upgrade programs • Public and employee safety

    4. Inspection Methods • Hi-Rail Inspection • Walking Inspection • Train Inspection

    5. Inspection By Hi-rail • Hi-Rail • The hi-rail is a versatile vehicle that allows the inspector to traverse the track in one direction and return by road • Provides flexibility/versatility • Most common method utilized for scheduled and special inspections • Most often one, and sometimes two Inspectors observing the track • Scheduled per regulatory requirement and/or company policy • Visual detection of defects • “Feel” and sound of the track that may indicate the presence of a substandard condition

    6. Walking Inspections • Allows for a more detailed look at the track. • Quantify defects with physical measurements • Planned at various times of year, or; • Company policy may dictate an annual walking inspection. • Regulatory requirement for inspecting turnouts, track crossings and lift rail assemblies or other transition devices on moveable bridges to be performed “on foot”

    7. Train Inspection • Provides a “feel” of the track under loaded conditions • Frequency depends on amount and type of train traffic, anywhere from twice annually to monthly • No regulatory requirement – Company Policy

    8. Types of Track Inspection • Normal or Scheduled (Routine) • Regulatory Compliance • Company Standard • Special Inspection • Specific Planned (i.e. Culverts, Rail Wear etc) • Emergency (Weather related, Incidents/Accidents) • Specialized Inspection Vehicles • Rail Flaw Detection Vehicles • Track Geometry Vehicle

    9. Scheduled Inspections • Regulated, Mandatory inspection of Main track and sidings (Hi-rail or Walking) • Monthly Inspection of “Other than Main” track, Turnouts & Special Track Work (Walking) • FRA/Transport Canada outlines minimum inspection frequencies • Report of tracks inspected, conditions found and actions taken are completed during the inspection.

    10. Track Safety Standards 46 CFR 213 SUBPARTS A-F • GENERAL • ROADBED • TRACK GEOMETRY • TRACK STRUCTURE • TRACK APPLIANCES & DEVICES • INSPECTIONS

    11. Defects • Defect Classification • Class of Track (Speed) Specific • Quantitative • Non-Class of Track Specific • Quantitative • Qualitative • Defect Identification • Visual • Hidden Repair Restrict Remove
