Interesting articles in Spring 2008 Aspire Concrete Bridge magazine, showing the type of damage that can occur from a rail tanker fire.

You might need to right-click and download the PDFs for the "Protect" and "Evaluate" articles.

Here's an article about a sustained fire under the Interstate-85 bridge in Atlanta in March 2017.

Note:
• I am not a civil engineer, and have no access to damage assessments
• the rail tanker fire on the #CrimeaBridge was on, not under the bridge

usatoday.com/story/news/201…
Sample engineering assessment of damage to road bridge after rail tanker fire underneath it.
• important to know what burned and for how long
• Figure 3 shows the mapping of certain damage indicators to the piers near, and span above, the rail tanker.

aspirebridge.com/resources/Stod… ImageImageImageImage
If this photo is accurate:
• rail bed beside burnt car appears to have sunk 10-15 cm
• some concrete sleepers appear to be missing there
• steel channel without sleepers between the rails is missing
• side of bridge behind men appears to have sagged

Image
Don't know when this video was taken, but while these cranes are on the bridge trying to remove the rail cars (hours? days?) it is doubtful trains can travel on the other tracks.

Especially if the cranes need the tracks during any part of the operation.

This part of the bridge appears to be where the sunken rail bed is in other photos.

I am not a civil engineer or railway specialist, but I would expect a detailed damage assessment like this (or better) before using that bridge.

aspirebridge.com/resources/Stod…

Image
Closer video of damage to the structure of the bridge.

Both upper and lower steel maintenance walkways have melted and sagged. This steel failure is an indicator of the heat energy coming from the tanker fires.
Even after the blast, how bad is Russia's security on Crimean Bridge? Even on the rail bridge, someone is openly taking video, then uploading:
• repair progress
• rail and rail bed damage
• which suggest how much heat released
• road bridge damage

Repair progress. At the time of video, of the 7 tank cars that caught fire:
• 2 complete cars remain on rails
• 1 car has tank removed, but frame and bogies remain, still coupled to next car's bogie
• 2 cars have 4 bogies left
• 2 cars fully removed

en.wikipedia.org/wiki/Bogie
The heat is so intense that:
• the rail under the wheels collapsed
• the rail car axles warped

Priceless information for fire investigators, civil engineers, metallurgical engineers, bomb damage experts. ImageImage
Two days ago, @zahed gave an initial assessment from the photos & videos available then. His civil engineering degree gives him a better foundation to understand them than my industrial systems engineering degree. I'm following now for any updates.

Image
@zahed Rail bed damage.
• apparent sinking under 2 remaining tanker cars
• crushed stone between concrete sleepers missing
• suggests damage to underlying box structure

Maybe bridge is too weak to bring back cranes to lift tanks off, and rail too damaged to pull those cars away. ImageImage
@zahed It seems:
• on one end of the fire, bogies & wheels have fused from the heat and cannot be pulled
• on the other end, the rail bed and underlying structure are too weak to bring back the cranes

This might be why all the people in orange vests are there: looking for solutions. ImageImageImageImage
@zahed This video also show poor state of road bridge:
• intentionally bottlenecked to one lane
• red/white barriers adjacent to remaining rail cars
• no traffic on it - people on foot looking at it
• deflection and slant obvious, matches earlier video released by Russia ImageImageImageImage
@zahed Around 20-second mark of earlier video from a car driving off that damaged section of road bridge, you hear a kerthunk.

This might be normal for such joints, or it may be from a larger deflection due to the explosion destroying the adjacent road span.

Image
This @ConversationUK article released a few hours before the video from atop the rail bridge has 2 engineering professors - experts in bridge safety and blast engineering - assessing the damage revealed at the time. I'm interested in their updates too.

If you come to Palomino early enough on a weekday, the soup of the day may still be available.

Having lunch here now at 1.30pm and first time for me, and it is heaven.

Clam chowder with a delicacy in the spices and herbs you wouldn’t expect from a “BBQ Joint”.

Thank you Chef. My photo of my clam chowder with unexpected cornbread loaf on the side.
My mistake. CORN chowder, not clam chowder as I said above.

First bite blew me away, so I tweeted right away. They have a similar classic base, IIRC.

I can’t eat pork, so I got it without bacon garnish (therefore also vegetarian).

For those who do 🐖, party on people. My photo of chalkboard sidewalk sign.
For “main course” you need video, not photo.

This is Elote Taco Salad, with the smoked turkey I added, to the music of Talking Heads “Burning Down the House” which Palomino provides with your meal.

After the soup, at least half of this will go home for dinner/midnight snack.

I was going to tweet about my early dinner tonight at Palomino (cliché food pics) but just got hit with wall of SWEET sound when I went downstairs to use the washroom, and opened the steel door to basement concert hall.

WOW.

This is "Olde Ghosts" warming up - in this program. My photo with permission of Olde Ghosts 4-piece band warming up (I'd say they're already on fire) as I went to basement washroom at Palomino (shared with underground concert hall).
In the program they are listed as "Old Ghost" which may just be a miscommunication between Palomino mgmt and Band mgmt. Still gets the message across.
I am a nerdy 58-yr-old engineer who surprises people with 2 unexpected traits: a love for good metal, and endless jokes.

On the latter, I am like Leslie Nielsen who could easily get even people braced for his hidden fart accordion to crack up. But I'm not using one....yet.👺
With metal, I was raised with Indian music my parents played, like the Pakeezah soundtrack, until the cassette literally broke.

This is one of the songs from that movie. It builds until Meena Kumari (Indian's Marilyn) dances with those 2 😍 backups.

Kinda proud of myself. Also.. life is hilarious.

I’ve been eating a lot of rich, flavourful food recently, and I went from a salmon/capers omelet at OEB to the passcode protected washroom in food court at Fifth Avenue Place. Took a massive, relaxed dump.

Laughing as I type.
So I’m washing my hands - even had the foresight to take a restaurant napkin to dry my hands and use on the door lever to exit (trust me on this) and a distinguished gentlemen t about 60 walks in.

And visibly buckles, and groans.

I’m trying not to laugh out loud.
I step out of washroom and all of this is hitting me as I walk slowly to exit escalator, down to a bench on 5 Ave, where I am typing this now.

I’m almost crying not to burst out laughing.

And the Punjabi woman security guard sweetly asks me “Are you OK?”

No, Bhenji. I’m not.

@tylerblack32 @TheBreakdownAB @KmarkovCTV @picardonhealth @JenLeeCBC @MurrayManera @JSJamato @gabefabreau @drDavidKeegan @amandalhu @CalgarysChild @MarciaOnTheGo pbs.org/newshour/show/…Ali Rogin: Dr. Nagata, thank you so much for joining us. Social media children, lots of questions, few answers. What did your study find? Jason Nagata: We followed 12,000 preteens over three years and we actually found big rises in social media use. So during that period, social media on average increased from seven minutes a day to over 70 minutes a day. So a tenfold increase. And in our analysis, we actually found that rises in social media from year to year among these 9 then 10 then 11-year olds were actually associated with future depressive symptoms in the following year. So I thin...
Ali Rogin: So what you're saying is that you found the correlation here to be with social media use leading to more depressive symptoms, not the other way around. You're saying that depression doesn't necessarily indicate use of social media? Jason Nagata: Yes. In our study, were able to follow these same 12,000 kids year to year. So were able to look at both their depression and their social media use every single year. And so we could look at patterns in their use. And we found that those kids who had big spikes in their social media use from year to year then subsequently had bigger sp...
Ali Rogin: And talk to us about the size and the scope of this study. This sounds massive. How did you track this many children and has that been done before? Jason Nagata: So, yeah, the data comes from the Adolescent Brain Cognitive Development Study. It is a national study that follows these 12,000 kids from over 21 different states, study sites across the U.S. and it's funded by the National Institutes of Health and is I think one of the largest studies on child development and social media and brain health ever.
Ali Rogin: That's such a fascinating ancillary piece of information that you found in looking at this data. I do want to ask though, what is your advice for parents with the understanding that this data brings us to. Jason Nagata: Yeah, we actually looked at parent actions for rules and monitoring in the study and we actually found that the biggest predictors of kids screen use was actually their parents screen use. And as a new parent I think it's really important to practice what you preach. So if you're going to tell your kids to put down their phones to important that you role model g...

🧵 Alberta's Reigning Queen of deceptive cherry-picked public health stats, Health Min LaGrange, was back at it Monday, this time over measles immunization.

Bonus Topic: Where is the source for the widespread claim that airborne measles is only infectious up to two (2) hours? Screenshot from Goa 5 May 2025 press release, where Health Min LaGrange made the same claim in the YouTube press conference: [below is the quote verbatim, but I would put sarcastic quotes around "facts"] "Quick facts • Currently, appointments in the central zone are available within one day, while in the south zone appointments are available usually within one to two days. • Following increased efforts to educate Albertans on measles and the importance of immunization, there has been a significant rise in immunizations across the province. Since March 16, there has been a 67...
Excerpt from GoA lengthy web page on measles "How measles spreads Measles is an extremely contagious disease, spread easily through the air. You do not need to be in direct contact with someone who is infected. You can get measles just by passing through a room or location where a person who is infected was up to 2 hours before. The person who is infected does not still need to be there to put you at risk of disease. Measles can also be spread through coughing, sneezing, yelling, singing and breathing."

@TheBreakdownAB @JMeddings @PfParks @LukaszukAB @JenLeeCBC @GosiaGasperoPhD @Mark_Ungrin @dupuisj @DrFiliatrault @TimmCTV On the deceptive, cherry-picked measles immunization stats, LaGrange said "Since March 16, there has been a 67% increase in comparison to last year."

Let's look at actual graphs & data tables.

I was just treated TERRIBLY by @HyattCalgary. Manager just denied me service in restaurant for some vague reasons behind:

“None of the staff are comfortable with you and want to serve you.”

Huh? You just lost polite, loyal 20% tip customer. Maybe my friends too.

See you never.
The VP who oversees the restaurant was not on, but I left my business card.

My @Hyatt loyalty card, which shows zero as it has not updated for my purchases since February, when my car died, and I found walking there convenient. High prices, but matching food & service (!) Image
@Hyatt Now, I don’t care about my points, as I will never visit @HyattCalgary again, for any reason.

I won’t spend much time with the VP if he or she calls me. This is their problem to solve, not mine. I’ll get nothing from it either way - I’m gone.
