How Does Technology Affect Railcar Maintenance

Advanced Technology Safety Initiative (ATSI)Ken Henman

DTE Rail Services, Inc. Maintenance Management Seminar


Advanced technology safety initiative atsi overview
Advanced Technology Safety Initiative – ATSIOverview

  • AAR initiative to make the overall freight interchange system safer and more efficient

  • Utilize new technology that facilitates more sophisticated assessment of the condition of in-service equipment

  • Provides immediate, reliable indicators of vehicle performance in a dynamic operating environment

DTE Rail Services, Inc. Maintenance Management Seminar


Advanced technology safety initiative atsi overview1
Advanced Technology Safety Initiative – ATSIOverview

  • Creates opportunities for proactive predictive maintenance intervention

  • Reduces reliance on manual inspection that only identifies component failure or excessive worn conditions

  • Results are enhanced performance and safety with a net reduction in overall system costs

DTE Rail Services, Inc. Maintenance Management Seminar


Atsi background
ATSI- Background

  • In the past Class I railroads have been able to optimize maintenance spending between rail infrastructure and railcars

  • The railroads concern for equity interests and financial liabilities had to be balanced against railroad operating efficiencies and/or capital improvements

DTE Rail Services, Inc. Maintenance Management Seminar


Atsi background1
ATSI- Background

  • Over time, the percentage of the U.S. freight car fleet owned by Class I railroads has declined

35.3%

55.7%

9%

Atsi background2
ATSI - Background

  • Class I railroads now have less direct control over maintenance spending on railcars

  • Class I railroads are concerned about safety and damage to track structure

  • Poorly performing cars introduce unnecessary high cost

    • Reactive based maintenance is to risky and costly

    • Direct effect resulting in high car maintenance costs

    • Direct effect on track infrastructure maintenance costs

    • Indirect effect on system capacity and car availability

DTE Rail Services, Inc. Maintenance Management Seminar


Atsi background3
ATSI - Background

  • Class I railroads don’t want to maintain other people’s railcars

  • Costs to perform manual inspections for failed components is prohibitively expensive

    • *2005 Interchange repair and maintenance cost $332 Million

    • *Interchange inspection costs $270 Million

Atsi background4
ATSI - Background

  • Class I railroads/AAR saw need to reduce direct costs through:

    • Reduced physical inspection

    • Planned maintenance (predictive data driven scheduling, not time based)

    • Focused maintenance (efficient repair of only what is necessary)

    • Reduced out of service time with predetermined maintenance planning

    • Data accumulation and sharing lends to root cause analysis

DTE Rail Services, Inc. Maintenance Management Seminar


Atsi summary1
ATSI- Summary (FACTIS)

  • Data supplied by AAR so car owners can better manage maintenance on their cars

    • Identifies problem railcars across the Interchange system

    • Data serves as a means for root cause analysis

    • Allows opportunities for car owners to proactively manage maintenance on their cars

  • AAR revising rules improving maintenance standards for cars

DTE Rail Services, Inc. Maintenance Management Seminar


Atsi phase i
ATSI- Phase I (FACTIS)

  • Wheel Impact Load Detectors (WILD) implemented October 1, 2004

    • Measures impact load of wheels upon track structure

    • KIPs is a unit of weight equal to 1000 lbs

    • Identifies out-of-round wheels

    • Four levels of alerts

      • Window Opening 65-80 KIPs

      • Window of Opportunity 80-90 KIPs, why made 61

      • AAR condemning 90-140 KIPs, why made 65

      • Final alert 140+ KIPs

    • Car owners receive notification prompting the opportunity to intervene and schedule the wheel for replacement
