Thank you for uploading this series. Each episode is fascinating
What I don't understand about the blinding building, they didn't notice this during construction?
The train threw an axle due to an unattended wheel bearing that got hot and seized, sometimes called a hotbox, referring to journal boxes stuffed with oil-soaked rags that served to lubricate wheel bearings on trains up through mid-century. They had to be checked manually by hitting with a hammer when the train was stopped - a hotbox produces a different sound. The same thing happened in Palestine, OH, and it doesn't appear there's been any legislation since then about spacing and checking of heat detectors trackside. The same caused the big Frankford Junction Curve derailment in Philadelphia of a passenger train in the the 1940s, where cars endo-ed and were pierced with catenary supports when a hotbox seized.
Buying Chinese bearings???
Use only american we have Tonkin bearings here. Quility not cheep.
'fraid our freight carriers come under the tofu dregs category
Watched it on fire go by my house. Cheep bearing. We have quility bearings in
America.stop cheeping out at americans exspence.no more crap parts.
The weird TV format is what drove me away from tv. 10-15 min of content stretched over 45min. Lots of repetition and inane nonsense from 'I was there' wannabe reporters.
I love the reporter in the first calamity in Arizona. "It reminded me of the Apocalypse". Wait a minute, there's never been an apocalypse. How can it remind you of something that you've never experienced?
She's clearly a time traveler and survivor.
The thing I thought was funny is that it was like the craziest thing she's ever seen 😂 nothing ever happens here in Arizona
Please keep in mind architecture and engineering are different trades.
Yes, architects will actually visit the jobsite, whereas engineers do not. Very important piece of information to know.
1. That truss bridge looks like it hasn’t had a coat of galvanic paint in many years. Another point of future failure.
2. Architects may design what a building looks like but it takes engineers to determine how it’s built and should be aware of how light is focused by reflective concave surfaces. Any kid introduced to astronomy using a reflective telescope could tell you what happens to light on a concave surface.
3. The sinkhole highlights a big problem in the USA. Companies, counties and states skip maintenance costs and cut construction costs. How many stories in this series are about incidents where maintenance was not carried out with the regularity necessary or short cuts or cheaper material selection during construction to save a buck?
I live right by the bridge, I've been there many times throughout the years (it's a nice place to hang out, walk/jog, longboard, bike) and that bridge looks even worse in person. It's a really old bridge. The lightrail bridge is also right next to it, it's modern and has pretty lights at night, but the old train bridge right next to it kind of makes it look like an eyesore. It doesn't look historic, it just looks old.
I am going to make a radical suggestion for handling old railroad bridges. The radical crazy suggestion is----can we have trains SLOW DOWN when crossing them?
Most railroad bridges already have "go slow" speed restrictions.
Most trains go at less then 20 mph over most of their tracks.
In many ways 20 mph can be to fast given the length of Most trains today
The length and weight of trains today as compared to those of 100 years ago is significantly larger. Trains today are too heavy and too long for safety--train crews have been saying this for decades
The part of the Tempe bridge that was completely destroyed was a timber trestle, treated with creosote, a preservative. In hot conditions creosote is very flammable. When the train derailed, there would have been sparks from steel car frames or wheels skidding on the sides of rails.
The sinkhole in Ohio was produced by the leaking sewers, not by the weight of the traffic. If the dirt had not been washed out from under the road, there would never have been any problem, regardless of how heavy the traffic was. They may have paved over the old brick pavement, but that would not have affected the road. It was the void under the pavement.
LOL...the renaissance of LA??? (I guess the sidewalk pooping started after that)
That concert hall looks like an ugly hot mess, like a bunch of boxes someone knocked over. Modern architects have no sense of beauty or design, not like the Ancients did.
A massive hole has appeared in the road - police are looking in to it..... ;)
The building in LA is just the ugliest building I have seen and a waste
Turn it black Matt,so you'll know how heat works.
from Indonesia. I really enjoy watching these knowledgeable series. I am not engineer, but the real events & the explanations give me insights. Thanks a million.
BAD enough being in OHIO but to have the ground sink under you in Ohio and falling into sewage in Ohio? O HECK NO!!. - Y.T. Michigan😛😛😛😛 (oh chill. just having fun)
The town of Tempe is typically pronounced "Tem-PEE" not "Tem-pay". I know, we have a lot of strange words. Lol
That's not the only time an "artsy" looking building has caused problems, there's a building in London that also bakes things in the sun. I guess that's what you get for putting form over functionality.
100 +/- years ago. Architects/builders would factor in, where the....house or building... sat. How sun would help or hurt it. plant trees to shade or protect it. put windows here to catch light. high roof to let the heat out. rotate it 90 to change what rooms were getting wind and sun.... wind and so on. NOW? architects just want to be impressive and dont give a crap about function. just make it flashy. make me famous and run away. .....25 years ago digital simulations were not capable of calculation...... so use your brain. you put shiny shit in a sunny spot and you fry ants. any 10 year old boy knows this. Lockheed skunk works designed a mach 3 plane with slide rules in 1966 and you need a computer to tell you shiny concave surface will focus sunlight? REALLY?
After spending 2 weeks in Europe recently makes me dislike the cold modern buildings even more. Within 50 years many are being abandoned and demolished. Not that that has anything to do with the video content, just a thought.
‘The building was blinding freeway traffic’ well don’t come to Australia sweetheart as when I drive to work in the morning I drive in to the blinding sunlight and often can barely see the road. And then when I drive home in the opposite direction the same as do all drivers as the sun sets. And you’re complaining about a building? Does she drive the rest of the time with their eyes closed?
The story of the Varsa ship was very similar to the Marie Rose that sunk for the same reason, too many guns high up then a turn to port made it keel over letting water in the gun ports. It too was resurrected and now in a museum.
You know that lady who was under the bridge when it caught on fire brings it up every chance she gets to everybody she meets. I mean she mentioned that she was right in between the two trusses like six times In one minute.
i get the derailment, but didnt address why the heck the whole train caught fire so quick
If you look at a similar fire that happened in Poughkeepsie New York, the railroad ties on the bridge are coated in creosote which is highly flammable - so the fire just spreads horizontally and is very difficult to put out. The big difference here is this bridge is not very high off the water and they were able to spray water from the lake.
Knowing that there's always this potential, the bridge in Poughkeepsie had a water system on it for firefighters to be able to have water, but it was broken and not been repaired so there was no water available on the bridge itself. The bridge was abandoned and is now a bike path.
story repeats over and over, we forgot, we were cheap, we did not model it correctly, where does the dirt go ?
thank god i live in canada, it must mean that canada is a good place to live................
Bianca Buono is a lovely ambassador for Tempe
That structure in Los Angelos is ugliest as it can be ,what a waste of money
Art and architecture is subjective.
The woman on the bike is overdramatic
I hope Camille bought lottery tickets after that.
That pronunciation of “Tempe” hurt.
what an ugly building
I visited the Vasa around 1962 . It was when they were pouring the special solution of water over the ship. I didn't get the full story till I watched this documentary.
Seems like a lot of trouble (and expense, I expect) to raise a ship that accomplished nothing. I'm all for preserving history, but that ship is only about an hour's worth.
Great having engineering experts spout the obvious is priceless! 🤣🤣
"the entire valley could probably get a glimpse of what was happening here." Yes, you could. I was driving home from work on an overnight shift and saw it from North Scottsdale. As I drove south, the smoke clouds got larger and larger and thicker and thicker. It was easy to see as it was an absolutely clear morning otherwise.
The saving of the Swedish ship was phenomenal. I like that best.
I bet I can bring in an anomaly that engineers forgot about... Uhm those railways have railroad ties and in high heat there is more moisture absorption over any river/lake regardless if they are pressure treated and infused with oils, they will still expand given heat and moisture.
They're soaked in creosote. They burn like crazy.
White oak, most common tie material, has a tangential shrinkage of 10.5% and radial of 5.6%. Ties are cut 7 in thick by 9 in wide. So a good estimate of max thickness shrinkage is about 10% of 7 in or 0.7 in. That's just up and down. The suspension systems on cars could probably handle that.
Less corruption and more doing
She got millions for that
Corruption
I RAN CONDUIT ON TOP OF THE INTEL BUILDING IN CHANDLER ARIZONA BACK IN THE 80'S. WE RAN THE PIPE IN THE MORNING, IN THE AFTERNOON MY BOSS TOOK ME TO THE ROOF. THE RIGID CONDUIT LOOKED LIKE A ROLLER COASTER. WHEN WE CAME BACK UP IN THE MORNING, IT WAS PERFECTLY STRAIGHT. WE HAD TO GO BACK UP IN THE HEAT OF THE DAY, AND BACK OFF ALL FITTINGS TO LEAVE ROOM FOR EXPANSION. THEN TAPE ALL FITTINGS TO MAKE THE WATERPROOF AGAIN. WHAT A PAIN THAT PROJECT WAS. BUT THE ARIZONA HEAT DOES THINGS TO STEEL.
