After Ohio rail disaster, Buttigieg is silent on restoring the safety standards Trump repealed

When a freight train carrying toxic chemicals derailed near East Palestine, Ohio, bursting into flame and sending up clouds of poisonous vinyl chloride smoke and gas, our immediate concerns were for the people in harm’s way and the train crew:

https://www.nytimes.com/2023/02/04/us/train-derailment-fire-palestine-ohio.html

If you’d like an essay-formatted version of this post to read or share, here’s a link to it on pluralistic.net, my surveillance-free, ad-free, tracker-free blog:

https://pluralistic.net/2023/02/11/dinah-wont-you-blow/#ecp

But those immediate concerns were soon joined by a broader set of worries: that the entire rail industry presented a systematic danger, and the Ohio derailment was a symptom of a much deeper pathology that endangered anyone who lives near one of the rail corridors that crisscross America.

The rail industry is the poster child for corporate power, and rail barons were among the first targets of Gilded Age trustbusters who saw the rail monopolies as a threat to the prosperity and wellbeing of Americans, as well as the integrity of the American political system itself.

40 years of neoliberal “consumer welfare” antitrust — starting with Reagan and continuing through every administration since — has seen the American rail sector achieve levels of concentration that meet and exceed the corrupt, untenable degree of the late 19th century.

Like the original rail barons, the current crop (including the self-styled cuddly billionaire Warren Buffett), have gutted rail investment, skirted on safety, maimed and abused their workforce, smashed their unions, and placed the entire US supply chain in a state of brittle precarity:

https://pluralistic.net/2022/02/04/up-your-nose/#rail-barons

Like all monopolists, the rail industry has been able to capture its regulators, trampling evidence-based policy and replacing it with rules that benefit shareholders at the expense of the public, labor, and customers.

https://doctorow.medium.com/regulatory-capture-59b2013e2526

This regulatory capture is an inevitable consequence of market concentration. When an industry is composed of dozens of small- and medium-sized firms, they are unable to converge on a single story about which rules regulators should favor them with: some of those companies will want things the others don’t, and each will vie to produce evidence disconfirming the others’ claims.

But when an industry dwindles to a handful of cozy giants whose C-suites are stuffed with company-hopping executives who’ve done time at every major company in the sector, they converge on a single fairy tale about the best way to regulate their industry, and convert their regulators’ truth-seeking exercises into rigged auctions that they handily win:

https://locusmag.com/2022/03/cory-doctorow-vertically-challenged/

That’s what happened during the Trump years, when rail lobbyists secured the repeal of a long-overdue, hard-won safety regulation that would have required rail companies to replace the Civil-War-era brakes on their rolling stock with modern electronically controlled pneumatic brakes (ECPs):

https://jacobin.com/2023/02/rail-companies-safety-rules-ohio-derailment-brake-sytems-regulations

The repeal cost millions in lobbying dollars, but it was worth it. Shortly after the ECP rule was scrapped, Norfolk Southern handed millions in bonuses to its execs and did billions in stock buybacks, while laying offf thousands of workers:

https://www.fool.com/investing/2018/10/25/norfolk-southern-implements-massive-buyback-progra.aspx

Elections, we’re told, have consequences. After Biden won the 2020 presidential election, he made a string of excellent appointments — people like FTC chair Lina Khan, who hit the ground running with detailed plans for making sweeping, consequential changes that would blunt corporate power, reverse-Trump era abuses, and correct the dysfunctions that created a political base for Trump:

https://www.eff.org/deeplinks/2021/08/party-its-1979-og-antitrust-back-baby

But other Biden appointees arrive in office with much less ambition. Transportation Secretary Pete Buttigieg has spent his tenure as King Log, failing to take action on spiraling airline cancellations, confining his major enforcement action to fining foreign airlines while ignoring the out-of-control abuses of America’s domestic carriers, except for the also-ran airline Frontier, which accounts for less than 2% of domestic travel:

https://pluralistic.net/2023/01/16/for-petes-sake/#unfair-and-deceptive

There are striking similarities between the structural defects in the airlines and the rail companies: both are highly concentrated sectors who have laid off senior staff, attacked unions, and blown billions in public money on stock buybacks and executive bonuses, even as their service degraded.

Both industries have been sharply criticized by experts and industry veterans, who’ve called for specific regulation. In the case of the airlines, SWA pilots and flight attendants had sounded the alarm about antiquated scheduling systems; for the rail companies, it’s experts like Grady Cothen, formerly a top safety expert at the Federal Railroad Administration (FRA), who told Congress that without action on braking systems, “[there] will be more derailments, more releases of hazardous materials, more communities impacted”:

https://www.congress.gov/event/117th-congress/house-event/LC69424/text?s=1&r=9

Despite these warnings, and despite the near-misses and smaller disasters that led up to the 100-foot-tall fireball over Ohio, Buttigieg’s DOT has not moved to reinstate the Obama-era brake safety rule, deferring to the monopoly rail owners self-serving claim that there is no need for such a move:

https://jacobin.com/2023/02/department-of-transportation-train-brake-regulation-ohio-derailment/

Indeed, the FRA is currently considering a rule that would further weaken braking rules, reducing obligations to inspect, test and certify braking systems:

https://www.regulations.gov/document/FRA-2019-0072-0005

The rail labor unions — the best source of independent expertise on the daily operation of the freight system — say that this would be a disaster: “Following through with a final rule would only deliver yet another financial windfall to rail carriers by eliminating inspections, testing and repairs, and deferring routine maintenance”:

https://www.goiam.org/news/territories/tcu-union/carmen-division-tcu/rail-labor-files-joint-comments-on-fras-nprm-2/

Serving as Transportation Secretary to the President of the United States of America makes you one of the most powerful people in the history of the human race. The Secretary’s powers, while not unlimited, are extensive. The American people need a DoT that works for them, not one that weakens safety rules:

Industrial Brakes Market Share, Size, Future Demand, and Emerging Trends

A frictional tool known as an industrial brake is used to stop an inertia-spinning load or to keep a part in a stable position. The inertia load is typically brought on by several rotating components that must be stopped.

They convert the kinetic energy from friction between two surfaces into heat, which slows everything down. Employing industrial brakes in various industrial machinery sets them apart from automotive breaks.

Industrial brakes operate in all weather conditions, need less maintenance since they have fewer moving parts, and are simple to adapt for different purposes. These factors will probably increase the need for industrial brakes globally in the upcoming years.

Browse detailed - Industrial Brakes Market Revenue Estimation and Growth Forecast Report

Types of Industrial Brakes

The industrial brakes sector is divided into types based on their application, including mechanically, electrically, hydraulically, pneumatically, and other methods.

• Mechanically Applied Brakes

These brakes operate, when two surfaces to rub against one another and creating frictional forces. The frictional surfaces' surface area and the applied actuation force significantly impact a brake's stopping power or capacity. The working surfaces experience high friction and wear.

• Hydraulically Applied Brakes

A hydraulic brake is a configuration of braking mechanisms that transfers pressure from the regulating mechanism to the braking mechanism using brake fluid, generally containing glycol ethers or diethylene glycol. Additionally, the majority of brakes in the industrial brakes market are hydraulically operated.

• Pneumatically Applied Brakes

Practically every field of mechanical engineering uses disc brakes that are directly pneumatically applied. Here, compressed air generates the actuating force, while spring force releases the brake.

• Electrically Applied Brakes

Electronic brakes employ an electrical current or magnetic actuation force to slow down or stop the rotation of a spinning component. They are utilized in applications requiring quick response times and accurate tension management in industrial and automotive braking systems.

What are air cylinders used for? In manufacturing industries, pneumatic cylinders will often be used for opening valves, doors,taking things on or off conveyor belts and lifting heavy objects. In the automotive industry, pneumatic cylinders have a different role. They're used in cars and trucks to be used for suspension and brakes. What is meant by an air cylinder? a cylinder in which air is compressed by a piston, in which compressed air is stored, or in which a piston is driven by air pressure. How many types of air cylinder is used? There are three main types of pneumatic cylinders, including: Single Acting Cylinders. Double Acting Cylinders. Telescoping Cylinders. What is the working principle of cylinder? Image result for air-cylinders The operation of hydraulic cylinder is based on Pascal's principle. According to Pascal's principle, the pressure is equal to the force divided by the area on which it acts. A pressure used on a piston produces an equal increase in pressure on the second piston in the system.

CKD tie rod cylinder with brake is a type of hydraulic cylinder, It comes with a tie rod design and a built-in brake. The tie rod design refers to the use of rods that connect the piston and cylinder head and provide stability and support, while the brake allows the cylinder to stop and hold a load in place. This type of hydraulic cylinder is commonly used in industrial and manufacturing applications where precise control and stopping power is required.

The industry group American Association of Railroads, of which Norfolk Southern is a member, has also fought stricter safety standards including an updated braking system. Electronically Controlled Pneumatic brakes, or ECP brakes, can decrease train stopping distances and could have prevented the derailment last week, according to The Lever. Norfolk spent years lobbying against the use of these brakes, and the Ohio train was not outfitted with the technology.

Ohio Train Derailment Reveals Danger of Plastics Boom and Corporate Cost-Cutting

[frodo-with-glasses]

More Reading Thoughts: A Shortcut to Mushrooms

"[Frodo] was lying in a bower made by a living tree with branches laced and drooping to the ground; his bed was of fern and grass, deep and soft and strangely fragrant. The sun was shining through the fluttering leaves, which were still green upon the tree." HELLO I WANT A BED LIKE THIS HOLY COW

LOL Pippin like "I would've eaten all the bread and not saved any for you if Sam didn't stop me" 🤣

"I don't want to answer a string of questions while I am eating. I want to think!" "Good heavens! At breakfast?" Have I mentioned that I love Frodo and Pippin—

Frodo sees his kid cousin running in the grass and singing and thinks to himself "🥺 oh I can't possibly take him and Sam into danger with me, look at them"

I love Frodo's entire conversation with Sam here. If I tried to list my favorite lines, I'd be copying the whole thing. Frodo doesn't want to put Sam in danger, because he loves him, but Sam is extremely loyal and willing to walk into hellfire for Frodo, because he loves him. It's just such a sweet exchange that tells you so much about these characters. I'm love them boys.

Also Frodo being surprised that Sam's become so philosophical haha

Frodo: "We'd best get going; we slept late." Pippin: "You mean you slept late." HAVE I MENTIONED—

Frodo: "I'm not going to take the road. I'll cut straight across country to the Ferry." Pippin: "What, can you fly??"

Pippin: "Short cuts make long delays! Besides, I was hoping to stop at the inn for some good beer." Frodo: "Well, that settles it! Short cuts make long delays, but inns make longer ones."

Also Sam stalwartly like "I'll go with you, Mr. Frodo," but also inwardly like ":-C but the beer tho"

And now we return to another hiking section, about which I have very little to say except that Tolkien's description of the natural environments of the Shire is extremely beautiful and I too would want to hike there

And now we interrupt your regularly scheduled pleasant hike for some bone-chilling horror

It's hard to imagine in the modern age—when tornado sirens and jet planes and faulty car brakes all probably make noises not unlike that of a Ringwraith's call—but to hobbits who have never heard a noise louder or more frightening than a thunderclap, a high, sustained, almost industrial screech like this must seem like the most terrifying and otherworldly thing.

(Also nobody tell Pippin about the white bellbird, which has a call like the emergency alert system at a volume comparable to a pneumatic drill)

Pippin: "Oh good, it's Farmer Maggot :-D" Frodo: "OH NO IT'S FARMER MAGGOT D-8"

It's such a shame that we know so little of Frodo's childhood, but the fact that he was a Certified Scoundrel(TM) who was prone to stealing mushrooms and got his butt whooped over it is absolutely hilarious 🤣 How ever did a naughty kid like him become the erudite sweetheart we know and love??

Pippin like "chill bro, he's a mutual friend of mine and Merry's, we're good!" Meanwhile Frodo is sweating buckets LOL

It's so cool that Pippin gets to be the leader in this section. And what a fearless leader he is! Of course he's not in any danger at all, but it just says so much about him that he waltzes down the lane to Farmer Maggot's house without a care in the world while Frodo and Sam are both terrified 🤣

Also I adore Farmer Maggot's hospitality

Sam giving Farmer Maggot the side eye because he whooped Frodo over the mushrooms years ago X-D

"I recollect the time when young Frodo Baggins was one of the worst young rascals of Buckland." I MEAN JUST IMAGINE

Farmer Maggot's story about the Ringwraith is SO GOOD. I love how much courage this round old hobbit has in him.

Farmer Maggot: "Moral of the story, ya never should've gone to Hobbiton. Clearly ya got mixed up with weird people." Sam: >:-C

Also Farmer Maggot cheerfully being like "don't worry, if they come after ya again, I'll deal with 'em for ya!" is so sweet and so ballsy X-D

Also Farmer Maggot is SO FREAKING SMART, and so generous. I think it's Merry who says later that he's got a lot more going on in his head than his genial appearance might let on, and he's right. He can see that Frodo and co. are in trouble, and he immediately offers his help. What a solid dude.

And here we see Frodo's silver tongue at work once again!

"I've been in terror of you and your dogs for over thirty years... It's a pity: for I've missed a good friend."

This line actually made me stop and think, bruh. How many friendships do we miss out on because we let the mistakes of our younger selves dictate our future?? I can think of lots of dumb things I did as a kid, and I'd be so embarrassed to run into the people that I wronged in my stupidity...but who knows? Maybe they're good people. Maybe they'd even be my best friends, if I got over myself. Food for thought.

And speaking of food, I want to have dinner with Farmer Maggot and his family and farm hands X-D

Ohhhh the suspense of the hoof-falls in the foggy lane is SOOO GOOD

WHO'S THAT POKEMON??

IT'S MERRY BRANDYBUCK!!

And his humor is in absolute top form LOLOL

"When it grew foggy I came across and rode up towards Stock to see if you had fallen in any ditches. ... Where did you find them, Mr. Maggot? In your duck-pond?"

HAVE I MENTIONED THAT MERRY IS MY FAVORITE HOBBIT

Also, the fact that Mrs. Maggot packed a basket of mushrooms for Frodo makes me very happy X-D

In 1957, Cadillac didn’t merely lead the Motor City’s luxury class. It dominated and defined the category. 

As we page through Cadillac’s catalogs and advertising materials for 1957, we can’t help but notice the spirit of downright arrogance. Amid the images of millionaires in Homburgs and Stetsons and ladies in fur coats enjoying their Cadillacs, the headlines swagger: “Magnificent beyond all expectations,” and “A single glance tells the story.” One of the more modest lines, in fact, is “You will make motordom’s soundest investment.”

Boasting is never good form, or so they say, but here you can see how Cadillac felt entitled to crow a little. With calendar year sales of more than 150,000 cars in 1957, the General Motors premium brand didn’t just lead the Motor City’s luxury class. It towered over the category with 50 percent more volume than Packard, Lincoln, and Imperial combined. In sales at least, Cadillac owned the U.S. luxury car market in those days, leaving the other three brands to clean up the scraps.

Underneath, Cadillac in ’57 was the first GM division to employ the cruciform or X-style chassis frame, developed in partnership with the industry’s leading frame manufacturer, A.O. Smith, which allowed GM body engineers to drop the footwells and roofline several inches. The Eldorado Brougham (above) also used GM’s new pneumatic suspension on all four wheels, while the rest of the line got by with leaf springs at the rear that year.  Neither the air springs nor the X-frame ultimately proved out, however, and Cadillac adopted a conventional perimeter frame in 1965.

The brand’s all-new sheet metal for ’57 was crafted by veteran Cadillac studio chief Ed Glowacke and crew, blending elements from previous Motorama show cars. Cadillac’s semi-custom Eldorado models, the Brougham, Seville, and Biarritz, were treated to their own unique sheet metal as well. The Eldorado Brougham was the first GM production car to wear the industry’s new 5 3/4-inch quad headlamp system.

The base model Sixty-Two four-door hardtop was Cadillac’s biggest seller in MY 1957 with more than 32,000 vehicles delivered. At $4,713, it cost more than twice as much as a new Chevrolet Bel Air, and when we say “base model” we note that Hydra-Matic, power steering, and power brakes were all standard. The most expensive Cadillac for  ’57 was the limited-production Eldorado Brougham, which at $13,704 cost more than the average new home that year ($12,200). The well-dressed Fleetwood Sixty Special (above and below) was another big seller at 24,000 units—despite the steep list price of $5,539. But then it was motordom’s soundest investment.

I remember early on in the trump administration- I was sitting at the mechanic's lobby and he was on the news with a giant stack of papers wrapped in a big red ribbon. And he talked about how the regulations imposed by previous administrations got in the way of business and prevented every day americans from reaching the american dream. And he took a pair of shears and cut the ribbon, symbolically cutting the red tape, as a promise to undo all regulations that hot in the way of moving forward.

And I looked to the woman waiting in the lobby with me, in her 60s, who shook her head along with me at the gesture, because we both lived on a low income side of town and people in our tax bracket know what happens when regulations are slack- people get sick, they get hurt, they die.

Disaster happens when people are careless and each regulation is written in blood.

Fuck that guy.

Picture id/transcript: (a screenshot of a news report by Heather Cox Richardson from february 15 2023)

But the derailment of fifty Norfolk Southern train cars, eleven of which carried hazardous chemicals, near East Palestine, Ohio, near the northeastern border of the state on February 3 has powerfully illustrated the downsides of deregulation. The accident released highly toxic chemicals into the air, water, and ground, causing a massive fire and forcing about 5,000 nearby residents in Ohio and Pennsylvania to evacuate. On February 6, when it appeared some of the rail cars would explode, officials allowed the company to release and burn the toxic vinyl chloride stored in it. The controlled burn sent highly toxic phosgene, used as a weapon in World War I, into the air.

Republican Ohio governor Mike DeWine has refused federal assistance from President Biden, who, he said, called to offer “anything you need.” DeWine said he had not called back to take him up on the offer. “We will not hesitate to do that if we’re seeing a problem or anything, but I’m not seeing it,” he said.

Just over the border, Pennsylvania governor Josh Shapiro, a Democrat, said that Norfolk Southern had botched its response to the accident. “Norfolk Southern has repeatedly assured us of the safety of their rail cars—in fact, leading Norfolk Southern personnel described them to me as ‘the Cadillac of rail cars’—yet despite these assertions, these were the same cars that Norfolk Southern personnel rushed to vent and burn without gathering input from state and local leaders. Norfolk Southern’s well known opposition to modern regulations [requires] further scrutiny and investigation to limit the devastating effects of future accidents on people’s lives, property, businesses, and the environment.”

Shapiro was likely referring to the fact that in 2017, after donors from the railroad industry poured more than $6 million into Republican political campaigns, the Trump administration got rid of a rule imposed by the Obama administration that required better braking systems on rail cars that carried hazardous flammable materials.

According to David Sirota, Julia Rock, Rebecca Burns, and Matthew Cunningham-Cook, writing in the investigative journal The Lever, Norfolk Southern supported the repeal, telling regulators new electronically controlled pneumatic brakes on high-hazard flammable trains (HHFT) would “impose tremendous costs without providing offsetting safety benefits.” Railroads also lobbied to limit the definition of HFFT to cover primarily trains that carry oil, not industrial chemicals. The train that derailed in Ohio was not classified as an HHFT.

Nonetheless, Ohio’s new far-right Republican senator J. D. Vance went on the Fox News Channel show of personality Tucker Carlson to blame the Biden administration for the accident. He said there was no excuse for failing infrastructure after the passage last year of the Bipartisan Infrastructure Bill, and said that the administration is too focused on “environmental racism and other ridiculous things.” We are, he said, “ruled by unserious people.”

[princess-of-the-corner]

So I did a bit of studying on subway train brake systems and turns out the emegency brakes are pneumatic, not electric.

Easy way around the guy not just throwing the switch then and there? Someones been skipping a bit on the maintenance checks and now it's a little seized up, and the heros can't risk trying it cause enhanced strength means enhanced chance to just rip the handle off.

So now the train driver is trying to break the handle loose to engage the brakes while the heros are trying to manually stop the train. Cinnabars doing the old fashioned 'put your back into' style while Queen Bee is doing a more Spider-Man approach of making a net with the string of her top to catch the train.

Tbh yeah as much as I want the Chloé 🤝 Kevin = hijacking a train solidarity, I think it's best if she doesnt' do that lmao

[objectum-kinkfessional]

sitting in traffic is fine actually cuz it means i get to stare at car ass

and i get to hear the 18wheeler next to me release its big pneumatic brakes and start growling

[tearsinthemist]

A high-hazard flammable unit train was defined as a train going faster than 30 miles per hour with at least 70 loaded tank cars containing certain highly flammable liquids, such as crude oil and ethanol.

Electronically controlled pneumatic brakes work on all train cars simultaneously. This allows the train to brake faster than when equipped with conventional air brakes, which are applied sequentially along the length of the train.

After this rule was enacted, lobbyists for railway and oil companies pushed to repeal it, questioning the effectiveness of electronic brakes and arguing that the cost of installing them was too high.

Then in 2018, under the Trump administration, the Department of Transportation repealed the rule based on government reports that determined equipping high-hazard cargo trains with electronic brakes was not economically justified.

[meret118]

About four years later, while railway interests donating “more than $6 million to GOP campaigns,” there was an enormous public safety disaster in the White House named Donald Trump. Trump’s administration rolled back all kinds of safety regulations for transportation and for fossil fuel interests. Trump’s Department of Transportation rolled those minimum safety requirements back. Specifically, even those trains would not be required to be outfitted with the newer, safer, electronically controlled pneumatic (ECP) brakes. ECP brakes promise faster stopping and less destructive derailments, in part because they offer a more robust deescalation of speed for each individual train car.

Air cylinders used for? In manufacturing industries, pneumatic cylinders will often be used for opening valves, doors,taking things on or off conveyor belts and lifting heavy objects. In the automotive industry, pneumatic cylinders have a different role. They're used in cars and trucks to be used for suspension and brakes. meant by an air cylinder? noun. : a cylinder in which air is compressed by a piston, in which compressed air is stored, or in which a piston is driven by air pressure. much air is in a cylinder? Normal-pressure cylinders are in the range 2000 and 2500 psig (140 and 175 bar) and low-pressure cylinders are in the range 480 psig (34 bar). an air cylinder work? Air Cylinders Information. Air cylinders are pneumatic linear actuators driven by pressure differential in the cylinder chambers. Compressed gas (typically air) acts as the power to impart a force and cause actuation. The compressed gas is allowed to expand due to the pressure gradient, and forces a piston to move in the desired direction. single action air cylinder? The cylinder can be single or double action. In a single acting air cylinder, the cylinder contains pneumatic porting for drive in only one direction. Single-action air cylinders frequently incorporate a return spring to the unpowered position.
