This 1970s color film produced by the Herb Golden Organization for Dynamic Sciences.
This sponsored film was filmed in cooperation with the Federal Railroad Administration’s Office of Rail Safety Research, with Frank Capra, Jr. credited as Executive Producer. The film looks at safety problems related to railroad gas petroleum tank cars, and shows innovative developments that will make them safer by using thermal insulation techniques. Findings of the U.S. Ballistic Research Laboratory were used to develop these concepts, with the hope being that the disastrous effects of collision and derailment-related chain explosions could be mitigated. The research uses slow motion techniques to document the investigation and its related experiments (TRT 21:33).
Opening titles, “U.S. Army ARRADCOM” -- U.S. Army Armament Research and Development Center -- and “Ballistic Research Laboratory” (BRL) (0:07). A diesel locomotive freight train pulling tank cars (0:17). A train derailment and wreck. A punctured, derailed tank car emitting flames. Then, an enormous explosion. Wreckage and debris (0:42). Large tanks of gas are transported across a wide-open plain via truck, for a government test. The test tank is shown in an excavated pit. Passing freight cars in a train yard, on railroad tracks (0:59). Exterior: Ballistic Research Laboratory. Flaming scenes of accidental explosions (1:42). An Exxon gas filling station. Warning signs: “Flammable Gas, Liquefied Petroleum Gas” and “Dangerous, Propane, Handle Carefully.” Exploded pipeline (2:14). Firefighters in red uniforms and hardhats. A destroyed brick building. A gas explosion (2:46). A freight car collides with a tank car, triggering a controlled explosion in slow motion test footage (3:08). A dented tank car. A firefighter sprays water from an elevated fire truck ladder. A tank car section in a residential area. More ground blasts and fireballs (3:30). Smouldering wreckage and mushroom clouds. Aerial photography. Firemen arrive late to the smoky scene of a chaotic accident. A man, blackened by soot, removes his jacket (4:25). Research and development of small prototype tanks in White Sands, New Mexico. A man illustrates a physics equation on a chalkboard at the Transportation Systems Center in Cambridge, Massachusetts. Toy model trains reenact a collision. Testing a flame-retardant metal under high heat (5:17). An excavated site at White Sands Missile Range. A crane lifts a 1:5 scale tank into position onto a pipeline (5:50). A full-size test tank arrives at White Sands. A fire ignites and gas is burned off without exploding the tank (6:21). An animated illustration of the test depicts a flaming tank car emitting gas (7:52). “After 24 1/2 minutes,” an explosion (8:41). A blast crater (9:07). A second test car is sanded and painted with weather-resistant coating for insulation. Title cards over a burn indicate additional time bought by the added insulation. Stills reveal tanks left intact (9:43). A locomotive crosses an elevated coastal bridge (11:36). Chalkboard illustrations show a radiating blast resulting from a tank puncture (11:55). A torch simulator is constructed and demonstrated at the Transportation Test Center (TTCI) in Pueblo, Colorado (12:15). Thermal coated sections of metal are shown before and after extended blowtorching. A real tank car is torched. Superimposed titles boast extended reaction times (13:38). A woman types at an early computer in Cambridge, Massachusetts. Magnetic tape memory drives. Aerial footage of the TTCI. A wide shot of a test collision in slow motion. Closeups of train car coupling (14:26). A grid is superimposed for analysis. A trapezoidal shield and a double-shelf coupler are installed (16:29). The shield prevents a puncture. The new coupler prevents separation (18:20). A successful test crash and review of previous scenes (19:30). An oncoming train approaches a railroad crossing. End titles (20:40).

The tests at approximately 16.00 minutes were done as the result of a massive yard fire in Decatur, IL in 1974. In this fire, a propane car was punctured by a humped car's knuckle coupler. A number of changes to tank car design were made as a result of this event.
Actually, Decatur was and is a flat yard. Instead of humping, they used to, and probably still do, "flying switches". A car is accelerated to 10-15 mph by a switch engine then the car is uncoupled and allowed to roll unattended to the next car. In the '74 incident, the speed was excessive and an empty car hit a full propane car as in the test film. The empty rode up and over the full car's coupler allowing its couple to puncture the old style unarmored dished end. BOOM!
Excellent video. Those LPG rail-cars can be rolling urban renewal devices.
Behold. The discovery of the boiling liquid expanding vapor explosion
Another interesting and great video from Periscope.
Glad you found it!
Before the term BLEVE
This was the advent of the change from DOT-111 tank cars to the insulated DOT-117. The implementation was to be completed by 2025. So it took 50 years and many accidents before the regulation went into effect in 2015. Some railroads saw the writing on the wall and started ordering new 117 cars before the regulation. I inspected and photographed an ethanol derailment in Fort Worth a few years ago. None of the 117 cars exploded however the three111 cars were ruptured and leaked ethanol into a stream which caught fire. FYI: alcohol fires are almost invisible. Weather was the cause of the derailment. No serious injuries.
OMG, at time 5:08 the poor guys clothing is still smoking. I pray he survived without severe injuries.
After the video , I'll need a 500 word essay on my desk tomorrow. If you dont write it , you'll be in , in school suspension for a week. I'm almost 45 , n I still miss them days
when you were young and basically know very little about the world, 500 words essay was quite a task
At that time , my imagination was wild n still love to write , its weird, but it's cool.
@@christopherstrong4119 cool
Every time I hear this guy narrating, I want to play the video about the Turbo Encabulator.
Modial interface...
Great!!!
5:06 You can hear the "Hey! Give me a hand with.." background chatter that was commonly used on "Emergency!"
If not already covered, a video similar to this on tank cars carrying dangerous, chemicals, acids etc. Another great video on everything. Where does Perscope track all this down?

I wonder if the changes have actually been implemented? After all, the cost of updating thousands of tank cars and having them out of action for weeks or months would hit the shareholders profits. Unless there were laws forcing the rail companies to comply with the changes I expect that only new tank cars would be built with them.
Interesting question. You'd be surprised what I just learned -- according to Wikipedia, up to 80% of the Canadian fleet and 69% of U.S. rail tank cars were DOT-111 type, as of 2013.
it was done over time when overhauls and rebuilds were done on most that weren't replaced from what i've been told by railroaders in the family!!
@@PeriscopeFilm taking wiki as fact on anything is dubious at best!! you don't have anything on how fire direction centers for artillery and artillery fuses work by chance? i can't find anything showing any ofnthat stuff anywhere on the tube!
if proven effective the upgrade would definitely reduce the accident lost. the companies can do the math
🏃 It's gonna blow! 🏃
As endless trains of crude oil run through our town, one wonders if the safety of that idea has been considered by an industry that seems stuck in the 20th century.
well it seems Canada has a missing town that'll answer that for you!!! wouldn't need tanker drags if certain senile asswipes in DC wouldn't kill off pipelines as soon as being sworn in!!!
3:09 / it took teams of investigators and millions of dollars to determine that of a tank car was breached it could start a fire
How tje government spends your money
With current events I call bullshit
