Let's talk refinery explosions before we give 'big oil' a break on safety -
Energy industry[edit] See also: List of pipeline accidents in the United States in the 21st century and List of natural gas and oil production accidents in the United States October 1957: The Windscale fire, the worst nuclear accident in Great Britain's history, released substantial amounts of radioactive contamination into the surrounding area at Windscale, Cumberland (now Sellafield, Cumbria). May 1962: The Centralia, Pennsylvania coal mine fire began, forcing the gradual evacuation of the Centralia borough. The fire continues to burn in the abandoned borough. March 1967: The Torrey Canyon supertanker was shipwrecked off the west coast of Cornwall, England, causing an environmental disaster. This was the first major oil spill at sea. August, 1975: The Banqiao Dam failed in the Henan Province of China due to extraordinarily heavy rains and poor construction quality of the dam, which was built during the Great Leap Forward. The flood immediately killed over 100,000 people, and another 150,000 died of subsequent epidemic diseases and famine, bringing the total death toll to around 250,000 and making it the worst technical disaster ever. March 16, 1978: The Amoco Cadiz, an VLCC owned by the company Amoco (now merged with BP) sank near the northwest coast of France, resulting in the spilling of 68,684,000 US gallons of crude oil (1,635,000 barrels). This is the largest oil spill from an oil tanker in history. March 28, 1979: Three Mile Island accident. Partial nuclear meltdown. Mechanical failures in the non-nuclear secondary system, followed by a stuck-open pilot-operated relief valve in the primary system, allowed large amounts of reactor coolant to escape. Plant operators initially failed to recognize the loss of coolant, resulting in a partial meltdown. The reactor was brought under control but not before up to 481 PBq (13 million curies) of radioactive gases were released into the atmosphere.[1] June 3, 1979: Ixtoc I oil spill. The Ixtoc I exploratory oil well suffered a blowout resulting in the third-largest oil spill and the second-largest accidental spill in history. November 20, 1980: A Texaco oil rig drilled into a salt mine transforming Lake Peigneur, a freshwater lake before the accident, into a saltwater lake. February 15, 1982: Newfoundland, Canada. The mobile offshore oil rig Ocean Ranger was struck by a rogue wave off the coast of Newfoundland, Canada and sank with the loss of all 84 crew. July 23, 1984: Romeoville, Illinois, Union Oil refinery explosion killed 19 people. November 19, 1984: San Juanico Disaster. An explosion at a liquid petroleum gas tank farm killed hundreds and injured thousands in San Juanico, Mexico. April 26, 1986: Chernobyl disaster. At the Chernobyl nuclear power plant in Prypiat, Ukraine a test on reactor number four went out of control, resulting in a nuclear meltdown. The ensuing steam explosion and fire killed up to 50 people with estimates that there may be between 4,000 and several hundred thousand additional cancer deaths over time. Fallout could be detected as far away as Canada. The Chernobyl Exclusion Zone, covering portions of Belarus and Ukraine surrounding Prypiat, remains contaminated and mostly uninhabited. Prypiat itself was totally evacuated and remains as a ghost town. May 5, 1988: Norco, Louisiana, Shell Oil refinery explosion. Hydrocarbon gas escaped from a corroded pipe in a catalytic cracker and was ignited. Louisiana state police evacuated 2,800 residents from nearby neighborhoods. Seven workers were killed and 42 injured. The total cost arising from the Norco blast is estimated at US$706 million. July 6, 1988: Piper Alpha disaster. An explosion and resulting fire on a North Sea oil production platform killed 167 men. The total insured loss was about US$3.4 billion. To date it is rated as the world's worst offshore oil disaster in terms both of lives lost and impact to industry. March 24, 1989: Exxon Valdez oil spill. The Exxon Valdez, an oil tanker bound for Long Beach, California, hit Prince William Sound's Bligh Reef, dumping an estimated minimum 10.8 million US gallons (40.9 million litres, or 250,000 barrels) of crude oil into the sea. It is considered to be one of the most devastating human-caused environmental disasters ever to occur.[2] 100,000 to as many as 250,000 seabirds died, as well as at least 2,800 sea otters, approximately 12 river otters, 300 harbor seals, 247 bald eagles, and 22 orcas, and billions of salmon and herring eggs were destroyed.[3] Overall reductions in population have been seen in various ocean animals, including stunted growth in pink salmon populations.[4] Sea otters and ducks also showed higher death rates in following years, partially because they ingested prey from contaminated soil and also from ingestion of oil residues on their hair/feathers due to grooming.[5] The effects of the spill continue to be felt 20 years later. March 23, 2005: Texas City Refinery explosion. An explosion occurred at a BP refinery in Texas City, Texas. It is the third largest refinery in the United States and one of the largest in the world, processing 433,000 barrels of crude oil per day and accounting for three percent of that nation's gasoline supply. Over 100 were injured, and 15 were confirmed dead, including employees of Jacobs, Fluor and BP. BP has since accepted that its employees contributed to the accident. Several level indicators failed, leading to overfilling of a knockout drum, and light hydrocarbons concentrated at ground level throughout the area. A nearby running diesel truck set off the explosion. December 11, 2005: Hertfordshire Oil Storage Terminal fire. A series of explosions at the Buncefield oil storage depot, described as the largest peacetime explosion in Europe, devastated the terminal and many surrounding properties. There were no fatalities. Total damages have been forecast as £750 million. August 17, 2009: Sayano–Shushenskaya power station accident. Seventy-five people were killed at a hydroelectric power station when a turbine failed. The failed turbine had been vibrating for a considerable time. Emergency doors to stop the incoming water took a long time to close, while a self-closing lock would have stopped the water in minutes. February 7, 2010: 2010 Connecticut power plant explosion. A large explosion occurred at a Kleen Energy Systems 620-megawatt, Siemens combined cycle gas- and oil- fired power plant in Middletown, Connecticut, United States. Preliminary reports attributed the cause of the explosion to a test of the plant's energy systems.[6] The plant was still under construction and scheduled to start supplying energy in June 2010.[7] The number of injuries was eventually established to be 27. Five people died in the explosion.[9] April 20, 2010: Deepwater Horizon oil spill in the Gulf of Mexico. Eleven oil platform workers died in an explosion and fire that resulted in a massive oil spill in the Gulf of Mexico, considered the largest offshore spill in US history.[10] March 2011: Fukushima I nuclear accidents in Japan. Regarded as the largest nuclear disaster since the Chernobyl disaster, there were no direct deaths but a few of the plant's workers were severely injured or killed by the disaster conditions resulting from the earthquake. October 29, 2012: Hurricane Sandy caused a ConEdison power plant to explode, causing a blackout in most of midtown Manhattan. The blue light emitted from the arc made places as far as Brooklyn glow. No person was killed or injured. July 6, 2013: Lac-Mégantic, Quebec Canada. Lac-Mégantic derailment. Forty-seven people were killed when there was a derailment of an oil shipment train. The oil shipment caught fire and exploded, destroying more than thirty buildings. It was the fourth-deadliest rail accident in Canadian history.
and List of natural gas and oil production accidents in the United States
Of all those listed - only 1 involved rail transportation. Electrical generation is also included in the list. Of course we can all retreat to cold, dark caves and walk to our destinations. Today's life styles involve risk in creating and maintaining them.
Never too old to have a happy childhood!
The point I am making has nothing to do with defending Big Oil. My point is to disagree with the logic of the point being made by the Railway Age article. The industry started out by agreeing to make tank cars safe for transporting the volatile oil. Now Railway Age seems to be saying that the safe tank car objective cannot be met because there is more volatile oil than we thought.
This is and will continue to be a urination contest between rail interests and oil interests, both pointing their fingers at each other and it will remain so until someone breaks their fingers.
The problem is that both rail and oil SHARE the responsibility for making and transporting the product safely. Rail is attempting to improve the safety margins in the new cars (without ANY assurances that what they are doing is at least on the same line of thinking that the Regulations will ultimately require - whenever they are published). Oil's argument that their product safe until subjected to an accident, is that of a recalcitrant two year old that cannot understand nor accept responsibility for any of their actions. After all Big Oil still thinks ENRON was a well run business.
Euclid The problem of exploding oil trains cannot be fixed by an extra eighth-inch of steel. The lading is exploding, not the cars.”
That is merely "posturing". They are trying to manipulate $liability onto other quarters.
Here is the meat of it. The Railroads are the transportation experts. They are expected to possess mastery of the requirements necessary to safely transport items they have been contracted to do so.
If the railroads believe there are other measures necessary to make the lading safe for transport, then they are certainly entitled to demand same from their customer prior to accepting for shipment (or refuse the business).
None of these incidents that I am aware of involve lading that just spontaneously exploded. The transport people's "contribution" to the unexpected far outweighs any contribution at the wellhead.
Tank cars could be made strong enough to withstand an atomic bomb exploding ten feet above them. Problem is, they'd only hold one gallon of oil.
Norm
If only the tank cars could survive the wrecks and not spill oil. Then it wouldn't matter what the volatility was. Of course, it would be nice not to have the wrecks in the first place.
If only the product wasn't so volatile, then it wouldn't matter if a tank car failed in a wreck, as it wouldn't be as likely to burn/explode.
As has been mentioned, this appears to be an exercise in transferring blame/responsibility.
After all, I'm OK. It must be you that has the problem. Rhetorically speaking, of course.

Norm48327 Tank cars could be made strong enough to withstand an atomic bomb exploding ten feet above them. Problem is, they'd only hold one gallon of oil.
While making the tank car walls thicker will obviously strengthen them somewhat, I see 2 flaws to that logic, at least until the post-accident studies and reports can tell us a whole lot more about the mechanism and sequence of the failures:
- Paul North.
And let's not forget the possibility of two trains moving in opposite directions tangling due a derailment by one or the other.
The oil train may be limited to some lower speed, but even if the oncoming train is also limited to, say, 45 mph, the closing speed could be 90 mph, or higher. A baretable flat turned spear would probably defeat even the full headshield on a "new" tank car.

Read the paragraph below the 2nd picture. It says the new design tank car is designed for slow speed accidents and roll overs. That it or the awaiting for official approval designs also would not withstand high-speed derailments or collisions.

snipped from the link provided by jeffhergert:
FTL:"...The CPC-1232 car is designed to contain its lading in relatively slow-speed derailments and rollovers. As the Crowsnest Pass event indicates, they work as designed in low-energy incidents. Carbuilders themselves advise that neither the CPC-1232 nor its yet-to-be-approved official successor could withstand the forces of high-speed derailments or collisions.
The flow of crude by rail through Crowsnest Pass has increased markedly under an agreement between CP and Union Pacific to smooth the interchange of unit oil trains at the border between Idaho and British Columbia..."
This whole conversational topic of " Tank Car Safet,etc" would be a mute point. IF the subject had not become an International 'Political Football'; and thus allowing a reasonable approach to long distance transportation of the crude oil products, get lost in the weeds as political expedients took over. IMHO.
The railrioads, and the shipper's organizations have been trying new safety enhancements for years: double-shelf couplers; from several years back, the addition to the ends of the cars a heavy braced steel plate, to prevent punctures; also various appliance configurations of valves, and manholes. To name a few enhancements that have made it to real world operations.
I'm not sure where this is all going to end up. It seems that people want to live 'risk free'. An impossible task? Anytime, objects move about, there is risk of tasks going wrong. They may work thousands of times perfectly, but then the law of averages will kick in, and an incident will happen. How serious the incident is will depend on the factors present at that time. Some time back here on this Forum there was a discussion on highway-rail grade crossing incidents, and the injuries to tresspassers hit by moving equipment. I think, that someone had posed a link to research on placing air bags on the front of locomotives to help prevent injuries in those events (?). Point being, anytime we have advances with technologies, praticularly, in transportation, there is the potential for incidents with various levels of bad outcomes to the rest of society, as that technology is tried in a real environment. Trains will derail, trucks will wreck, automobiles will be involved, and people will be hurt. It is the risk we take to enjoy the level of convenience in a 'modern' society that most people seem to seek.
samfp1943It seems that people want to live 'risk free'.
I would opine that the 24 hour news cycle (and just plain always, everywhere coverage) have done more to make the world seem less safe than any increase in unsafe incidents. Where years ago an incident like Lynchburg might have garnered a couple of inches on page 9 of the paper, and maybe a few seconds on the local TV news within a certain radius, today it's splashed on multiple media, worldwide, live, and in living color.
As has been seen in other threads, grade crossing incidents are actually down. But what does occur gets major coverage, which might lead one to think that they are a greater problem instead.
I'll agree that political motives are a major part of the issue. These folks need to "make hay while the sun shines," exploiting any incident to its fullest in pursuit of their goals, which I would opine have little or nothing to do with rail safety.
I hate how the media only sees the negativity in trains. Railroad museums and other rail-related things have events that they run and can give the railroads a better image, but No the media only sees the bad in them. Be happy for once!
I kind of like what I percieve is the BNSF strategy evolving here. Ask the FRA for permission to deny carrying some hazardous cargos as a Common Carrier. Once permission is received setup your own specs for handling this cargo OR charge a premium for hauling it using the newly gained right of refusal.
Safe as possible, in the history of man has never equaled perfect safety.
"no tank car can be built to survive a high speed derailment without breaching"
It is an immutable law of physics that when two objects of like mass and weight collide the weaker of the two will be damaged.
Any idea if the required replacement of the tank car valves noted in today's newswire has any thing to do with explasions ?
The problem statement is pretty simple: The safety of hauing crude oil in tank cars needs to be improved.
The solution(s) are trickier and not yet clear. But, the gist of any solution will be two fold:
1. The improvements have to be weighed against the direct and economic impact costs. That is, it balances the improvement benefit against the total costs. This is not easy to calculate, but good faith estimates are possible. This will not include any language like "prevents", "always", "will", "won't" or "safe".
2. A politically palatable one from the view of the public. There is a political demand to "do something" and that something has to be perceived as "enough". This can have all sorts of absolute language in it.
If #1 and #2 have enough in common, we might actually wind up with a decent solution. So far, all we have is a bunch of flashy news video and some proposed regs still sitting with the FRA that are stalling any progress, whether it is "enough" or not, by either standard.

Euclidas the industry did not divulge how much more safety they were going to provide with the new tank cars. Unfortunately, reality caught up with this tactic by the practical demonstration of several recent train wrecks.
Whenever there is an attempt to obfuscate, stall, minimize and generally belittle the concerns of the "general public" once reality catches up credibility is lost. The public is not interested in excuses for why it should permit ~10 oil train wrecks annually, since eventually one of those will be in a populated area. Silly posturings about no such thing as "perfect safety" will only fuel the fire and what will happen then will not be to the rails' likings, with potentially ruinous liabilities and mandated shut downs as a hazard to public health. The time for the rails to act is now, no longer being dazzled by short-term riches. Embargo Bakken crude oil shipments until such time that the safety issues can be addressed, if possible.
C&NW, CA&E, MILW, CGW and IC fan
"Embargo Bakken crude oil shipments until such time that the safety issues can be addressed, if possible."
Can they legally do that? I was under the impression they, as a common carrier, must accept all cargo.
One of my favorite Simpsons quotes of all time came from Mayor Quimby in reference to the mob that was protesting the tax he had to enact to fund the Bear Patrol the citizenry wanted:
"Are these morons getting dumber or just louder?"
Ok, a bit extreme, but the basic point is there. On a local forum, someone was shocked about how crude train wrecks have gone up 37% since 2008, not understanding that the railroads are hauling something like 8000x more crude than in 2008. Lots of nasty stuff gets transported every day, but the crude oil trains are big and scary and a wreck or two that is widely shown gets them all worked up. Never mind the fact that certain factions are pushing hard for the KXL pipeline and these wrecks are great at promoting that - even in parts of the country that pipeline would not affect at all.
With so many people growing up in cul-de-sac neighborhoods and working white collared/service type jobs (and electing leaders of the same ilk), there is a major societal disconnect from real industry in the country anymore.
People want their cheap gas, but they don't want the oil transported. (Or at least in a manner visible to them)
Mayor Quimby wasn't that far off.
It's been fun. But it isn't much fun anymore. Signing off for now.
The opinions expressed here represent my own and not those of my employer, any other railroad, company, or person.t fun any
EuclidNobody is advocating “perfect safety.” Of course that is impossible. What Secretary Foxx is advocating is “as safe as possible.”
Alas, many people equate the two. Reality says otherwise.
People who don't understand where the fuel for their Rolls Kanardly comes from are the same people who don't know where their food comes from.
