RA620017 Hazardous Material Release From Railroad Tank Car With Subsequent Fire at Riverview, Michigan, July 14, 2001

Cause: A  fractured cargo transfer pipe that resulted from (1) the failure of ATOFINA to adequately inspect and maintain its cargo transfer equipment, and (2) inadequate Federal oversight of unloading operations involving hazardous materials. Contributing to the accident were ATOFINA’s reliance on a tank car excess flow valve to close in the event of a leak from cargo transfer equipment and the company’s failure to require appropriate safety equipment for employees involved in tank car loading and unloading operations.

RA620018 Hazardous Material Release From Railroad Tank Car With Subsequent Fire at Riverview, Michigan, July 14, 2001 (Brief) USA 2002 5 FREE
RA620010 Derailment of CSX Freight Train Q316 and Subsequent Hazardous Material Release at Cox Landing, West Virginia on June 20, 1998
Cause:  Unstable roadbed that resulted from inadequate or ineffective measures taken to permanantly correct known drainage problems.
USA 1999 38 $28.50
RA620001 Failure of Tank Car TEAX 3417 and Subsequent Release of Liquified Petroleum Gas in Pasadena, Texas on November 22, 1997
Cause : Thermal shock failure and subsequent leakage caused when contractor failed to ensure that nitrogen was properly warmed before being injected into the tank car during nitrogen purging.
USA 1997 29 $25.50
RA620015 Rupture of a Railroad Tank Car Containing Hazardous Waste Near Clymers, Indiana on February 18, 1999
Cause:  Failure of management to develop and implement safe procedures for offloading toluene diisocyanate matter wastes, resulting in the overpressurization of the tank car from chemical self-reaction and expansion of the toluene diisocyanate matter wastes.
USA 1999 79 $34.00
RA620002 Tank Car Failure and Release of Corrosive and Poisonous Liquid Involving Tank Car ACAX 80010 in the Illinois Central Railroad Yard in Memphis, Tennessee on April 2, 1997
Cause : Inadequate heat treatment to reduce the hardness of the weld material used in the repair of the tank to a level that would retard or prevent hydrogen-assisted cracking and inadequate testing to determine whether the weld material hardness exceeded established limits.
USA 1997 6 $10.00
RA620003 Tank Car Structural Failure and Release and Ignition of Propane Involving Tank Car UTLX 803627 in Conrail's Selkirk Yard, Selkirk, New York on March 6, 1996
Cause : Defective weld overlay repair adjacent to the manway that resulted in an overstress fracture near the manway. Contributing to the accident was the brittleness of the tank steel, which promoted the rapid propagation of the overstress failure. The tank completely separated into two halves and one of the halves was propelled, along with the four freight cars coupled to it, almost one mile down the track by the force of the explosion.
USA 1996 4 $10.00
RA620004 Tank Car Failure and Release of Flammable and Toxic Liquid Involving Tank Car GATX 92414 near Sweetwater, Tennessee on February 7, 1996
Cause : Installation of discontinuous bottom reinforcement bars, which concentrated stresses on pre-existing welding-induced cracks in the middle of the tank, causing tank car to shear almost completely in half during train move. Contributing to the accident was the brittleness of the tank steel which promoted rapid propagation of the overstress fracture.
USA 1996 6 $10.00
RA620005 Tank Car Failure and Release of Poisonous and Corrosive Vapors Involving Tank Car UTLX 92329 at the Gaylord Chemical Corporation Plant in Bogalusa, Louisiana on October 23, 1995
Cause : Lack of adequate procedures on the part of Gaylord Chemical Corp. and Vicksburg Chemical Co. to prevent or detect the contamination of nitrogen tetroxide with water, resulting in the formation of an extremely corrosive product and the subsequent failure of the tank car. Contributing to the severity of the accident were the Gaylord Chemical Corp.'s inadequate procedures for emergency transfer of contaminated cargo from the tank car.
USA 1995 4 $10.00
RA620009 Tank Car Failure and Release of Arsenic Acid in Chattanooga, Tennessee on June 6, 1994
Cause:  Tank car owner failed to detect and correct misalignment of eduction pipe system, which mechanically damaged the protective coating of the tank at the sump, leading to the corrosion and failure of the tank.  Contributing to the severity was a lack of means to contain spill within yard, delay in notifying spill cleanup contractor.
USA 1995 75 $34.00
RA620011 Derailment of Burlington Northern Freight Train No. 01-142-30 and Release of Hazardous Materials in the Town of Superior, Wisconsin on June 30, 1992
Cause:  Failure of the rail from an undetected preexisting detail fracture that had initiated from shelling and had reached critical size.  Also causal were (a) the Federal Railroad Administration track safety standards, which failed to adequately address rail-head surface conditions (such as shelling) that are known to be associated with rail fracture modes and failed to require remedial action; and (b) the lack of objective criteria to assess the risk posed by shelled rail, which has not been adequately addressed by the railroad industry and the Federal Railroad Administration.

RA610002 Inspection and Testing of Railroad Tank Cars - Special Investigation Report USA 1992 44 $28.50
RA620013 Derailment of a CSX Transportation Freight Train and Fire Involving Butane in Akron, Ohio on February 26, 1989
Cause:  Inadequate rebuild and quality control procedures and inadequate inspections by car inspectors that permitted the car to enter and continue in service with excessive gib clearance and out-of-limits side bearing clearance.  Contributing factor was marginal condition of track due to delay in rehabilitation of track and absence of slow order.
USA 1990 104 $36.50
RA620012 Butadiene Release and Fire From GATX 55996 at the CSX Terminal Junction Interchange, New Orleans, Louisiana on September 8, 1987
Cause:  Misalignment and subsequent tearing of the bottom manway gasket when the manway cover was improperly closed.  Contributing to the improper closing of the manway cover were the lack of established procedures by both the North American Tank Car Corp. and Phillips 66 for correctly using the uniquely designed cover hinge and the insufficient training of the carman who performed the work.  Contributing to the length of the emergency and the increased risk to life and property were the lack of any means to stop the flow of butadiene from the bottom manway of the tank car and the failure of responding personnel to comprehend the extent of the danger posed by the burning tank car and to promptly evacuate the area threatened.
USA 1988 81 $34.00
RA620014 Hazardous Materials Release Following the Derailment of Baltimore and Ohio RR Co. Train No. SLFR, Miamisburg, Ohio on July 8, 1986
Cause:  Failure of the unprotected bottom brake support attachment during the derailment resulting in the tearing of the tank shell.  Contributing to the rupture of the tank was the Federal Railroad Administration's failure to require retroactively that reinforcement pads be installed between tank shells and welded attachments.
USA 1986 95 $34.00
RA620008 Anhydrous Hydrogen Flouride Release from NATX 9408, Train No. BNEL3Y at Conrail's Receiving Yard in Elkhart, Indiana - February 4, 1985
Cause: Railroad continued transporting car known to be leaking.  Leak resulted from failure of the tankcar head at a weld undercut made during its construction.  Contributing to the extent of the emergency was the failure of mechanical and supervisory personnel to take prompt, appropriate action once notified of the leak.
USA 1985 43 $28.50
RA620006 Hazardous Materials Release - Missouri Pacific Railroad Company's North Little Rock, Arkansas Railroad Yard - December 31, 1984
Cause: Ethylene oxide leaked from tank car through two through-shell cracks near the center of the bottom of the tank at each extremity of the welds on the anti-shift bracket.  Tank car jacket was improperly welded.  In addition, railroad personnel were poorly trained in emergency response, railroad had no emergency response plan for the yard.
USA 1984 28 $28.50
RA620007 Release of Oleum During Wreckage-Clearing Following Derailment of Seaboard System Railroad Train Extra 8294 North - Clay, Kentucky - February 5, 1984
