Safety Recommendation R-69-006
Details
Synopsis: ABOUT 9:30 P.M., JANUARY 1, 1968, PENNSYLVANIA WESTBOUND FREIGHT TRAIN PR-11A, CONSISTING OF 98 CARS AND A FIVE-UNIT DIESEL-ELECTRIC LOCOMOTIVE, WAS PASSING DUNREITH, INDIANA, AT 42 MILES PER HOUR WHEN THE TRAILING WHEELS OF THE 88TH CAR, AN EMPTY TANK CAR, AESX 850, DERAILED AT A BROKEN RAIL NEAR THE EASTERN EDGE OF THE TOWN. AT THE SAME TIME, EASTBOUND FREIGHT TRAIN SW-6, CONSISTING OF A FIVE-UNIT DIESEL-ELECTRIC LOCOMOTIVE AND 106 CARS, WAS MOVING EASTWARD AT 32 MILES PER HOUR ON THE ADJACENT TRACK.
Recommendation: THE NTSB RECOMMENDS THAT THE AMERICAN RAILWAY ENGINEERING ASSOCIATION AND THE ASSOCIATION OF AMERICAN RAILROADS: INITIATE A RESEARCH PROGRAM TO IMPROVE THE PRESENT RAIL-JOINT DESIGN. THE IMPROVED JOINT SHOULD BE AS STRONG AND DEPENDABLE AS THE RAILS TO WHICH APPLIED AND ALSO PREVENT THE DEVELOPMENT OF RAIL DEFECTS AND FAILURES WHICH NOW COMMONLY OCCUR IN THE JOINT AREA.

Response: 1/16/73 - ASSOCIATION OF AMERICAN RAILROADS LTR: AAR TRANSMITTED RAILROAD SAFETY RESEARCH STATUS REPORT. THE AAR HAS STUDIED THE RAIL JOINT DESIGN PROBLEM OVER A PERIOD OF MANY YEARS AND IS CONTINUING IN THE DEVELOPMENT AND TESTING OF NEW TYPES OF DESIGNS OF JOINT BARS AND THEIR METHOD OF APPLICATION. THIS IS BEING DONE IN A COOPERATIVE EFFORT WITH THE RAILROADS AND THE MANUFACTURERS. A GENERAL STUDY IS IN PROGRESS ON IMPROVED RAIL MATERIALS WHICH, IF DEVELOPED, COULD FURTHER REDUCE THE FREQUENCY OF RAIL JOINT AREA FAILURES. FURTHER STUDY IS CONTEMPLATED IF FUNDING IS MADE AVAILABLE FROM THE FRA ON THE BROAD ISSUE OF TRACK STRUCTURE, INCLUDING PERFORMANCE OF THE RAIL JOINT.
