CSX’s Total FRA Reportable Broken Rail Main and Siding Derailments

This includes T201, T202, T203, T204, T207, T208, T210, T211, T212, T219, T220, T221

Railroad performance

• Long Term Trend

– Reduced broken rail derailments

Risk Evalua9on FRA 213

• FRA regula9on and CSX evaluates segments of track based
• n Service Failures per mile per year.
• FRA regula9ons were published in 2014.

– .10 RSF per year per mile of track for class 4, or class 5 – .09 RSF per year per mile of track with passenger or Hazmat for class 3, class 4, and class 5. – .08 RSF per year per mile of track with Hazmat and passenger for class 3, class 4, and class 5.

Correc9ve Ac9ons

• Adjust Rail Test Frequency
• Rail Grinding
• Capital Planning – Rail Replacement
• Lubrica9on / Fric9on Modifiers
• Temporary Slow Order and Remedia9on
• Develop and explore new technologies and advancements in

Service Failure Preven9on

Rail Defect Data Risk Assignment Test Frequencies Rail Test Scheduling Rail Tes9ng

Rail Test Integra9on and Modeling

Inputs into the model,

• Detected Defect Data
• Service Failure Defect Data
• Previous Frequencies
• Track informa\on – SGL, 1, 2,..
• HazMat Routes
• Tonnage
• Passenger Routes
• Speed
• Signal informa9on

Rail Replacement

– Extending and maximizing life is accomplished by many factors and not just one. CSX uses a holis9c approach. – Taking all the inputs and pu\ng your resources where you need it based on many factors.

• Defect history
• Age of rail
• Wear and predic9ve wear
• Risk assignment
• Curvature and Grade

Rail Grinding

• Maintenance or Correc9ve Grinds
• Rail is the most expensive component of the track
• Grinding has evolved to help control wear on rail and wheel by managing

WR Contact.

• Frequencies are based on many variables

– Including type of track – Tonnage – curvature – Profile

8

Lubrica9on/ Fric9on Modifiers

– Gage Face

• Lubrica9on in curves has proven to be an effec9ve technique to

reduce rail and wheel wear

• Extends wear life
• Reduces curving forces
• Reduces Wheel Flanging noises

9

Lubrica9on/ Fric9on Modifiers

– Top Of Rail Fric9on Modifiers

• CSX has been using TOR now for over 5 years
• Wheel tread to distribute the fric9on modifier
• Reduces wheel flanging noise and wheel squeal
• Posi9ve fric9on during wheel slippage
• Reduces L/V Forces which reduces rail rollover and gage widening
• Reduces Rail corruga9on

What is new and coming to help manage rail integrity

• Eddy Current
• Phased Array
• Run on Run Real Time Analysis of Test Data
• Con9nuous Non- Stop Ultrasonic Tes9ng
• Advancements in Machine Vision for RCF
• Thermal Imaging
• Laser based ultrasonic
• Big Data Integra9on
• Base Rail Tes9ng
• …..

*** All will be a piece of the puzzle for lowering risk
