Mechanical Failure”

2. Joint Wayside Diagnostic System - JWDS
Goal – Proactive identification of mechanical risks to minimize line of road stops
Eliminate mechanical-caused line of road stops and derailments
Reduce the stress state of our Railroad
Centralized repository for ALL detector data
Identifies and prioritizes conditions we want to know
Enables car inspectors to move from finders to fixers
CSX, UP and NS share software and rules logic through the JWDS Consortium.

3. Joint Wayside Diagnostic System - JWDS
Before JWDS, we were
REACTIVE
to what the detector was telling us.
Now… we are
PROACTIVE
as to what the equipment is telling us.

4. Web of Detector Acronyms
ABD – Acoustic Bearing
Listens to passing trains for bearing & locomotive gear defects – early warning
AEI - Automated Equipment Identification
Radio Frequency based system that reads car and locomotive tags
Allows us to piece the defect information to the car and position on the car in JWDS
HBD/WTD – Hot Bearing – Wheel Temperature
HBD measures the temperature of roller bearings and reports defects as an axle count from head end of train
WTD measures heat on wheels to see cars in trains that are in braking and should not be or cars not braking that should – Effective Braking & overheating wheels
OGD – Optical Geometry - Truck Performance
Laser/Vision system to measure the relationship between the wheel flange and the rail gauge
WILD – Wheel Impact Load, Hunting Truck & Overload-Imbalanced Load
Measure wheel impacts in both horizontal and vertical directions to determine the degree of wheel impacts and loading conditions of cars
WPD – Wheel Profile
Laser/Vision System to measure wheel profiles thresholding for AAR/FRA defects such as: High Flange, Thin Rim or Thin Flange, Hollow Worn etc.

25. WILD Wheels
This wheel was measured with 153,000 pounds of force banging on the rail with every rotation.
This wheel shows initial flat spots developing.
