APPENDIX: TANK-CAR ACCIDENT DOCUMENTATION FORMS 128
.
Background

On April 8, 1979, 28 cars of a southbound freight train derailed 3.8 miles north

of Crestview, Florida. The train [1] had departed Pensacola, Florida at 5:25

a.m. as No. 403, a second class freight train, consisting of five

diesel-electric locomotive units, 107 loads, six empties, and a caboose, with a

total weight of 11,360 tons. Shortly after 8:00 a.m. the 41st through the 68th

car derailed (car number referenced from the first or lead locomotive). The

69th car came to rest at a bridge structure that became weakened from a fire and

this lead to the subsequent derailment of that car. Of the 29 cars that

derailed, 28 were tank cars. Twenty six of the derailed tank cars contained

hazardous materials; seventeen contained anhydrous ammonia, three contained

acetone, four contained methanol, one contained chlorine and one contained

carbolic acid. Two of the anhydrous ammonia cars ruptured and rocketed. The

£ contents of the three cars of acetone and one car of methanol completely burned.

One of the other methanol cars broke in half, and the contents completely

burned. Six cars of anhydrous ammonia, one of chlorine, and one of carbolic

acid developed leaks from various causes. A large cloud of vapor and smoke

developed, blanketing the immediate area, eventually spreading over an area

three to five miles wide. A schematic is shown in Figure 1 showing the

locations of the derailed cars at the accident site as reported by the railroad.

[1] Railroad Accident Report, Louisville and Nashville Railroad, Crestview,

Florida, April 8, 1979; U.S. Department of Transportation , Federal Railroad

Administration, Office of Safety, May 1979.

1
In response to a request by the Federal Railroad Administration (FRA), personel

of the National Bureau of Standards (NBS) and of the FRA visited the site of

this accident. The purpose of this visit was twofold. First, to make

observations that could be useful in studies of the properties and behavior of

railroad tank cars subject to abusive service conditions, such as those that

occur in accidents of the types described above. Second, to select samples from

damaged tank cars for use in later investigations at the NBS laboratory.

Observations

This report contains observations made on two separate visits to the vicinity of

the accident site. The first of these two visits was made on April 19, 1979 by

NBS investigators Dr. C.G. Interrante and Dr. J.G. Early and a representative

from the FRA, Mr. D. Dancer. During this visit, extensive notes were taken of

the conditions of the various cars that had been derailed and this was done at

or nearby the site of the derailment. In addition, extensive photographs were

taken to document the conditions of each of the derailed tank cars. Other

observations included those of the path and orientation of fracture along with

the mode of fracture for selected steel plates that were accessible. At that

time, a total of twenty one plate samples were marked with NBS identifications.

Some plates had two samples marked on them, such as samples 20A and 20B, for

use in later investigations of the steels used in selected tank cars that had

been damaged in service. For the derailed tank cars, Table 1 summarizes the

information on tank car number, location within the train, DOT tank car class,

NBS sample number, and the number of photographs taken.

2
During that first visit, each derailed tank car was observed and photographed,

and special attention was given to all cars that had been severely damaged,

either with large dents or fractures. Most of the cars had been repositioned

from any original (derailed) sites at which they came to rest following the

accident. Sketches were made of fractures that severed cars into two or more

pieces and fracture path (direction) notations were made. Notes were also taken

on all observations of dents and cracks or through thickness ruptures for all

accessible parts of the cars. Parts of some cars were inaccessible because the

air was still heavily laden with anhydrous ammonia fumes. Thus, close

observation was made impossible for some fractured tank cars and work was

halted.

The second visit was made by Dr. J.G. Early and Mr. S.R. Low of the NBS on May

8-9, 1979. By that date, the derailed cars had been loaded onto railroad flat

£ cars and gondola cars and transported to a railroad siding. Sketches and other

information taken during the first visit had been transferred onto worksheets

that were designed specifically for selected types of information, as described

later. These worksheets were completed during the second field visit. New

data included measurements of plate thickness at various distances from selected

fracture surfaces to determine the degree of plate thinning, as well as

additional observations of fracture mode and appearance. The latter were made

because some surfaces that were not exposed to view on the first visit were

exposed after the cars had been moved.

3
Documentation

The information taken on tank cars is presented on special forms designed for

this purpose. The principal form is titled "Inspection Report of a Tank Car

Involved in an Accident". It gives the basic information on a tank car, such as DOT Class, commodity and mechanical information, as well as lists of any

photographs taken of the car and a description of observations. This form is

supplemented by photographs (where appropriate). Several other forms titled

TANK-CAR ACCIDENT DOCUMENTATION, with various sub-titles: DAMAGE AND SAMPLES,

FRACTURE PATH, FRACTURE MODE, and PLATE THINNING may be used to complete the

documentation. These are forms used for 1) sketching the location and extent of

damage or the location of samples, 2) sketching fracture paths, 3) sketching

fracture modes, and 4) recording the extent of plate thinning near selected

fractures. A sample of each of these types of data forms are given as an Appendix to this report. 4 The forms contain information needed to minimize the

ambiguity in interpretation of the data and observations presented on them and

thus, are valuable aids for the subsequent metallurgical evaluation of the

behavior of the materials of construction.

Summary

This report contains the results of the field investigation of the behavior and

response of 28 tank cars which derailed on April 8, 1979 near Crestview,

Florida. The pictorial representation of the damage to the cars as well as the

field measurements and other data necessary for subsequent metallurgical

evaluation of the materials of construction are reported on a series of prepared

forms developed for field accident investigation.
